Question

from the following reaction sequence:
CaC2+H2O-----> CaO+C2H2
C2H2+H2 --->C2H4
nC2H4 ---->(C2H4)n polythene
calculate the mass of polythene which can be produced from 10 kg of CaC2.​

Answer 1

Answer:

4.375 kg.

Explanation:

From the given equation we get that the weight of the calcium carbide is 64 gram and the gram molar mass of the polythene will be 28 gram. Again from the equation we get 1 mol of the CaC2 reacts to form 1 mol of the acetylene.

So, for 64 gram of the CaC2 gives 24 gram of polythene so 1 gram will give 28/64.

So, from the question we have to calculate 10 kg or 10000 gram of the CaC2 we will get 28/64*10000=4375 gram or 4.375 kg of polythene.
