Chapter 11.2, Problem 19SP

(a)

Interpretation Introduction

Interpretation:

To determine the balance combustion equation for glucose.

Concept Introduction: When a chemical combines with oxygen gas, it produces a combustion reaction that releases energy in the manner of heat and light.

Answer to Problem 19SP

The complete combustion reaction of glucose will be ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}{\text{(s)+6O}}_{\text{2}}\text{(g)}\to {\text{6CO}}_{\text{2}}{\text{(g)+6H}}_{\text{2}}\text{O}$ .

Explanation of Solution

The complete combustion of glucose will give carbon dioxide and water. Therefore, the balanced chemical equation can be written as:

  ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}{\text{(s)+6O}}_{\text{2}}\text{(g)}\to {\text{6CO}}_{\text{2}}{\text{(g)+6H}}_{\text{2}}\text{O}$

(b)

Interpretation Introduction

Interpretation: To determine the balance combustion for acetone.

Concept Introduction: When a chemical combines with oxygen gas, it produces a combustion reaction that releases energy in the manner of heat and light.

Answer to Problem 19SP

The complete combustion reaction of acetone will be ${\text{C}}_{\text{3}}{\text{H}}_{\text{6}}{\text{O(l)+4O}}_{\text{2}}\text{(g)}\to {\text{3CO}}_{\text{2}}{\text{(g)+3H}}_{\text{2}}\text{O}$

Explanation of Solution

When acetone will react with oxygen then it will give carbon dioxide and water. The complete combustion of acetone will give carbon dioxide and water. Therefore, the balanced chemical equation can be written as:

  ${\text{C}}_{\text{3}}{\text{H}}_{\text{6}}{\text{O(l)+4O}}_{\text{2}}\text{(g)}\to {\text{3CO}}_{\text{2}}{\text{(g)+3H}}_{\text{2}}\text{O}$

(c)

Interpretation Introduction

Interpretation: To determine the balance combustion reaction for pentanal.

Concept Introduction: When a chemical combines with oxygen gas, it produces a combustion reaction that releases energy in the manner of heat and light.

Answer to Problem 19SP

The complete combustion reaction of pentanal will be ${\text{C}}_{\text{5}}{\text{H}}_{\text{11}}\text{OH(l)+}\frac{\text{15}}{\text{2}}{\text{O}}_{\text{2}}\to {\text{5CO}}_{\text{2}}{\text{(g)+6H}}_{\text{2}}\text{O}$

Explanation of Solution

When pentanal will react with oxygen then it will give carbon dioxide and water. The complete combustion of pentanol will give carbon dioxide and water. Therefore, the balanced chemical equation can be written as:

  ${\text{C}}_{\text{5}}{\text{H}}_{\text{11}}\text{OH(l)+}\frac{\text{15}}{\text{2}}{\text{O}}_{\text{2}}\to {\text{5CO}}_{\text{2}}{\text{(g)+6H}}_{\text{2}}\text{O}$
