Question

Va rog mult am nevoie urgent!!! Vreau sa stiu daca e bun raspunsul

Answer 1

n CH4 reactionat = 0,45×8 = 3,6 moli

n CH4 nereactionat = 8-3,6 = 4,4 moli

x.............x................x...........x
CH4 + Cl2 => CH3Cl + HCl
y............2y.................y.................2y
CH4 + 2Cl2 => CH2Cl2 + 2HCl

x/y = 2/1 => x = 2y = 2,4 moli CH3Cl

x+y = 3,6 <=> 3y = 3,6 => y = 1,2 moli CH2Cl2

nHCl format = x+2y = 4,8 moli

n Cl2 reactionat = x+2y = 2,4+2,4 = 4,8 moli

n Cl2 nereactionat = 5-4,8 = 0,2 moli

n amestec gazos final = 0,2+3,6+4,4+4,8= 13 moli

%CH3Cl = 2,4/13×100 = 18,46
