In like manner, represent particle diagrams that account for the fact that one volume of hydrogen combines with one volume of chlorine to form hydrogen chloride. What do you suppose is the formula of hydrogen chloride?

Answers

Answer 1

Answer:

According to Avogadro's law which states that equal volumes of all gases under the same condition of temperature and pressure contain equal number of molecules. Therefore, one molecule of hydrogen reacts with one molecule of chlorine to yield two molecules of hydrogen chloride.

The formula of hydrogen chloride is HCl

The particle diagram is found in the attachment below.

Explanation:

The reaction between hydrogen and chlorine to form hydrogen chloride is represented by the equation below

H₂(g) + Cl₂(g) ---> 2HCl(g)

In the reaction equation above, one mole (or one volume) of diatomic hydrogen gas reacts with one mole (or one volume) of diatomic chlorine gas to form two moles (or two volumes) of hydrogen chloride gas. This is in accordance with Avogadro's law which states that equal volumes of all gases under the same condition of temperature and pressure contain equal number of molecules.

Answers

Answer:

Octahedral

Explanation:

The idea of hybridization is a valence bond concept introduced by Linus Pauling and soon became an important explanation for the structure of molecules even in coordination chemistry.

Hybridization involves the mixing of orbitals of appropriate energy to form a new set of orbitals that are more suitable for bonding with ligands.

When one s, two d and three p orbitals are hybridized in complex formation, octahedral complexes are formed.

10 mL of a 0.65 M KMnO4 solution is diluted to a concentration of 0.055 M. What is the final volume of the diluted solution?

a. 20.0 mL
b. 0.846 mL
c. 108 ml
d. 118 ml

Answers

Answer:

118 mL

Explanation:

We can easily calculate the final volume of the solution (V₂) by applying the following mathematical expression:

V₁ x C₁ = V₂ x C₂

⇒ V₂ = V₁ x C₁/C₂

Given:

V₁ = 10 mL

C₁ = 0.65 M

C₂ = 0.055 M

We replace the data in the mathematical expression to calculate V₂:

V₂ = V₁ x C₁/C₂ = 10 ml x (0.65 M)/ (0.055 M) = 118.18 mL ≅ 118 mL

A sample of radioactive material starts with 80 grams. After 3 half-lives have passed, how much radioactive sample remains?

Answers

Answer:

After 3 half lives 10 g of radio active material left.

Explanation:

Given data:

Total amount of radio active material = 80 g

Amount left after 3 half lives = ?

Solution:

At time zero = 80 g

At first half life = 80 g/2 = 40 g

At 2nd half life = 40 g/2 = 20 g

At 3rd half life = 20 g/2 = 10 g

Thus, after 3 half lives 10 g of radio active material left.

Part A: You are given a beaker containing a solution of an enzyme that hydrolyzes adenosine triphosphate (ATP) while it generates a lot of heat. You add a substantial amount of the sodium salt of ATP, and you measure the temperature of the beaker, and determine that nothing is happening. The enzyme is not performing the reaction. What is a reasonable chemical to add to the solution to get the enzyme to proceed with the hydrolysis of adenosine triphosphate?
Sulfur oxide,
Iron chloride,
magnesium chloride,
or add more sodium ATP.
Part B: You are investigating the reduction of oxygen that is performed by cytochrome c oxidase. As you start the reaction in a slightly acidic aqueous buffer with 2 mM Cu2SO4 and bubbling oxygen into the buffer. As the reaction proceeds, the solution slowly turns blue, what is happening?
a) Ozone is formed. This causes the solution to turn blue.
b) The copper is getting oxidized from Cu+ to Cu2+ and turns blue.
c) The cytochrome c oxidase protein is decomposing down to a blue product.
d) The pH of the solution is changing. Cu2SO4 is a pH indicator that turns blue when a solution becomes basic.
Part C: In the previous reaction, if you add a small amount of cyanide before adding the
Cu2SO4, the solution does not turn blue. What is a reasonable explanation?
a) The cyanide ion displaces the copper ions in the cytochrome c oxidase and stops the redox reaction.
b) The cyanide ion keeps the pH of the solution high. So the Cu2SO4 pH indicator does not show the decrease in pH.
c) The cyanide ion prevents the formation of ozone.

Answers

Answer:

1) magnesium chloride

2) b) The copper is getting oxidized from Cu+ to Cu2+ and turns blue.

Explanation:

The work published by David N. Frick, Sukalyani Banik, and Ryan S. Rypma in J Mol Biol. 2007 Jan 26; 365(4): 1017–1032 clearly shows that divalent metal ions of group 2 such as Mg^2+ play an important role in ATP hydrolysis. Addition of EDTA decreased the rate of hydrolysis of ATP (due to sequestration of the divalent ion of group 2) indicating an active participation of divalent ions in the process.

2) The copper I ion is colourless because it is a d^10 specie. However, when it is oxidized to Cu^2+, a blue colour appears in the solution.

What mass (in grams) of silver contains the same number of atoms as 5.59 grams of sulfur?

Answers

Answer:

18.84 g of silver.

Explanation:

We'll begin by calculating the number atoms present in 5.59 g of sulphur. This can be obtained as follow:

From Avogadro's hypothesis,

1 mole of sulphur contains 6.02×10²³ atoms.

1 mole of sulphur = 32 g

Thus,

32 g of sulphur contains 6.02×10²³ atoms.

Therefore, 5.59 g of sulphur will contain = (5.59 × 6.02×10²³) / 32 = 1.05×10²³ atoms.

From the calculations made above, 5.59 g of sulphur contains 1.05×10²³ atoms.

Finally, we shall determine the mass of silver that contains 1.05×10²³ atoms.

This is illustrated below:

1 mole of silver = 6.02×10²³ atoms.

1 mole of silver = 108 g

108 g of silver contains 6.02×10²³ atoms.

Therefore, Xg of silver will contain 1.05×10²³ atoms i.e

Xg of silver = (108 × 1.05×10²³)/6.02×10²³

Xg of silver = 18.84 g

Thus, 18.84 g of silver contains the same number of atoms (i.e 1.05×10²³ atoms) as 5.59 g of sulfur

Answer:

35.453 amu.

Explanation:

From the question given above, the following data were obtained:

Isotope A (Cl–35):

Abundance (A%) = 75.77%

Mass of A = 34.969 amu

Isotope B (Cl–37):

Abundance (B%) = 24.23%

Mass of B = 36.966 amu

AVERAGE atomic mass of Cl =?

The average atomic mass of Cl can be obtained as follow:

Average = [(Mass of A × A%)/100] + [(Mass of B × B%)/100]

Average = [(34.969 × 75.77)/100] + [(36.966 × 24.23)/100]

Average = 26.496 + 8.957

Average atomic mass of Cl = 35.453 amu.

A sample of an unknown compound is vaporized at 150.°C . The gas produced has a volume of 960.mL at a pressure of 1.00atm , and it weighs 0.941g . Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Round your answer to 3 significant digits.

Answers

Answer:

the  molar mass of the compound is  34.0 g /mol

Explanation:

The computation of the molar mass of the compound is as follows:

As we know that

PV = nRT

n = mass ÷ MW

PV = mRT ÷ MW

It can be rearrange as

MW = mRT ÷ (PV)

MW = (0.941)(0.082)(150 + 273) ÷ (1 × 0.96)

= 33.99g/mol

= 34.0 g /mol

Hence, the  molar mass of the compound is  34.0 g /mol

A gas sample occupies 4.39 L at 44 ºC. What will be the new volume, using Charles’ Law, if the temperature decreases to 25 ºC?

Answers

Hi there! :)

[tex]\large\boxed{x = 2.49 L}[/tex]

Use the proportion for Charles' Law where:

[tex]\frac{v_{1}}{t_{1}}= \frac{v_{2}}{t_{2}}[/tex]

v1 = initial volume

t1 = initial temperature

v2 = final volume

v2 = final temperature

Substitute in the given values into the proportion:

v1 = 4.39 L

t1 = 44° C

t2 = 25°C

v2 = x L

Set up the proportion:

[tex]\frac{4.39}{44} = \frac{x}{25}[/tex]

Cross multiply:

[tex]25 * 4.39 = 44x\\\\109.75 = 44x\\\\x = 2.49 L[/tex]

Answer:

The new volume will be approximately 2.49 L.

Explanation:

We are given that a gas sample occupies 4.39 L at 44° C.

We are also given that we are going decrease the temperature to 25° C.

Charles' Law has a formula which shows the relationship between the volumes of a samples and the temperatures of the samples.

The proportion is shown as:

[tex]\displaystyle \bullet \ \ \ \frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex],

where V₁ and V₂ are the initial and final volume respectively and T₁ and T₂ are the initial and final temperature respectively.

This proportion can be used to determine what our unknown is. We need to know the final volume.

[tex]\displaystyle \frac{4.39 \ \text{L}}{44 \ \text{C}} = \frac{\text{x}}{25 \ \text{C}}\\\\\\\frac{4.39}{44} = \frac{x}{25}\\\\\\4.39 \times 25 = 44 \times x\\\\\\44x = 109.75\\\\\\\frac{44x}{44}=\frac{109.75}{44}\\\\\\x = 2.49432 \approx \boxed{2.49 \ \text{L}}[/tex]

Therefore, if we reduce the temperature to 25 °C, we will be reducing the volume of the substance to 2.49 L.


A solution has a pH of 11.75. Calculate the [H:0*] of the solution

Answers

The [H₃0⁺] of the solution : 1.778  x 10⁻¹² M

Further explanation  

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.  

pH = - log [H⁺]  

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.  

A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.  

pH of solution = 11.75

the [H₃0⁺] of the solution :

[tex]\tt pH=-log[H_3O^+]\\\\11.75=-log[H_3O^+]\\\\(H_3O^+]=10^{-11.75}=1.778\times 10^{-12}[/tex]

Percent yield is very important in terms of money. The higher the percent yield, the more of a product you can make. If you are working for a drug company and your theoretical yield is 120 kg, but you actually made 105 kg, what is your percent yield?
A. 8.75%
B. 114%
C. 87.50%
D. 15.00%

Answers

Answer:

87.5 %

Explanation:

Step 1: Given data

Theoretical yield: 120 kgReal yield: 105 kg

Step 2: Calculate the percent yield

When working with chemical reactions, we can determine the efficience in obtaining a product measuring the percent yield. The theoretical yield is the maximum amount of product that we could obtain according to the stoichiometry, whereas the real yield is the amount of product that we actually obtain when we carry out the process. We can calculate the percent yield usign the following expression.

%yield = real yield / theoretical yield × 100%

%yield = 105 kg / 120 kg × 100%

%yield = 87.5 %
