List of top Chemistry Questions on Balancing a redox reaction asked in COMEDK UGET

In the redox reaction, taking place in acidic medium: $\text{X MnO}_4^-(aq) + \text{Y SO}_2(g) \rightarrow \text{Mn}^{+2}(aq) + \text{HSO}_4^-(aq)$,} the ratio of X:Y in a stoichiometrically balanced equation will be:

x moles of $\text{K}_2\text{Cr}_2\text{O}_7$ oxidises 1 mole of ferrous oxalate, in acidic medium. Hence 'x' is:

Identify the correct coefficients (a), (b), (c) and (d) in the following equations
\[ \text{i) } xMnO_4^- + (a)\,SO_3^{2-} + (b)\,H^+ \rightarrow xMn^{2+} + (a)\,SO_4^{2-} + (c)\,H_2O \]
\[ \text{ii) } (c)\,S_2O_3^{2-} + (d)\,MnO_4^- + H_2O \rightarrow (d)\,MnO_2 + (b)\,SO_4^{2-} + xOH^- \]
