potential energy and bond formation

In the electrolysis of water we were able to break water into it's component parts. We did this because an electric current through water breaks the bonds holding the atoms together. In test tube "A" we had twice as much gas over the electrode was observed over test tube "B"'s electrode. The gas in "A" when flame tested and splint tested created a pop. The gas in "B" when flame tested and splint tested caused increase in the rate of burning. Using properties of substances chart above determine what was in test tube A.

• Oxygen

• Carbon Dioxide

• Helium

• Hydrogen
