Explanation / Answer

1) The balanced equation is

2 Cr2O7-2 + 16H+ + 3CH3OH ---------> 4Cr+3 + 3HCOOH + 11 H2O

The oxidising agent is Cr2O7-2 and reducing agent is CH3OH

2) the balanced equation is

NO2- + 2Al + 2H2O --------------> NH4+ + 2 AlO2-

NO2- is the oxidising agent and Al is the reducing agent

3)

4BrO3- + 5N2H4 -------------> 2 Br2 + 5N2 + 8H2O + 4OH-

the oxidisng agent is BrO3- and reducing aent is N2H4
