The reaction 4N2O + CH4 → CO2 + 2H2O + 4N2 takes place in the gaseous state. If the volumes of all the gases are measured at the same temperature, and pressure, calculate the volume of dinitrogen oxide (N2O), required to give 150cm3 of steam.

उत्तर
According to Gay-Lussac's law : In the equation
4N2O + CH4 → CO2 + 2H2O + 4N2
Vol. of H2O produced is = 2 vol. = 150cm3
Vol. of N2O required is = 4 vol. = 150 x 4 / 2 = 300 cm3
300cm3 of dinitrogen oxide (N2O) is required to give 150 cm3 of steam.

Calcium carbide is used for the artificial ripening of fruits. Actually the fruit ripens because of the heat evolved while calcium carbide reacts with the moisture. During this reaction calcium hydroxide and acetylene gas are formed. If 200 cm3 of acetylene is formed from a certain mass of calcium carbide, find the volume of oxygen required and carbon dioxide formed during the complete combustion. The combustion reaction can be represented as below.
