20ml h2 10ml co and 20ml o2 are exploded in an eudiometer. what will be the vol. and composition of the mixture after cooling it to room temp.

Expert Answer:

2H+ O2 → 2H2O

2V     1V       nil

2CO+ O2 → 2CO2

2V      1V     2V

From equations, 2V of H2 reacts with = 1 V of O2

Hence, 20 ml of H2 will react with = 10 ml of O2

So, remaining O2 is 20 - 10= 10 ml

Similarly for 10 ml of CO, the oxygen required is = 5ml

So, remaining O2 is 10 - 5 = 5 ml

∴ The composition of resulting mixture will be 5 ml of Oand 10 ml of CO2.
