Ответ:
A) Decomposing water requires high activation energy
Explanation:
The sun is a renewable resource, because the solar energy we use is less than the solar energy being created. Decomposing water produces hydrogen gas and oxygen gas, which aren't toxic. The oxygen is used in the combustion of the hydrogen gas. However, splitting water molecules into hydrogen and oxygen takes a lot of energy.
