# How can I seperate water into hydrogen gas and oxygen gas?

Jul 13, 2017

See below.

#### Explanation:

The reaction you want to undergo is the decomposition of water:

$2 \text{ H"2"O" -> 2" H2" + "O} 2$

Basically, you are using decomposition, or the breaking down of molecules, to break down two water molecules into 2 molecules of Hydrogen gas and one molecule of Oxygen gas.

I hope that helps!
