Answer: Option (c) is the correct answer.

Explanation:

A layer above the troposphere and below the mesosphere is known as stratosphere.

This layer of stratosphere contains about 90% concentration of ozone and there is no occurrence of weather in this layer.

The occurrence of ozone in stratosphere makes it warmer.

Therefore, we can conclude that the stratosphere contains the highest concentration of ozone.

A balloon with a volume of 2.0 L is filled with a gas at 3 atmospheres. If the pressure is reduced to 0.5 atmospheres without a

creativ13 [48]

Answer:

V2 = 12 L

Explanation:

Given the following data;

Initial volume = 2L

Initial pressure = 3 atm

Final pressure = 0.5 atm

To find the new volume V2, we would use Boyles' law.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

$PV = K$

$P_{1}V_{1} = P_{2}V_{2}$

Substituting into the equation, we have;

$3 * 2 = 0.5V_{2}$

$6 = 0.5V_{2}$

$V_{2} = \frac {6}{0.5}$

$V_{2} = 12$

V2 = 12L

Therefore, the new volume is 12 Liters.

The combustion method used to analyze for carbon and hydrogen can be adapted to give percentage N by collecting the nitrogen fro

12345 [234]

Answer:

The percentage of N in the compound is 0.5088

Explanation:

Mass of compound = 8.75 mg = 8.75×1000 = 8750 g

Mass of N2 = number of moles of N2 × MW of N2 = 1.59 × 28 = 44.52 g

% of N in the compound = (mass of N2/mass of compound) × 100 = (44.52/8750) × 100 = 5.088×10^-3 × 100 = 0.5088

What pressure is required to compress 196.0 liters of air at 1.83 atmosphere into a cylinder whose volume is 26.0 liters

drek231 [11]

Answer:

P₂ = 13.79 atm

Explanation:

Given data:

Initial volume = 196.0 L

Initial pressure = 1.83 atm

Final volume = 26.0 L

Final pressure = ?

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.83 atm × 196.0 L = P₂× 26.0 L

P₂ = 358.68 atm. L / 26.0 L

P₂ = 13.79 atm
