Answer:

See explanation

Explanation:

It is possible to generate electricity through a chemical reaction in two ways;

I) use of a voltaic cell where spontaneous chemical processes produce electrical energy.

ii) use of an electrolytic cell where non spontaneous chemical processes produce electrical energy.

The chemical formula of ethane is C2H6

The balanced chemical equation for the combustion of ethane is as follows;

C2H6 + 7/2 O2 ------> 2CO2 + 3H2O
