O2 (oxygen underlined) ClO3- (chlorine underlined) Na2S2O3 (sulphur under)

AgNO3 (silver underlined) CO3 2- (Carbon underlined)

MnO2 (maganese underlined) KMnO4 (maganese underlined)

ZnSO4 (zinc underlined) MgSO3 (Sulphur underlined)
 
O2 = oxidation # is -2
CIO3-= -2 x 3= -6, but since it has a negative 1 charge the oxidation # for chlorine is +5. Because -6+5=-1
Na2S2O3= oxidation # is +4
Silver is +1
Carbon is +4
maganese is +2
manganese is +7
Zinc im unsure
Sulphur is +5
