Answer:

decomposition of water

Step-by-step 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.
