Complete and balance the following chemical equations: (a) \[ 2MnO_4^-(aq) + 10I^-(aq) + 16H^+(aq) \rightarrow \] (b) \[ Cr_2O_7^{2-}(aq) + 6Fe^{2+}(aq) + 14H^+(aq) \rightarrow \]
In an acidic solution, permanganate ions (\( \text{MnO}_4^- \)) act as an oxidizing agent and oxidize iodide ions (\( I^- \)) to iodine (\( I_2 \)). The balanced equation for this reaction is as follows:
\[ 2 \, \text{MnO}_4^-(aq) + 10 \, \text{I}^-(aq) + 16 \, \text{H}^+(aq) \rightarrow 2 \, \text{Mn}^{2+}(aq) + 5 \, \text{I}_2(aq) + 8 \, \text{H}_2\text{O}(l) \]
In this reaction, permanganate ions are reduced to \( \text{Mn}^{2+} \), and iodide ions are oxidized to iodine.
In an acidic solution, dichromate ions (\( \text{Cr}_2\text{O}_7^{2-} \)) are reduced to chromium(III) ions (\( \text{Cr}^{3+} \)), while iron(II) ions (\( \text{Fe}^{2+} \)) are oxidized to iron(III) ions (\( \text{Fe}^{3+} \)). The balanced equation for this reaction is:
\[ \text{Cr}_2\text{O}_7^{2-}(aq) + 6 \, \text{Fe}^{2+}(aq) + 14 \, \text{H}^+(aq) \rightarrow 2 \, \text{Cr}^{3+}(aq) + 6 \, \text{Fe}^{3+}(aq) + 7 \, \text{H}_2\text{O}(l) \]
In this reaction, the dichromate ions are reduced to \( \text{Cr}^{3+} \), and iron(II) is oxidized to iron(III).

Rupal, Shanu and Trisha were partners in a firm sharing profits and losses in the ratio of 4:3:1. Their Balance Sheet as at 31st March, 2024 was as follows:
(i) Trisha's share of profit was entirely taken by Shanu.
(ii) Fixed assets were found to be undervalued by Rs 2,40,000.
(iii) Stock was revalued at Rs 2,00,000.
(iv) Goodwill of the firm was valued at Rs 8,00,000 on Trisha's retirement.
(v) The total capital of the new firm was fixed at Rs 16,00,000 which was adjusted according to the new profit sharing ratio of the partners. For this necessary cash was paid off or brought in by the partners as the case may be.
