I have never heard about that,
2H2 + O2 --> 2H2O can be done, but I'm doubt about the answr of your question...

Your formula is OK.
(A SMALL amount of sulfuric acid will assist the dissociation)
You need a water container ..preferably glass... (and water of course). 2 metal electrodes and a 6 volt battery.
The electrodes (conductive metal) ..are connected to the battery ..one to the positive side and the other to the negative side. The electrodes are placed into the water bath about 10cm apart.
The Cathode is the negative electrode
The Anode is the positive electrode
As the electricity flows through the water the water begins to give off H(+) ions (cations) which go to the cathode and O(-) ions (anions) go to the anode..
The Hydrogen gas will come off the Anode and the Oxygen gas from the Cathode.

It can be done by a process called electrolysis.
It's an experiment I did in high school chemistry class. Pretty simple stuff.
But don't think it's a great source of cheap energy, because it requires more electrical energy to electrolyze water than you get back when you burn the hydrogen to reform water.

That is the balanced equation of water decomposition. Yes it is correct. The hydrogen and oxygen atoms are diatomic, so there are ALWAYS two atoms when they are alone. So this creates an extra oxygen, which is why we add coefficients in the front to balance both sides to have the same number of atoms.
