Question

help
imi ies 0.52l VCl2...

Answer 1

CH4 + Cl2 => CH3Cl + HCl

CH4 + 2Cl2 => CH2Cl2 +2HCl

CH4 + 3Cl2 => CHCl3 + 3HCl

CH4 => CH4 (nereactionat)

x - CH4 moli
y - CH2Cl2 moli
z - CHCl3 moli
n CH4 = 8/22,4 = 0,357 moli

x/y = 4/3 => y = 3x/4
x/z = 4/1 => z = x/4

x+y+z = 0,357 <=> x+3x/4+x/4 = 0,357 <=> 2x = 0,357 => x = 0,178 moli

y = 0,134 moli compus dihalogenat

V Cl2 = 2×n compus = 2×0,134 = 0,267 moli × 22,4 = 6 L
