CAIE IGCSE Chemistry 11.6.2 Combustion of ethanol

Practise recognising ethanol as a fuel and writing balanced equations for complete combustion to form carbon dioxide and water.

Exam points

write the balanced complete combustion equation for ethanol with oxygen
name carbon dioxide and water as the products when ethanol burns in excess oxygen

[Maximum number: 2]

Ethanol, $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$ , belongs to the homologous series called alcohols.

Ethanol is a fuel.

Write the chemical equation for the complete combustion of ethanol.

$\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+3 \mathrm{O}_{2} \rightarrow 3 \mathrm{H}_{2} \mathrm{O}+2 \mathrm{CO}_{2}$

species (1) correct equation (1)
