c. dimethylpropane

Step-by-Step Solution

Verified

Answer

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

$2 C_{6} H_{14} + 19 O_{2} \to 12 C O_{2} + 7 H_{2} O$ .

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

$2 C_{5} H_{10} + 15 O_{2} \to 10 C O_{2} + 10 H_{2} O$ .

$C_{5} H_{12} + 8 O_{2} \to 5 C O_{2} + 6 H_{2} O$ .

1Part(a) Step 1:Given information

We have been given,

The balanced chemical equation for the complete combustion of hexane.

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.

$2 C_{6} H_{14} + 19 O_{2} \to 12 C O_{2} + 7 H_{2} O$

3Part(b) Step 1:Given information

We have been given,

The balanced chemical equation for the complete combustion of cyclopentane.

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.

$2 C_{5} H_{10} + 15 O_{2} \to 10 C O_{2} + 10 H_{2} O$ .

5Part(c) Step 1:Given information

We have been given,

The balanced chemical equation for the complete combustion of dimethylpropane.

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.

$C_{5} H_{12} + 8 O_{2} \to 5 C O_{2} + 6 H_{2} O$ .
