Question

What reaction would the chemical equation 2H2O→2H2+O2 represent?


combustion of water


decomposition of water


replacement of water


formation of water

Answer 1

Answer:

decomposition of water

Explanation:

The reaction will represent the decomposition of water. It usually carried by an electrolytic process in the laboratory.

• Water molecule is broken down into its constituent hydrogen gas and oxygen gas components.
• The breaking down of one compound to give other compounds is decomposition.
• This is not a replacement reaction.
• In decomposition, we often start with a single reactant and results in one or more products.
