Question

Va rog sa ma ajutati daca stiti☺

Answer 1

Raport de 1:2:2:1 => x moli A, 2x moli B, 2x moli C si x moli D
A-CH3Cl, B-CHCl2, C-CHCl3, D-CCl4
1mol............................1mol
CH4 + Cl2 -> CH3Cl + HCl
x..................................x moli
1mol................................2moli
CH4 + 2Cl2 -> CH2Cl2 + 2HCl
2x....................................4x moli
1mol..............................3moli
CH4 + 3Cl2 -> CHCl3 + 3HCl
2x..................................6x moli
1mol............................4moli
CH4 + 4Cl2 -> CCl4 + 4HCl
x..................................4x moli
15x=0,03 => x=0,002moli
nCH4=6x=0,012moli
n=V/Vm => V=n*Vm
VCH4=0,012*22,4=0,2688l CH4=268,8ml CH4
