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 cmNO

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

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.
