Formation of polyethylene from calcium carbide takes place as follows C a C 2 + 2 H 2 O → C a ( O H ) 2 + C 2 H 2 C 2 H 2 + H 2 → C 2 H 4 n ( C 2 H 4 ) → ( - C H 2 - C H 2 - ) n The mass of polyethylene obtained in kg from 64 kg C a C 2 is

Question

Quantrex Academy · Accepted Answer

Correct answer: 28

C a C 2 64 g + 2 H 2 O → C a ( O H ) 2 + C 2 H 2 C 2 H 2 + H 2 → C 2 H 4 28 g 64g of C a C 2 gives 28g of ethylene ∴ 64kg of C a C 2 will give 28kg of polyethylene
