Question

Water can stop a combustible substance from burning. give reason

Answer 1

In this case, hydrogen and oxygen are both very reactive, which is why they react together (or 'combust') to form water. The water that is formed is much less reactive, and does not easily react with oxygen, and so will not burn. Because water is so non-reactive, it's interaction with the fire is entirely physical.

Answer 2

Water is formed as a result of the combustion of hydrogen. In simple words, water is what you get when you burn hydrogen. So, water doesn’t burn because, in a way, it has already burned.
