PLEASE AMSWER ALL QUESTIONS:) will leave good rating if everything is answers correctly and quickly!!!!!
Complete the table given that the following three reactions occur in the direction as written
a) 2Li +Fe2+ = 2Li+ + Fe
b) 2Li + Pb2+ = 2Li+ + Pb
c) Fe + Pb2+ = Fe2+ + Pb
Based on the three reactions, rank the oxidizing and reducing agents in order of strength
In the following reaction, identify the atom that is reduced and the atom that is oxidized
Bi2O3 + 2NO-3 + 2OH- = 2BiO-3 + 2NO-2 + H2O
Atom reduced__________ atom oxidized_________________
Reaction Species reduced species oxidized reducing agent oxidizing agent a) b) c)Explanation / Answer
0 +2 +1 0
2Li + Fe2+ --> 2Li+ + Fe
Fe2+ is reduced & Li is oxidized
Li reduces Fe2+ so Li is a reducing agent
Fe2+ oxidizes Li so Fe2+ is oxidizing agent
0 +2 +1 0
2Li + Pb2+ --> 2Li+ + Pb
Pb2+ is reduced & Li is oxidized
Li reduces Pb2+ so Li is a reducing agent
Pb2+ oxidizes Li so Pb2+ is oxidizing agent
0 +2 +2 0
Fe + Pb2+ --> Fe2+ + Pb
Fe2+ is reduced & Fe is oxidized
Fe reduces Pb2+ so Fe is a reducing agent
Pb2+ oxidizes Fe so Pb2+ is oxidizing agent
On comparing these threee equations ,
Li reduces Fe2+ & Pb2+ and also Fe reduces Pb2+ so the
strongest reducing agent is Li
intermediate reducing agent is Fe
weakest reducing agent is Pb
strongest oxidizing agent is Pb2+
intermediate oxidizing agent is Fe2+
weakest oxidizing agent is Li+
+3 +5 +5 +3
Bi2O3 + 2NO-3 + 2OH- ------> 2BiO-3 + 2NO-2 + H2O
Here the oxidation state of Bi increases from +3 to +5, So Bi is oxidized
The oxidation state of N decreases from +5 to +3 so N is reduced
