Chapter 5, Problem 5.76E

Interpretation Introduction

Interpretation:

Among the given coefficients, the coefficient of ${\text{O}}_{\text{2}}$ after the following equation ${\text{\_CH}}_{\text{4}}+{\text{\_O}}_{\text{2}}\to {\text{\_CO}}_2+{\text{\_H}}_{\text{2}}\text{O}$ is balanced is to be identified.

Concept Introduction:

The chemical equation is said to be balanced when the number of atoms of chemical species on the reactant side is equal to the number of chemical species on the product side.
