Balance the following equations by ion electron (half reaction ) metho

1.	Balance the following equations by ion electron (half reaction ) method : {:((i) ,H_2S+MnO_4^(-)+H^(+),rarr,S+Mn^(2+)+H_2O),((ii) ,Cr_2O_7^(2-)+H^(+)+Fe^(2+),rarr,Cr^(3+)+Fe^(3+)+H_2O),((iii),""AsO_3^(3-)+IO_3^(-),rarr,AsO_4^(3-)+I^(-)),((iv),""SnO_2+C,rarr,Sn+CO):}
Answer» Answer :(i) `5H_2S+2MnO_4^(-) +16H^(+) rarr 5S+2Mn^(2+)+8H_2O` (II) `6FE^(2+)+Cr_2O_7^(2-) +14H^(+)rarr 6Fe^(3+)+2Cr^(3+) +7H_2O` (iii) `""3AsO_3^(3-)+IO_3^(-) rarr 3AsO_4^(3-) +I^(-)` (iv) `""SnO_2+2CrarrSn+2CO`
