Chapter 10, Problem 105AP

Interpretation Introduction

Interpretation:

A balanced chemical equation for the combustion reaction of propane is to be written. The volume of carbon dioxide measured at STP is to be calculated, which is produced from the given mass of propane.

Concept Introduction:

A chemical reaction consists of the atoms or molecules that combine with each other to give a product.

Reactants are written in left side of chemical reaction and products are written in right side of chemical reaction.

In a balanced chemical reaction, the number of atoms on both sides of the reaction is the same. Thus, the masses of the reactant are equal to the masses of the product.

STP is standard temperature and pressure.

At STP, temperature is $0^o\text{C}$ and pressure is $1\text{ atm}$.

The volume of carbon dioxide can be calculated as:

${\text{Volume of CO}}_2=\left(\frac{\text{Volume}\text{of}{\text{CO}}_{\text{2}}}{\text{1}\text{mol}{\text{CO}}_{\text{2}}}\right)\text{×}\left(\frac{\text{mol}{\text{CO}}_{\text{2}}}{\text{mol}{\text{C}}_{\text{3}}{\text{H}}_{\text{8}}}\right)\text{×}\left(\frac{\text{given}\text{mass}}{\text{molar}\text{mass}}\right)$
