Question

Write the balanced chemical equation for the complete combustion of each of the following hydrocarbons found in gasoline:

a) decane

b) cyclohexane

c) toluene

Short answer

The balanced chemical equation for the complete combustion of each of the following hydrocarbons found in gasoline:

a)${\mathrm{C}}_{10}{\mathrm{H}}_{22}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})\to {\mathrm{CO}}_2(\mathrm{g})+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$

b)${\mathrm{C}}_6{\mathrm{H}}_{12}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})\to {\mathrm{CO}}_2(\mathrm{g})+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$

c)${\mathrm{C}}_7{\mathrm{H}}_8(\mathrm{g})+9{\mathrm{O}}_2(\mathrm{g})\to 7{\mathrm{CO}}_2(\mathrm{g})+4{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$

Step-by-step solution

Part (a) Step 1: Given information

We have to give the product for complete combustion of given compound.

Part (a) Step 2: Explanation

As we know, that organic compounds contain carbon and hydrogen. The burning raection between the hydrocarbon and oxygen is called combustion.

The balanced chemical equation for the complete combustion is:

${\mathrm{C}}_{10}{\mathrm{H}}_{22}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})\to {\mathrm{CO}}_2(\mathrm{g})+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$

Part (b) Step 1: Given information

We have to give the product for complete combustion of given compound.

Part (b) Step 2: Explanation

As we know, that organic compounds contain carbon and hydrogen. The burning raection between the hydrocarbon and oxygen is called combustion.

The balanced chemical equation for the complete combustion is:

${\mathrm{C}}_6{\mathrm{H}}_{12}(\mathrm{g})+{\mathrm{O}}_2(\mathrm{g})\to {\mathrm{CO}}_2(\mathrm{g})+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$

Part (c) Step 1: Given information 

We have to give the product for complete combustion of given compound.

Part (c) Step 2: Explanation

As we know, that organic compounds contain carbon and hydrogen. The burning raection between the hydrocarbon and oxygen is called combustion.

The balanced chemical equation for the complete combustion is:

${\mathrm{C}}_7{\mathrm{H}}_8(\mathrm{g})+9{\mathrm{O}}_2(\mathrm{g})\to 7{\mathrm{CO}}_2(\mathrm{g})+4{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$
