Question

Name the product formed in the reaction when ethene burns in air.

Answer 1

Definition of combustion reaction:

• A combustion reaction occurs when a substance combines with oxygen gas and produces energy in the form of light and heat.
• When Ethene$\left({\mathrm{C}}_2{\mathrm{H}}_4\right)$ burns in the air, it generates Carbon dioxide and water liberating a large amount of heat This is a combustion reaction.

$\underset{\mathrm{Ethene}}{{\mathrm{C}}_2{\mathrm{H}}_4\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{3{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{2{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}+\mathrm{Heat}$
