प्रश्न
450 cm3 of nitrogen monoxide and 200 cm3 of oxygen are mixed together and ignited. Caclulate the composition of resulting mixture.
\[\ce{2NO + O2 → 2NO2}\]
उत्तर
\[\ce{2NO + O2 → 2NO2}\]
2 V 1 V 2 V
From equation, 1V of O2 reacts with = 2 V of NO
200cm3 oxygen will react with = 200 × 2 = 400 cm3 NO
2 vols. of NO produces = 2 vols. of NO2
∴ 400 cm3 of NO produces NO2 = 400 cm3
∴ Vol. of NO left unused = 450 − 400
= 50 cm3

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.
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.
