Question

The ratio of Hydrogen to Oxygen in water is _____.

Answer 1

1. The reaction of water formation is,
   $2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
2. Atoms of Hydrogen and Oxygen are found in conjunction to form water molecules.
3. Water molecules adhere to the rule of constant proportions because their mass ratio is unchanging.
4. Two molecules of water are created when two molecules of the diatomic hydrogen gas and one molecule of the diatomic oxygen gas unite.
5. The ratios of Hydrogen to oxygen are 2:1, Hydrogen to water are 1:1, and Oxygen to water is 1:2.
