Interpretation:
The reason for equation to be balanced before calculating the volumes of gases involved needs to be explained.
Concept introduction:
Stoichiometric concepts are involved to determine the volumes of gases involved.
Answer to Problem 79A
Because stoichiometry coefficients are the ratios among gas volume in the balanced chemical equation.
Explanation of Solution
A balanced chemical equation gives the quantitative relationship of volumes between various reactants and products.
Thus it is necessary to balance a chemical equation before using relative gas volume relationships.
