Formation of polyethylene from calcium c...

Formation of polyethylene from calcium carbide takes place as follows
`CaC_(2)+2 H_(2)O rarr Ca(OH)_(2)+C_(2)H_(2)`
`C_(2)H_(2)+H_(2) rarr C_(2)H_(2)`
`N(C_(2)H_(4)) rarr (-CH_(2)-CH_(2)-)_(n)`
The amount of polyethylene obtained from `64.1 kg CaC_(2) ` is

A

7 kg

B

14 kg

C

21 kg

D

28 kg

Text Solution

Verified by Experts

The correct Answer is:
D
`underset"64 g"(CaC_2)+2H_2O to Ca(OH)_2+C_2H_2`
`C_2H_2+H_2 to underset"28 g"(C_2H_4)`
64g of `CaC_2` gives 28 g of ethylene
`therefore` 64 kg of `CaC_2` will give 28 kg of polyethylene
