Question

A certain amount of ethyne reacts completely with 𝛨2, in the presence of catalyst 𝑁𝑖. The saturated compound A produced is completely combusted with air (20% v / v 𝑂2), producing 17.6 g 𝐶𝑂2. Calculate:

a) The mass of ethyne and the mass of 𝛨2 that reacted.

b) The volume of air required for the complete combustion of A, measured in STP conditions.

Answer 1

a) Mass of Ethyne=6.45g, Mass of H2=3.77g

b)Volume of air required=67mL
