If the volume of water produced during the reaction doubled, what would happen to the ratio of hydrogen to oxygen in the following equation: 2 H2+ O2 --> 2 H2O
What did the volume of water double FROM? Is the water gaseous? Is it at the same T and P as the reactants?
There must be more information that goes with this question.
The ratio of H to O (2 to 1) must stay the same if the only product is H2O, regardless of the amount of H2O produced.
