Question

A) what happens when 1) ethanol burns in air 2) ethanol reacts with sodium metal

Answer 1

When ethanol is burnt, it reacts with oxygen and produces water and carbon dioxide. The chemical equation of the combustion of ethanol is:

CH_3CH_2OH + 3O_2 -> 2CO_2 + 3H_2O

c2h5oh  + na ----> c2h5ona  + h2

Answer 2

Ans.a   CH3CH2OH + 3O2 ---------->  2CO2 +  3H2O

Ethanol burns in the air to give carbon dioxide and water.

Ans.b   2CH3CH2OH + 2Na -------------->  2CH3CH2NA +  H2
