Question

Write a chemical equation for complete combustion for each of the following:

a) heptane

b) $2-$methyl$-1-$pentene

c) ethylcyclopentane

Short answer

The chemical equations for complete combustion are:

a)${\mathrm{C}}_6{\mathrm{H}}_{12}+9{\mathrm{O}}_2\to 6{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

b)${\mathrm{C}}_6{\mathrm{H}}_{12}+{\mathrm{O}}_2⟶6{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

c)$2{\mathrm{C}}_4{\mathrm{H}}_{10}+13{\mathrm{O}}_2⟶8{\mathrm{CO}}_2+10{\mathrm{H}}_2\mathrm{O}$

Step-by-step solution

Part (a) Step 1: Given information

We have to write the product after the combustion of heptane

Part (a) Step 2: Simplify

The type of reaction in which a fuel is oxidised by reacting with an oxidising agent, releasing heat energy is called combustion reaction.

The balanced equation for the reactant given is:

${\mathrm{C}}_6{\mathrm{H}}_{12}+9{\mathrm{O}}_2\to 6{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

Part (b) Step 1: Given information

We have to write the product after the combustion of$2-$methy$-1-$pentene

Part (b) Step 2: Simplify

The type of reaction in which a fuel is oxidised by reacting with an oxidising agent, releasing heat energy is called combustion reaction.

The balanced equation for the reactant given is:

${\mathrm{C}}_6{\mathrm{H}}_{12}+{\mathrm{O}}_2⟶6{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

Part (c) Step 1: Given information

We have to write the product after the combustion of ethylcyclopentane

Part (c) Step 2: Simplify

The type of reaction in which a fuel is oxidised by reacting with an oxidising agent, releasing heat energy is called combustion reaction.

The balanced equation for the reactant given is:

$2{\mathrm{C}}_4{\mathrm{H}}_{10}+13{\mathrm{O}}_2⟶8{\mathrm{CO}}_2+10{\mathrm{H}}_2\mathrm{O}$
