What volume of air (containing 20% O 2 by volume) will be required to burn completely 10 cm 3 each of methane and acetylene? CH 4 + 2O 2 CO 2 + 2H 2 O 2C 2 H 2 + 5O 2 4CO 2 + 2H 2 O

[By Gay Lussac's law] 1 Vol. CH 4 requires 2 Vol. of O 2 10 cm 3 CH 4 will require 2 x 10 = 20 cm 3 of O 2 Given, air contains 20% O 2 by volume. Let volume of air contain 20 cm 3 of O 2 20 cm 3 O 2 is present in 100 cm 3 of air. Similarly, 2 Vol C 2 H 2 requires 5 Vol. of oxygen 10 cm 3 C 2 H 2 will require x 10 = 25 cm 3 of oxygen Given, air contains 20% O 2 by volume Let volume of air contain 25 cm 3 of O 2 25 cm 3 O 2 is present in 125 cm 3 of air. Hence, total volume of air required is 100 + 125 = 225 cm 3
