Answer:
The correct answer -
a. Cd and Pb(NO3)2
b. Redox reactions
c. Pb and Cd(NO3)2
Step-by-step explanation:
This is the reaction known as the redox or reduction-oxidation reaction of metals. In this particular reaction, there are two reactants Cadmium (III) in solid-state and lead (II) nitrate in the aqueous state. At the end of this reaction, the products that we get are lead (II) in solid-state and Cadmium (III) nitrate in the aqueous state.
cadmium (s)+ lead nitrate (aq) = lead (s) + cadmium nitrate (aq)
Cd (s) + Pb2+(aq) → Pb(s) + Cd2+(aq)
Here, Oxidizing agent is Pb2+ and the reducing agent is Cd.
