Chapter 8, Problem 8.2TC

Interpretation Introduction

(a)

Interpretation:

Whether the statement “The equation ${\text{C}}_{\text{2}}{\text{H}}_4\text{O}+\text{3}{\text{O}}_{\text{2}}\to \text{2}{\text{CO}}_{\text{2}}+\text{2}{\text{H}}_{\text{2}}\text{O}$ is balanced” is true or false is to be stated.

Concept introduction:

In a balanced chemical equation, all the reactants and products are written with their stoichiometric coefficients and their physical states. The number of atoms of an element on both sides of a balanced chemical equation is equal.

Interpretation Introduction

(b)

Interpretation:

Whether the statement “The equation ${\text{H}}_{\text{2}}+{\text{O}}_{\text{2}}\to {\text{H}}_{\text{2}}\text{O}$ may be balanced by changing it to ${\text{H}}_{\text{2}}+{\text{O}}_{\text{2}}\to {\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$.” is true or false is to be stated.
