Question

when hydrogen burns in oxygen water is formed when eater is electrolysed then hydrogen and oxygen are produced . what type of chemical reaction are occured in both the cases​

Answer 1

Explanation:

water is formed,then it is a combination reaction. whenwater is electrolysed intohydrogen and oxygen,then it is a decomposition reaction. n a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases heat.
