Answer 1

Answer:

In the first case, the two elements, hydrogen and oxygen, combine to form a single compound hence it is a combination reaction. In the second case, a decomposition reaction takes place as a single compound, i.e. water, splits up to form two simple substances-hydrogen and oxygen. This decomposition reaction takes place by the action of electricity.
