# Water Can Split into Hydrogen and Oxygen Under Suitable Conditions. the Equations Representing the Change Is: 2h2o(I) → 2h2 (G) + O2(G) - Chemistry

Sum

Water can split into hydrogen and oxygen under suitable conditions. The equations representing the change is:  2H2O(I) → 2H2 (g) + O2(g)
If a given experiment results in 2500cm3 of hydrogen being produced, what volume of oxygen is liberated at the same time under the same conditions of temperature and pressure?

#### Solution

Given equation is: 2H2O (I) → 2H2 (g) + O2 (g)
According to Gay-Lussac's law;
2 volume of water produces 2 volume of hydrogen and 1 volume of oxygen
i.e 2 volume of water produces = 2 volume of hydrogen
= 2500cm3
2 volume of water will produce =1 volume of Oxygen
= 2500/ 2 = 1250 cm3
i.e.= 1250 cm3
