When electricity is passed through water, what kind of chemical reaction occurs?

Question

Accepted Answer

1. Passing electricity through water is called electrolysis; it causes water molecules to break down into hydrogen and oxygen gas.

2. The chemical equation is: $2\mathrm{H}_2\mathrm{O}(l) \rightarrow 2\mathrm{H}_2(g) + \mathrm{O}_2(g)$.

3. A single compound (water) is being broken into simpler substances (H2 and O2), which is the definition of a decomposition reaction. Therefore the correct choice is (1) Decomposition.
