2. H2SO4 + HBr ---> SO2 + Br2 + H2O
3. N2O + H2. ---> H2O + NH3
4. HClO4 + ClO2 + H2O ----> HClO3
5. P4 + H2O + HNO3 ---> H3PO4 + NO
Homework Answers
The reactions are balanced in oxidation number counting method, in acidic medium.
In the oxidation number change method the underlying principle is that the gain in the oxidation number in one reactant must be equal to the loss in the oxidation number of the other reactant.
