Chapter 11, Problem 34A

(a)

Interpretation Introduction

Interpretation: To determine the reactant and product in the given chemical equation.

Concept Introduction: When more than one chemical species gets combined, they will form a different type of chemical species. This process is named a chemical reaction.

Answer to Problem 34A

• Reactants = Sodium (Na) and Water ( ${\text{H}}_{\text{2}}\text{O}$)
• Products = Hydrogen gas ( ${\text{H}}_{\text{2}}$ ) and Sodium hydroxide ( $\text{NaOH}$)

Explanation of Solution

Hydrogen gas and sodium hydroxide are formed when sodium will react with water.

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

Reactants = Sodium (Na) and Water ( ${\text{H}}_{\text{2}}\text{O}$ )

Products = Hydrogen gas ( ${\text{H}}_{\text{2}}$ ) and Sodium hydroxide ( $\text{NaOH}$ )

(b)

Interpretation Introduction

Interpretation: To determine the reactant and product in the given chemical equation.

Concept Introduction: When more than one chemical species gets combined with each then they will form a different type of chemical species. This process is named a chemical reaction.

Answer to Problem 34A

• Reactants = Carbon dioxide ( ${\text{CO}}_{\text{2}}$ ) and Water ( ${\text{H}}_{\text{2}}\text{O}$)
• Products = Oxygen gas ( ${\text{O}}_{\text{2}}$ ) and Glucose ( ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}$)

Explanation of Solution

In photosynthesis, carbon dioxide and water react to form oxygen gas and glucose.

  ${\text{6CO}}_{\text{2}}{\text{+6H}}_{\text{2}}\text{O}\to {\text{6O}}_{\text{2}}{\text{+C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}$

Reactants = Carbon dioxide ( ${\text{CO}}_{\text{2}}$ ) and Water ( ${\text{H}}_{\text{2}}\text{O}$ )

Products = Oxygen gas ( ${\text{O}}_{\text{2}}$ ) and Glucose ( ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}$ )
