Question

Balance the following chemical equation:-

@1-FeCl3 + SO2 +H2O-------->FeCl2 + H2SO4 HCl

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

Please explain me the full process how can I balance them easily... I'm unable

Answer 1

1.  2FeCl3 + 2 H2O + SO2 = 2FeCl2 + 2HCl + H2SO4 .

2. K2Cr2O7 + 14 HCl = 2 KCl + 2 CrCl3 + 2 Cl3 + 7 H2O
