Question

Zn + HNO3 -> Zn(NO3)2 + NH4NO3 + H20

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

Answer 1

4Zn + 10HNO₃ → 4Zn(NO₃)₂ + NH₄NO₃ + 3H₂O

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

Answer 2

Cân bằng

a) 4 : 10 : 4 : 1 : 3

b) 1 : 14 : 2 : 2 : 3 : 7

Answer 3

4Zn + 10HNO3 → 4Zn(NO3)2 + NH4NO3 + 3H2O

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