Chapter 3, Problem 3.85QP

(a)

Interpretation Introduction

Interpretation:

The given reaction representing combustion of propane in air has to be balanced.

Concept Introduction:

Balanced Chemical equation:

A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.

(b)

Interpretation Introduction

Interpretation:

The amount of ${\text{CO}}_{\text{2}}$ produced by burning $\text{3}\text{.65 moles}$ of propane in the given reaction has to be calculated.

Concept Introduction:

Amount of substance:

$\text{Grams of the substance = moles of the substance }\times \frac{\begin{array}{l}\text{ molar mass of }\\ \text{substance in grams}\end{array}}{\text{ one mole}}$
