Question

What is the mole ratio of Hydrogen and Oxygen?

Answer 1

1. Mole ratio is defined as a ratio that is obtained by the separation of compounds.
2. The separation of compounds is called decomposition reaction.
3. The decomposition of water occurs through the electrolysis.
4. Therefore, at equilibrium the process of decomposition stops and we obtain Hydrogen and Oxygen in the gaseous form.
5. The decomposition reaction is represented as:
   $2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to 2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$
6. Thus, we concluded that the decomposition reaction or separation of water molecules produces 2 atoms of Oxygen and 4 atoms of Hydrogen.
7. The mole ratio is 4 moles of Hydrogen or 2 moles of dihydrogen and 1 mole of Oxygen.
