उत्तर

\[\ce{2C2H2 + 5H2O -> 4CO2 + 2H2O(l)}\]

2 vol. of C2H2 need O2 = 5 vol.

From equation, 2V of C2Hrequires = 5 V of O2

So, for 400ml C2H, O2 required = `400 × 5/2`

=1000 ml

Similarly, 2 V of C2H2 gives = 4 V of CO2

So, 400ml of C2H2 gives CO2 = `400 × 4/2`

∴ Volume of carbon dioxide formed = 800ml

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.
