Balance the following equations by the oxidaiton number method . (i)

1.	Balance the following equations by the oxidaiton number method . (i) Fe^(2+)+H^(+)+Cr_(2)O_7^(2-)rarrCr^(3+)+Fe^(3+)+H_2O (ii) I_2+NO_3^(-) rarr NO_2+IO_3^(-) (iii) I_2+S_(2)O_(3)^(2-)rarr I^(-) +S_(4)O_(6)^(2-) (iv) MnO_(2)+C_(2)O_(4)^(2-)rarrMn^(2+)+CO_2
Answer» SOLUTION :Try yourself Balanced equation are (i) `6Fe^(2+)+Cr_2O_(7)^(2-)+14H^(+) rarr 2Cr^(3+)+6Fe^(3+)+7H_2O` (II) `I_2+10NO_3^(-)+8H^(+)rarr 10NO_2+2IO_(3)^(-)+4H_2O` (iii) `I_2+2S_2O_3^(2-)rarr2I^(-)+S_4O_(6)^(2-)` (IV) `MnO_2+C_2O_4^(2-) +4H^(+)rarrMn^(2+)+2CO_2+2H_2O`
