can somebody help me name this organic compound!!​

Answer:

Boyle's Law is a relationship between pressure and volume. In this relationship, pressure and volume have an inverse relationship when temperature is held constant. If there is a decrease in the volume there is less space for molecules to move and therefore they collide more often, increasing the pressure.

Explanation:

Answer:

A. compound (NaCl)

B. element (note: it should be Ar. AR is not an element or compound.)

c. compound (CH4)

d. element (O2)

e. element (Cl)

Explanation:

Element is single and by its self. A compound is multiple elements put together.

Answer: Volume =  50.0 mL in liters : 50.0 / 1000 = 0.05 L

n = M x V

n = 0.20 x 0.05

n = 0.01 moles of solute

Explanation:

The number of moles of solute are present in 50.0 mL of 0.20 M of KNO₃ solution is 0.01 moles.

Moles will be calculated by using the molarity formula because molarity is define as the no. of moles of solute present in per liter of the solution as:

M = n/V, where

M = molarity of KNO₃ = 0.2 M

V = volume of solution = 50mL = 0.05L

Moles will be calculated as:

n = (0.2)(0.05) = 0.01 moles

Hence required moles are 0.01 moles.

Answer:

Reliability. When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable. Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable.

Gamma-ray photons have the highest energy in the EMR spectrum and their waves have the shortest wavelength.

Answer:

The pH is 1.08,  being an acid pH

Explanation:

pH is a parameter used to measure the degree of acidity or alkalinity of a substance. The pH scale ranges from 0 to 14. Values ​​less than 7 indicate the acidity range and those greater than 7 indicate alkalinity or basicity. Value 7 is considered neutral. Mathematically, pH is the negative logarithm of the molar concentration of hydrogen or proton ions (H⁺) or hydronium ions (H₃O⁺).

pH= - log [H⁺]= - log [H₃O⁺]

A strong acid is an acid that completely dissociates into hydrogen ions and anions in solution. This implies that the initial concentration of acid is equal to the final concentration of H₃O⁺. This occurs with acid HCl.

So,  pH is calculated as:

pH= - log (0.083)

pH= 1.08

The pH is 1.08,  being an acid pH

Answer:

ozone (O3): inorganic

methane (CH4): organic

aluminum hydroxide (Al(OH)3): inorganic

butane (C4H10): organic

carbon monoxide (CO): inorganic

Explanation:

An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. Some simple compounds that contain carbon are often considered inorganic. Examples of inorganic compounds include carbon monoxide , carbon dioxide , carbonates, carbides , cyanides, cyanates, and thiocyanates. Most of these compounds are normal parts of mostly organic systems, including living organisms. When a chemical substance is classified as inorganic, it does not necessarily mean that it does not occur within

living things.

Organic compounds typically contain the carbon-hydrogen bonds. The carbon atoms often catenate and most organic substances occur in living systems and are products of biochemical reactions in living organisms. However, organic substances can also be synthetic and can be prepared in the laboratory.

A landslide can be defined as a mass movement of material (e.g., rocks), which moves down a steep slope. A geologist is an expert that studies SLOW-MOVING landslides on a geological scale.

Landslides can occur suddenly or more slowly over long periods of time.

On a geological scale, landslides occur slowly so they are imperceptible to humans.

A geologist is a professional who investigates landslides on a geological scale, which is coarse on a human time-frame.

In conclusion, a geologist is a professional who investigates SLOW-MOVING landslides on a geological scale.

Answer:

2.888mm needs for the reaction

Answer:

V = 513.36m/s

Explanation:

Temperature (T) = 25°C = (25 + 273.15) = 298.15K

Speed (V) = 1.92*10³m/s

According to kinetic theory of gases, the speed (v) of a molecule is

V= √(3RT / M)

V = speed or velocity

R = ideal gas constant = 0.082J/mol.K

T = temperature of the gas

M = molar mass

Molar mass of hydrogen molecule = 2.0g/mol

Molar mass of Nitrogen molecule = (2×14.0) = 28.0g/mol

Since they're in the same temperature

V1 / V2 = √(M2 / M1)

1.92×10³ / V2 = √(28 / 2)

1.92×10³ / V2 = √(14)

1.92*10³ / V2 = 3.74

1.92*10³ = 3.74V2

V2 = 1920 / 3.74

V2 = 513.36m/s

The velocity of Nitrogen molecule is 513.36m/s

Answer: 16700 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

[tex]Q=m\times c\times \Delta T[/tex]

Q = Heat absorbed = ?

m = mass of sand = 2 kg

c = heat capacity = [tex]835J/kg^0C[/tex]

Initial temperature  = [tex]T_i[/tex] = [tex]40^0C[/tex]

Final temperature= [tex]T_f[/tex]  = [tex]50^0C[/tex]

Change in temperature ,[tex]\Delta T=T_f-T_i=(50-40)^0C=10^0C[/tex]

Putting in the values, we get:

[tex]Q=2kg\times 835J/kg^0C\times 10^0C[/tex]

[tex]Q=16700J[/tex]

16700 J of energy must be added to a 2-kilogram pile of it to increase its temperature from 40°C to 50°C

Answer: The reaction of one mole of oxygen [tex](O_2)[/tex] releases 445 kJ of energy.

Explanation:

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be positive.

[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(l)[/tex]  [tex]\Delta H=-890kJ[/tex]

on halving the reaction, enthalpy also becomes half

[tex]\frac{1}{2}CH_4(g)+O_2(g)\rightarrow \frac{1}{2}CO_2(g)+H_2O(l)[/tex]  [tex]\Delta H=-445kJ[/tex]

Thus The reaction of one mole of oxygen [tex](O_2)[/tex] releases 445 kJ of energy.

Answer:

the number of orange candies divided by total number of candies

the mass of orange candies divided by total mass of candies

Explanation:

The two correct options that are appropriate to describe the concentration of orange candies would be the number of orange candies divided by total number of candies and the mass of orange candies divided by total mass of candies.

The concentration of a substance can be described as the fraction of that substance in a particular mix of substances.

In term of number, the concentration of a substance in a mix of substances can be expressed as the number of that substance divided by the total number of substances in the mix.

In term of mass, the concentration of a substance in a mix of substances can be expressed as the mass of that substance divided by the total mass of the mix.

Answer:

55×10^-26 J

Explanation:

We can calculate the energy of the wave from

E= hc/λ

Where

h= Planks constant = 6.6×10^-34 Is

c= speed of light = 3×10^8 ms-1

λ= wavelength of the wave = 0.36 metres

Recall that cell phone use radio waves which belong to the electromagnetic spectrum hence it must possess the speed of light.

E= 6.6×10^-34 × 3×10^8/ 0.36

E= 55×10^-26 J

Hence the energy possessed by 0.36 meters wavelength radio waves is 55×10^-26 J
