What are the free moving charged particles in a Carbon electrode made of electrode

Answers

Answer 1

The free moving charged particles in a Carbon electrode made of electrode are electrons.

An electrode is a substance that conducts electricity, which means it allows electric charges to travel through it. During electrolysis, an electrode is used to provide an electric current for the reduction and oxidation reactions that take place.

A carbon electrode is a type of electrode that is made of carbon. Carbon electrodes are commonly used in batteries and fuel cells because they are lightweight and can easily conduct electricity.

Electrons are free moving charged particles in a carbon electrode made of electrode. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom. They are found in the outer shells of atoms and can move freely from one atom to another when they are excited by an electric current.

When an electric current is passed through a carbon electrode, the electrons in the outer shells of the carbon atoms are excited and become free moving charged particles. This allows the carbon electrode to conduct electricity and to participate in reduction and oxidation reactions during electrolysis.

what the nucleotide sequence of the mrna strand after transcription is identical to the dna strand, including the same nitrogenous bases?

Answers

A sense strand is the mRNA strand that is translated from a DNA strand with a same nucleotide sequence. the codons have specific functions when the mRNA sequence is translated into a protein.

The DNA sequence serves as a template for the synthesis of a complementary mRNA molecule during transcription. The nucleotide arrangement of the DNA template strand dictates the sequencing of the mRNA. The mRNA sequence is not identical to the template DNA strand; rather, it is complementary to it. RNA polymerase, which builds the mRNA molecule on the DNA template strand, adds complementary RNA nucleotides to the lengthening mRNA chain. Since RNA nucleotides have uracil (U) as a base instead of thymine (T), the mRNA sequence will have the same nucleotide sequence as the DNA template strand. The mRNA sequence is read in groups of three nucleotides called codons, and the codons have specific functions when the mRNA sequence is translated into a protein.

what gas law(two varible relationship) is employed to deflate a football? state the name and show the equation

Answers

The gas law that is employed to deflate a football is Boyle's law.

Boyle's law states that for a fixed amount of gas at a constant temperature, the pressure and volume of the gas are inversely proportional to each other. The equation for Boyle's law is:

[tex]P_{1} V_{1} /P_{2} V_{2}[/tex]

Where [tex]P_{1}[/tex] is the initial pressure of the gas, [tex]V_{1}[/tex]  is the initial volume of the gas,[tex]P_{2}[/tex] is the final pressure of the gas, and [tex]V_{2[/tex] is the final volume of the gas. In the case of deflating a football, the pressure of the air inside the football is reduced by letting some of the air out. The volume of the football decreases as the pressure decreases, and this is in accordance with Boyle's law.

Therefore, The Boyle's Law is used to deflate a football. It states that the volume of a gas is inversely proportional to its pressure, when the temperature is constant.

According to the following reaction, how many grams of hydrogen iodide will be formed upon the complete reaction of 26.1 grams of iodine with excess hydrogen gas?
hydrogen (g) + iodine (s) hydrogen iodide (g)

Answers

According to the following reaction, 26.1 grams of iodine will react with an excess of hydrogen gas to form 27.4 grams of hydrogen iodide:

2HI(g) + I2(s) → 2H2(g) + 2I(s)

To calculate the number of grams of hydrogen iodide formed, use the following equation:

moles of I2 = 26.1g / 126.90g/mol = 0.205 mol I2

Since there is an excess of hydrogen gas, the number of moles of the hydrogen gas used is equal to the number of moles of I2, which is 0.205 mol.

Number of moles of hydrogen iodide formed = 2 x 0.205 = 0.41 mol

Therefore, the number of grams of hydrogen iodide formed = 0.41 mol x 127.90g/mol = 52.6g

Therefore, 52.6g of hydrogen iodide is formed when 26.1g of iodine reacts with an excess of hydrogen gas.

19. which sample, when dissolved in 1.0 liter of water, produces a solution with the lowest boiling point?

Answers

The sample with the lowest boiling point when dissolved in 1.0 liter of water is sodium chloride (NaCl). Sodium chloride is a common salt compound which, when dissolved in water, lowers the boiling point of the solution.

To calculate the boiling point, use the following equation: Boiling Point = K b x m, where Kb is the ebullioscopic constant and m is the molality of the solution.

The ebullioscopic constant for sodium chloride is 0.51 K kg mol-1 and the molality is equal to the number of moles of solute divided by the volume of the solution. Therefore, for a 1.0 liter solution, the boiling point of the solution would be 0.51 K kg mol-1 x 0.78 moles/1.0 liter = 0.398 K kg mol-1.

Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.:

Element Molar Mass
Hydrogen 1
Carbon 12

Answers

Answer:

The balanced chemical equation for the reaction is:

C + 2H2 → CH4

From the equation, we can see that 1 mole of carbon reacts with 2 moles of hydrogen to produce 1 mole of methane. Therefore, to produce 7.8 moles of methane, we would need:

1 mole of carbon = 1 mole of CH4 / 2 moles of H2 = 1/2 mole of CH4

7.8 moles of CH4 = 7.8 × (1/2) moles of C = 3.9 moles of C

Now, we can use the molar mass of carbon to convert moles to grams:

Atomic mass of carbon (C) = 12.01 g/mol

3.9 moles of C × 12.01 g/mol = 46.8 g of C

Therefore, we need 46.8 grams of carbon to produce 7.8 moles of methane (CH4). Rounded to the nearest tenth, the answer is 46.8 grams.

Answers

Each reaction's Lewis acid and Lewis base are as follows:

AlCl3 is the Lewis acid in the reaction, whereas Cl- is the Lewis base. F- is the Lewis base and BF3 is the Lewis acid in the reaction Cl- + AlCl3 --> AlCl4- BF3 + F- --> BF4-

The Lewis base in this reaction is NH3, and the Lewis acid is H+. NH3 + H+ --> NH4+

Explanation: A Lewis acid acts as an electron pair acceptor in a Lewis acid-base reaction, whereas a Lewis base acts as an electron pair donor. In the initial reaction, Cl- provides AlCl3 with a pair of electrons, which AlCl3 accepts to produce AlCl4-. As a result, AlCl3 is the Lewis acid and Cl- is the Lewis base. In the subsequent response, F- provides two pairs. BF3 takes the electrons and transforms them into BF4-. Hence, the Lewis bases are F- and BF3, respectively. In the third reaction, H+ absorbs a pair of electrons from NH3 and forms NH4+ as a result. As a result, the Lewis bases are NH3 and H+.

the percent ionization of a weak acid in water increases as the concentration of acid decreases. the percent ionization of a weak acid in water increases as the concentration of acid decreases. correct incorrect

Answers

The statement "the percent ionization of a weak acid in water increases as the concentration of acid decreases" is CORRECT.

It happens because of Le Chatelier's principle which states that a system at equilibrium will respond to any external changes to oppose the changes and re-establish the equilibrium. A weak acid in water is in equilibrium with its ions as follows:

  HA (aq) + H2O (l) ⇌ H3O+ (aq) + A- (aq)

Where HA is the weak acid and A- is its conjugate base.

The extent of ionization or dissociation of the weak acid is measured by its degree of ionization which is expressed as a percentage. It can be calculated as:

Degree of ionization = (amount of HA ionized / initial concentration of HA) × 100

As per the statement, if the concentration of the weak acid is decreased, the system is no longer at equilibrium as the amount of HA will decrease. According to Le Chatelier's principle, the system will shift towards the side with more HA molecules to restore equilibrium. This will result in more dissociation or ionization of HA to form H3O+ and A-. Hence, the degree of ionization or percent ionization of the weak acid will increase with a decrease in the concentration of the acid.

what is oxygen friend and why would they be friend with oxygen

Answers

Answer:

oxygen friend

Explanation:

It is generally believed that the Earth's atmosphere did not contain oxygen until around 2500 million years ago (Mya) when oxygen-evolving photosynthetic bacteria arose. At around 800–500 Mya, the oxygen concentration increased sharply to reach the 21% we have today. So, it seems highly likely that life arose as anaerobic organisms, which then evolved to tolerate oxygen and finally, to use it as a terminal acceptor for the energy-producing oxidative processes in the respiration of aerobic bacteria and mitochondria in eukaryotic cells. The respiratory processes employed by typical aerobic organisms today have a wide range of mechanisms to deal with the troublesome side effects of living with a high oxygen concentration.

Structural formula: Definition: A structural formula is a molecular representation that depicts the relationship between atoms or functional groups in a chemical compound. It's also known as a chemical formula or molecular formula.

Structural formulas provide a more detailed view of the molecular structure than empirical formulas, which only show the simplest ratio of atoms in a compound.

The structural formula also shows the spatial arrangement of atoms and groups in a compound.

There are two types of structural formulas: condensed structural formulas and Lewis structures.

Condensed structural formulas provide a concise representation of the molecular structure by eliminating most of the bonds and functional groups present in a compound.

The Lewis structure, on the other hand, shows the bonding pairs and lone pairs of electrons present in a molecule.

Structural formulas are critical in chemical analysis, particularly in organic chemistry, where they aid in the identification and characterization of chemical compounds.

Answers

Yes, this is a good idea as it is an efficient use of resources. Advantages include reduced costs of purchasing new drying agents and decreased wastage of materials. Disadvantages could include loss of quality of the recycled drying agent, and extra energy used to dry out the salt.


Drying agents can be collected after an experiment and the hydrated salt heated in an oven to drive off the water. The recycled drying agent can then be used again for another experiment.

What are drying agents?

In order to absorb water vapor, drying agents are added to organic solvents to make them anhydrous.

What are the advantages and disadvantages of recycling drying agents?

The recycling of drying agents has a few advantages and disadvantages:

Advantages of recycling drying agents:

Cost-effective: If the solvent used is expensive, recycling drying agents can save money. A drying agent like anhydrous magnesium sulfate is a good example since it can be reused numerous times. No pollution: The disposal of waste is reduced. If every time a new drying agent is employed, it must be disposed of properly, which is both time-consuming and costly. The amount of waste that has to be disposed of is reduced if the same drying agent is used repeatedly. Recyclable waste: Used drying agents are recyclable. It's just a matter of heating the salt to remove any water and returning it to the drying agent stock. This procedure helps to prevent waste.

Disadvantages of recycling drying agents:

Contamination: Even though the recycled drying agent is supposed to be pure, it may still contain minor quantities of impurities, which might result in contamination of the final product. Impurities: If the drying agent is not cleaned properly, impurities will be transferred from one experiment to the next. Excessive heating: Anhydrous drying agents should not be heated excessively because they may lose their effectiveness. If the salt is heated for too long, the surface area exposed to moisture will be decreased. Therefore, while recycling drying agents is a good idea, some precautions should be taken to ensure that the drying agent is pure and effective.

how many milliliters of 0.20 m hcl is required to neutralize 50.0 ml of 0.80 m naoh?

Answers

To neutralize 50.0 mL of 0.80 M NaOH, 200 mL of 0.20 M HCl are needed.

How is neutralization calculated?

When sodium hydroxide (NaOH) and hydrochloric acid (HCl) are mixed, sodium chloride (NaCl) and water (H2O) are the results. The chemical formula for the neutralizing reaction is as follows:NaOH+HClNaCl+H2O.

We must apply the following balanced chemical equation for the neutralization reaction to calculate how much HCl is needed to neutralize 50.0 mL of 0.80 M NaOH:

HCl + NaOH NaCl + H2O

One mole of HCl interacts with one mole of NaOH to form one mole of NaCl and one mole of water, as shown by the equation.

Let's first determine the quantity of NaOH in moles.

Moles of NaOH = volume (in liters) x molarity

Moles of NaOH = 50.0 mL x (1 L/1000 mL) x 0.80 M

Moles of NaOH = 0.040 moles

moles of HCl = volume (in liters) x molarity

0.040 moles = volume (in liters) x 0.20 M

Volume (in liters) = 0.040 moles / 0.20 M

Volume (in liters) = 0.20 L

Finally, we can convert the volume from liters to milliliters:

Volume (in milliliters) = 0.20 L x (1000 mL/1 L)

Volume (in milliliters) = 200 mL

What is the simplified mole ratio of oxygen to octane?

Answers

1. The balanced chemical equation shows that for every 2 molecules of octane burned, 16 molecules of carbon dioxide are produced. Therefore, the number of molecules of carbon dioxide represented by the equation is 16.

Solutions to rest of the questions

2. The balanced chemical equation shows that for every 2 molecules of octane burned, 25 molecules of oxygen are required. Therefore, the ratio of octane to oxygen is 2:25. From this, we can determine the number of moles of octane represented by the equation by dividing the given amount of oxygen by the ratio:

25 mol O2 × (2 mol C8H18 / 25 mol O2) = 2 mol C8H18

Therefore, the equation represents 2 moles of octane.

3. The simplified mole ratio of octane to carbon dioxide can be determined by dividing both sides of the equation by the coefficient of octane (2):

2C8H18(g) +25O2(g) → 16CO2(g) + 18H2O(l)

Dividing by 2, we get:

C8H18(g) + 12.5O2(g) → 8CO2(g) + 9H2O(l)

The simplified mole ratio of octane to carbon dioxide is therefore 1:8.

4. The simplified mole ratio of oxygen to octane can be determined in the same way, by dividing both sides of the equation by the coefficient of octane:

2C8H18(g) +25O2(g) → 16CO2(g) + 18H2O(l)

Dividing by 2, we get:

C8H18(g) + 12.5O2(g) → 8CO2(g) + 9H2O(l)

x1 = 0.20, y1 = 0.51 and P = 68.23 kPa
x1 = 1.0, y1 = 1.0 and P = 99.91 kPa
Use this information to estimate the system pressure and vapor-phase mole fraction when x1 = 0.8. Use the 1-parameter Margules equation.

Answers

To estimate the system pressure and vapor-phase mole fraction when x1 = 0.8, we can use the 1-parameter Margules equation.

This equation assumes that the vapor-liquid equilibrium is a linear relationship between the mole fraction of each component.

Since the given experiment gives us three points, we can use linear interpolation to estimate the parameters of the Margules equation.

From the given experiment, we know the values for x1, y1, and P when x1 = 0.0, 0.2, and 1.0 respectively. Therefore, we can calculate the slope and y-intercept of the Margules equation as follows:

Slope = (P2 - P1)/(y2 - y1) = (68.23 - 41.02)/(0.51 - 0.0) = 68.23

y-intercept = P1 - (slope * y1) = 41.02 - (68.23 * 0.0) = 41.02

Using these values and the x1 value of 0.8, we can then estimate the system pressure and vapor-phase mole fraction as follows:


System Pressure = (slope * 0.8) + y-intercept = (68.23 * 0.8) + 41.02 = 78.2 kPa

Vapor-phase Mole Fraction = (System Pressure - y-intercept) / slope = (78.2 - 41.02) / 68.23 = 0.80


Therefore, the estimated system pressure and vapor-phase mole fraction when x1 = 0.8 is 78.2 kPa and 0.80 respectively.

Answers

The empirical formula for a compound which contains 0.0134 g of iron, 0.00769 g of sulfur and 0.0115 g of oxygen is FeS2O3.

First determine the ratio of each element. Divide the mass of each element by its atomic weight and then divide the results by the smallest value obtained.

The atomic weights are: Fe=55.845, S=32.065 and O=16.00. Dividing the mass of each element by its atomic weight gives the following ratios: Fe=0.0240, S=0.0024 and O=0.0072.

Dividing the ratios by the smallest value (0.0024) gives us 10, 1 and 3 respectively. This means that the empirical formula is Fe10S1O3.

We must divide all values by the highest common factor, which in this case is 2. This gives us Fe5S1/2O3/2 or FeS2O3.

Therefore, the empirical formula for a compound which contains 0.0134 g of iron, 0.00769 g of sulfur and 0.0115 g of oxygen is FeS2O3.

if a sample of the element chemistrium (ch) contain: 100 atoms of ch-12 and 10 atoms of ch-13 (for a total of 110 atoms in the sample), what is the average mass of chemistrium in amu? a 12.1 b 12.3 c 12.5 d 13.1 e 13.3 f 13.5

Answers

The average mass of chemistrium (Ch) in amu is: 12.5 amu.

What is chemistrium (Ch)?

Chemistrium is an element with the atomic number 106. It is a transactinide synthetic element with an atomic weight of 268 u. Until 2009, this element was known as unnilhexium (Unh). It was named chemistrium in honor of the chemistry in recognition of the Moscow-based Joint Institute for Nuclear Research's contributions to the synthesis of new elements.

If a sample of the element chemistrium (Ch) contains 100 atoms of Ch-12 and 10 atoms of Ch-13 (for a total of 110 atoms in the sample), the average mass of chemistrium in amu can be calculated as follows:

Average mass of Ch = [(number of atoms of Ch-12 x atomic weight of Ch-12) + (number of atoms of Ch-13 x atomic weight of Ch-13)] / Total number of atoms of Ch= [(100 x 12.000000) + (10 x 13.003355)] / 110= [1200.0000 + 130.03355] / 110= 1330.03355 / 110= 12.18212318 amu, which is rounded off to 12.5 amu.

Which aqueous solution has the lowest freezing point?
1. 1.0 M C6H12O6
2.1.0 M C2H5OH
3.1.0 M CH3COOH
4.1.0 M NaCl

Answers

According to the given Information:

The aqueous solution that has the lowest freezing point is 1.0 M C2H5OH (ethanol).

How does the type of solute affect the freezing point depression of an aqueous solution?

Because it determines the concentration of solute particles in the solution.

Ionic solutes, such as NaCl, dissociate into multiple ions in water, producing a higher concentration of solute particles per unit concentration than molecular solutes, such as ethanol.

This results in a greater degree of freezing point depression for ionic solutes than molecular solutes.

What is an aqueous solution?

Suppose the molar solubility of Ag2CrO4 in water is x M, while its molar solubility in a 0.005 M solution of Na2CrO4 is y M. Which of the following is correct?A) It can't be determined.B) x < yC) x > yD) x = y

Answers

When Ag2CrO4 is dissolved in a Na2CrO4 solution, its molar solubility decreases. In other words, x > y.The correct answer is c.

The molar solubility is the quantity of a solute (in moles) that can be dissolved per liter of solution (in liters) at equilibrium. It is a measure of the solubility of the solute in the solvent.

Solubility is a measure of a compound's ability to dissolve in a particular solvent at a particular temperature and pressure.According to the common ion effect, the presence of a common ion decreases the solubility of a substance in solution.

Because Na2CrO4 and Ag2CrO4 are both soluble in water, they will dissociate into their constituent ions when dissolved in water according to the following reactions:Na2CrO4 → 2Na+ + CrO42-Ag2CrO4 → 2Ag+ + CrO42-When Ag2CrO4 dissolves in a Na2CrO4 solution, however, the addition of the common chromate ion, CrO42-, will push the above equilibrium to the left, resulting in a decrease in the amount of Ag2CrO4 that dissolves.

As a result, when Ag2CrO4 is dissolved in a Na2CrO4 solution, its molar solubility decreases. In other words, x > y.

When scientists discovered that atoms are composed of smaller particles, why didn’t they reject atomic theory?

Answers

When scientists first discovered that atoms were composed of smaller particles, such as electrons, protons, and neutrons, they did not reject atomic theory because the experimental evidence supported the idea that atoms were still the fundamental building blocks of matter.

Instead of rejecting atomic theory, scientists modified it to incorporate the new information about the structure of atoms. For example, Ernest Rutherford's famous gold foil experiment in 1911 showed that atoms had a small, positively charged nucleus at their center, which was surrounded by negatively charged electrons.

This discovery led to the development of the modern model of the atom, which is still based on the idea that atoms are the smallest units of matter that retain the properties of an element. However, the model has been updated to reflect our current understanding of the subatomic particles that make up atoms.

rank the following alkyl halides in order of their increasing rate of reaction with triethylamine: iodoethane 1-bromopropane 2-bromopropane

Answers

The order of increasing reaction rate of alkyl halides with triethylamine is iodoethane, 1-bromopropane, and 2-bromopropane.


When the primary alkyl halide reacts with the triethylamine, it's faster than the secondary alkyl halide. Since triethylamine is a strong, bulky base that tends to perform nucleophilic substitution, it undergoes a reaction with both primary and secondary alkyl halides. When halides react with triethylamine, the bond between nitrogen and carbon is formed.

In this reaction, the rate of reaction will be slower with secondary alkyl halides due to steric hindrance.  Iodoethane will be more reactive than 1-bromopropane because of the higher electronegativity of iodine which makes it more prone to nucleophilic substitution. Based on the above discussion, the order of increasing rate of reaction with triethylamine is 2-bromopropane < 1-bromopropane < iodoethane.

Therefore, iodoethane is the most reactive of the three alkyl halides, 1-bromopropane is more reactive than  2-bromopropane and 2-bromopropane is the least reactive.
