Answer» a) Fe+S-FeS Here 'Fe' is oxidised from 0 to +2, while 'S' is reduced from 0 to -2. b) 2Ag,0-4Ag+0,1 'Ag' is reduced from +1 to 0, and oxygen is oxidised from -2 to 0. c)2MG +0, > 2Mgo 'Mg' is oxidised from 0 to +2 and 'O' is reduced to 0 to -2. d)Ni+H2O-Ni+H2O 'Ni' is reduced from +2 to 0 and 'H' is oxidised from 0 to +1. |
