### 2H2 + O2 → 2H2O2V     1V       nil2CO+ O2 → 2CO22V      1V     2VFrom equations, 2V of H2 reacts with = 1 V of O2Hence, 20 ml of H2 will react with = 10 ml of O2So, remaining O2 is 20 - 10= 10 mlSimilarly for 10 ml of CO, the oxygen required is = 5mlSo, remaining O2 is 10 - 5 = 5 ml∴ The composition of resulting mixture will be 5 ml of O2 and 10 ml of CO2.
