Question

When hydrogen burns in oxygen water is formed and when water is electrolized the hydrogen and oxygen are produced .waht type of reaction is taking place in first case and second case

Answer 1

Answer:

• Combustion Reaction

• Decomposition Reaction

Explanation:

Combustion Reaction :

The burning of hydrogen gas with oxygen gas to form water molecules is a combustion reaction as it is combustion of hydrogen in the presence of oxygen gas. It can also called a combination reaction of hydrogen and oxygen gas. This reaction results in forming water.

Decomposition Reaction:

Electrolysis of water to form hydrogen gas and oxygen gas is a decomposition reaction as here one molecule breaks to form more than one products. Then it is referred to as decomposition reaction.
