Chapter 11.1, Problem 6SP

(a)

Interpretation Introduction

Interpretation: To determine the balanced chemical reactions.

Concept Introduction: When the count of atoms in both directions of the chemical reaction will be identical, then it will be referred to as a balanced chemical reaction.

Answer to Problem 6SP

The balanced chemical reaction will be:

  ${\text{Ca(OH)}}_{\text{2}}\text{+}{\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\to {\text{CaSO}}_{\text{4}}\text{+}{\text{2H}}_{\text{2}}\text{O}$

Explanation of Solution

When calcium hydroxide is reacted with sulfuric acid, then it will form calcium sulfate and water. Its balanced chemical reaction can be written as:

  ${\text{Ca(OH)}}_{\text{2}}\text{+}{\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\to {\text{CaSO}}_{\text{4}}\text{+}{\text{2H}}_{\text{2}}\text{O}$

(b)

Interpretation Introduction

Interpretation: To determine the balanced chemical reactions.

Concept Introduction: When the count of atoms in both directions of the chemical reaction will be identical, then it will be referred to as a balanced chemical reaction.

Answer to Problem 6SP

The balanced chemical reaction will be:

  $\text{2Na}+{\text{2H}}_{\text{2}}\text{O}\to \text{2NaOH}+{\text{H}}_2$

Explanation of Solution

When sodium is reacted with water, then it will form sodium hydroxide and hydrogen. Its balanced chemical reaction can be written as:

  $\text{2Na}+{\text{2H}}_{\text{2}}\text{O}\to \text{2NaOH}+{\text{H}}_2$
