Chapter 21, Problem 21.58QP

Interpretation Introduction

Interpretation: Percentage by volume of  ${\text{CO}}_{\text{2}}$ in air for the given reaction should be determined.

Concept introduction:

• Balanced chemical equation of a reaction is written according to law of conservation of mass.
• Equation for Number of moles of a substance, from its given mass is,

$\text{Number of moles}\text{=}\frac{\text{Given}\text{mass}}{\text{Molecular}\text{mass}}$

• Mole ratio or molar ratio is the ratio between the amounts in moles of any two compounds involved in the chemical reaction.
• Ideal gas equation is $\text{PV=nRT}$

Where P, V, n, R and T are the pressure, volume, amount of substance, universal gas

Constant and temperature in absolute scale respectively.

• Percent yield of reaction is the ratio of mass of actual yield to the mass of theoretical yield and multiplied with hundred.

To determine: the balanced chemical equations for the given chemical reaction.
