Chapter 7: Q. 7.78 (page 250)

Fatty acids undergo reaction with oxygen gas and form gaseous carbon dioxide and liquid water when utilized for energy in the body.
(a)Write and balance the equation for the combustion of the fatty acid aqueous capric acid $C_{10} H_{20} O_{2}$
(b) Write and balance the equation for the combustion of the fatty acid aqueous myristic acid, $C_{14} H_{28} 0_{2}$

Short Answer

Expert verified

(a) The balance equation for the combustion of the fatty acid aqueous capric acid is : $C_{10} H_{20} O_{2} + 14 O_{2} \to 10 C O_{2} + 10 H_{2} O$

(b) The balance equation for the combustion of the fatty acid aqueous myristic acid is :

$C_{14} H_{28} O_{2} + 20 O_{2} \to 14 C O_{2} + 14 H_{2} O$

Step by step solution

01

Part (a) Step 1: Given Information

We need to Write and balance the equation for the combustion of the fatty acid aqueous capric acid $C_{10} H_{20} O_{2}$

02

Part (a) Step 2: Explanation

The balance equation for the combustion of the fatty acid aqueous capric acid is :

$C_{10} H_{20} O_{2} + 14 O_{2} \to 10 C O_{2} + 10 H_{2} O$

03

Part (b) Step 1: Given Information

We need to Write and balance the equation for the combustion of the fatty acid aqueous myristic acid, $C_{14} H_{28} 0_{2}$

04

Part (b) Step 2: Explanation

The balance equation for the combustion of the fatty acid aqueous myristic acid is :

$C_{14} H_{28} O_{2} + 20 O_{2} \to 14 C O_{2} + 14 H_{2} O$
