Question

reason for reaction between hydrogen and oxygen to form water is a chemical reaction

Answer 1

its a ionic compound
to attain inert gas configuration
they combine

H give 2 electron,
O get 2 electron

now,they are stable in
configuration

Answer 2

We know that all the elements react to complete their octate or to become stable.
We also know that both hydrogen and oxygen having incomplete octate and hence they react to form water by chemical reactions.
