A) 7 kg
B) 14 kg
C) 21 kg
D) 28 kg
Correct Answer: D
Solution :
\[\underset{\text{64}\,g}{\mathop{Ca{{C}_{2}}}}\,+2{{H}_{2}}O\to Ca{{(OH)}_{2}}+{{C}_{2}}{{H}_{2}}\] \[{{C}_{2}}{{H}_{2}}+{{H}_{2}}\to \underset{\text{28}\,g}{\mathop{{{C}_{2}}{{H}_{4}}}}\,\] 64g of \[Ca{{C}_{2}}\] gives 28g of ethylene \[\therefore \] 64kg of \[Ca{{C}_{2}}\] will give 28kg of polyethyleneYou need to login to perform this action.
