Chapter 21, Problem 21.22QP

Interpretation Introduction

Interpretation: The kilograms of ozone required to compensate the fallen amount ozone in given period of time should be determined using the given equation.

Concept Introduction:

Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth.

The earth atmosphere consists of layers such as thermosphere, mesosphere, stratosphere and troposphere depending on the temperature and its composition.

Stratosphere:

It is found below the mesosphere layer in which the concentration of ozone and other gases are high. The increasing temperature for this layer with respect to increasing height is due to the presence of high concentration of ozone and other gases in it.

The increased temperature is due to the response of UV radiation from sun and hence ozone is formed due to this reaction and the use of ozone is that it prevents the UV radiation from the sun which is actually harmful.

Balanced Equation: A chemical reaction is considered as balanced equation if all the number of atoms, the charge and the mass of elements on both reactant and the product side are equal in the reaction.

Moles: It is the number of particles present in the given specific substance. The formula used to identify the moles present in given mass of a compound is as follows,

$\text{x}\text{moles}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{sample}}{\text{Molecular}\text{mass}\text{of}\text{the}\text{sample}}$

Molar mass: It is the total mass of the substance including all the number and the mass of the elements present in substance

To determine: The amount of ozone needed for compensation of degraded ozone and the energy required to accomplish for the given conversion should be determined.
