For each of the following unbalanced half-reactions, determine
whether an oxidation or reduction is occurring:
1) Mn2+ ⟶ MnO2
2) NO3 − ⟶ NO
the answer for 1 is
and for b is
so I want to know for b how the oxidation state on Mn was
+4?
and for d how you the oxidation state on N was +5 and then
+2?
please I need the answeras soon as possible
