Explanation of the Reaction

When an electric current flows through water, the chemical equation is H₂O → H₂ + O. We know there were two different gases that formed because when oxygen burns, fire grows brighter, while when hydrogen burns, fire goes out with a "pop." Because of this, and the fact that we observed twice as much gas in one tube than in the other, and the amount of water in the beaker decreased, we can conclude that there is twice as much hydrogen than oxygen, creating H₂O.
