Question

Write the balanced chemical equations for the following.

Combustion of ethanol

Answer 1

Ethanol:

1. Ethanol has a chemical formula ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$.

Combustion:

1. Ethanol on combustion gives carbon dioxide and water vapors.
2. It is a highly exothermic process.
3. The balanced chemical reaction for the combustion of ethanol is:

$$\begin{gathered} {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{l}\right)+3{\mathrm{O}}_2\left(\mathrm{g}\right)⟶2{\mathrm{CO}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ \mathrm{Ethanol}\mathrm{Oxygen}\mathrm{Carbon}\mathrm{Water} \\ \mathrm{dioxide} \end{gathered}$$
