Question

HCl + K2Cr2O7 -------- Cl2 + CrCl3 + KCl + H2O​

Answer 1

Respuesta:

24KClO3 + 72H2SO4 → 24O2 + 48KHSO4 + 4Cl2 + 72H2O

K2Cr2O7 + HCl → CrCl3 + KCl + Cl2 + H2O

K2Cr2O7 + 14HCl → 2KCl + 2CrCl3 + 3Cl2 + 7H2O

A B. C D. E. F

K--------------------- 2A = D ✓

Cr-------------------- 2A = C. ✓

O---------------------- 7A = F H---------------------- B = 2B Cl---------------------- B = 3C + D + 2E

A=2. D=4. C=4 7A =. F B = 3C + D + 2E
