Chapter 8, Problem 8.85QP

(a)

Interpretation Introduction

Interpretation: for the given reaction, the balanced equation and the mass of product hydrogen gas obtained from $\text{2}\text{.84}\text{×}{\text{10}}^{\text{3}}\text{kg}$ of propane are needed to be determined.

Concept introduction:

• Balanced chemical equation of a reaction is written according to law of conservation of mass.
• Limiting reactant: limiting reactant is a reactant, which consumes completely in the chemical reaction. The quantity of the product depends on this limiting reactant, it can be determined with the help of balanced chemical equation for the reaction.
• Equation for Number of moles of a substance, from its given mass is,

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