From the following reaction sequence, ...

From the following reaction sequence,
`{:(CaC_(2) + H_(2) O to CaO+ C_(2)H_(2)),(" "C_(2)H_(2)toC_(2)H_(4)),(" "nC_(2)H_(4) to (C_(2)H_(4))_(n)):}`
calculate the mass of polyethylene which can be produced from 10 kg of `CaC_(2)`

Text Solution

Verified by Experts

Wt. of `(C_(2)H_(4))_(n) = (1000 g CaC_(2)) xx ((1 "mole Ca"C_(2))/(64 "g Ca"C_(2))) `
` ((1 "mole "C_(2)H_(2))/(1"mole Ca" C_(2))) xx ((" 1 mole " C_(2) H_(4))/( " 1 mole "(C_(2)H_(2))))`
`(("1 mole " (C_(2)H_(4))_(n))/( "n more " C_(2) H_(4))) xx (( " 28 n g " (C_(2) H_(4))_(n))/("1 mole " (C_(2) H_(4))_(n)))`
= 4375 g
(note that n cancels)
Second Method Apply POAC for C atoms.
