What is formed when Iodine is absorbed by hypo solution?

Write the balanced chemical equations for the following reactions:
$(1)$ Reaction between $MnO_4^-$ and $I^-$ in neutral or faintly alkaline solution.
$(2)$ Reaction between $MnO_4^-$ and $C_2O_4^{2-}$ in acidic medium $(H^+)$.

Assign $A, B, C, D$ from given type of reaction.
$CuSO_4(aq.) + Zn(s) \longrightarrow ZnSO_4(aq.) + Cu(s)$

The reaction of aqueous $KMnO_4$ with $H_2O_2$ in acidic conditions gives

The oxidation state of chromium in the final product formed by the reaction between $KI$ and acidified potassium dichromate solution is

What is the equivalent weight of $IO_4^-$ when it is converted to $I_2$ in an acidic medium?
