Question

The reaction in which hydrogen and oxygen are produced by running an electric current through water is an example of

Answer 1

The answer is electrolysis. This is the chemical reaction that decomposes a substance (usually while in its liquid state) to its components by passing an electric current through it. Electrolysis of water is used to produce hydrogen fuel and also produce oxygen that can be used to supplement breathable air such as in submarines.

Answer 2

Decomposition is the  example  of a  reaction  in  which  hydrogen and oxygen  are  produced  by  running   an  electric current  through  water.

 Decomposition  of   water through  electrolysis  of  water  into   oxygen  and hydrogen   gas  due  an electric  current  passed  through   water.   when an  electric  current  is passed through  water, oxygen   gas is being  produced  at  the anode  and  hydrogen  gas  is produced  at the  cathode.
