Chapter 8, Problem 1E

Consider the following particulate-level representation of a chemical equation:

The white spheres represent hydrogen atoms, the black sphere represents a carbon atom, and the red spheres represent oxygen atoms. (a) Write a balanced chemical equation representing this reaction. (b) Write a word description of the reaction on the particulate and molar levels.

Interpretation Introduction

(a)

Interpretation:

The balanced chemical equation representing the given particulate–level reaction 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.

Answer to Problem 1E

The chemical equation that represents the given particulate–level reaction is shown below.

$\text{CO}+{\text{H}}_2\text{O}\to {\text{CO}}_2+{\text{H}}_2$

Explanation of Solution

The given reaction is,

Figure 1

The black sphere represents carbon atom, white spheres represents hydrogen atom and red sphere represents oxygen atom. The chemical equation that represents the given particulate–level reaction is,

$\text{CO}+{\text{H}}_2\text{O}\to {\text{CO}}_2+{\text{H}}_2$

The given reaction is balanced as the number of atoms on both the sides of equation is same.

Conclusion

The chemical equation that represents the given particulate–level reaction is,

$\text{CO}+{\text{H}}_2\text{O}\to {\text{CO}}_2+{\text{H}}_2$
