Step-by-Step Solution

Verified

Answer

(a) The balanced chemical equation for the complete combustion of ethane is,

$2 C_{2} H_{6} + 7 O_{2} \to C O_{2} + 6 H_{2} O$ ,

(b) The balanced chemical equation for the complete combustion of cyclopropane is,

$2 C_{3} H_{6} + 9 O_{2} \to 6 C O_{2} + 6 H_{2} O$ ,

$2 C_{8} H_{18} + 25 O_{2} \to 16 C O_{2} + 18 H_{2} O$

1Part(a) Step 1:Given information

We have been given,

The balanced chemical equation for the complete combustion of ethane.

2Part(a) Step 2:Explanation

Combustion is a chemical reaction in which a hydrocarbon combines with oxygen to produce carbon dioxide and water.

The hydrocarbon combustion reaction is an exothermic reaction that releases heat energy. A negative enthalpy change $(∆ H)$ value is also present in the reaction.

$2 C_{2} H_{6} + 7 O_{2} \to C O_{2} + 6 H_{2} O$ .

3Part(b) Step 1:Given information

We have been given,

The balanced chemical equation for the complete combustion of cyclopropane.

4Part(b) Step 2:Explanation

Combustion is a chemical reaction in which a hydrocarbon combines with oxygen to produce carbon dioxide and water.

The hydrocarbon combustion reaction is an exothermic reaction that releases heat energy. A negative enthalpy change $(∆ H)$ value is also present in the reaction.

$2 C_{3} H_{6} + 9 O_{2} \to 6 C O_{2} + 6 H_{2} O$ .

5Part(c) Step 1:Given information

We have been given,

The balanced chemical equation for the complete combustion of $2, 3 - d i m e t h y l h e x a n e .$

6Part(c) Step 2:Explanation

Combustion is a chemical reaction in which a hydrocarbon combines with oxygen to produce carbon dioxide and water.

The hydrocarbon combustion reaction is an exothermic reaction that releases heat energy. A negative enthalpy change $(∆ H)$ value is also present in the reaction.

$2 C_{8} H_{18} + 25 O_{2} \to 16 C O_{2} + 18 H_{2} O$
