Answer:
in this reaction, the ON of Oxygen on H2O is 1 and the oxidation number of Hydrogen is +1, and of oxygen is -2. So oxygen goes through reduction, and hydrogen goes through oxidation. Hence this is a redox reaction. And energy is released during the process. All this fact make this quite complicated reaction. Also, see the covalent bonds are broken, and a new covalent bond is being formed,
Explanation:
The answer is self explanatory.
