What is the chemical equation?

Electrolysis (splitting) of water.
H20-->
​

it will form hydrogen (H2) and oxygen gas (O2)

Explanation:

here is the solution : -

it's a electrolytic decomposition of water, in which water molecules split apart to form hydrogen and oxygen gas.

here is the balanced chemical equation for the above chemical reaction : -

2 H2O =》2 H2 + O2

hydrogen(H2) and oxygen gas(O2

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
