Use the half-equations written earlier and combine them to form the overall equation for.
1. CI2 to CI
with
Br to Br2
2. Pb2+ to Pb
with
Al to A13+
3. H2SO4 to HS
with
I- to I2
4. HNO3 to NO
with
Fe to Fe2+
5. H2SO4 to SO2
with
Br- to Br2

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
