Enter the oxidized element first CI2(aq) + 2 Nal(aq) rightarrow I2(aq) + 2NaCI(aq) Express your answer as chemical symbols separated by a comma. Enter the oxidized element first Pbs(8) + 4H2O2(aq) rightarrow PbSO4(8) + 4H20 (l) Express your answer as chemical symbols separated by a comma. Enter the oxidized element first
oxidisation means increase in oxidation no and reduction decrease....
A-H,N
B-Al,Fe
C-I,Cl
D-S,O
