Question

Ni + PbO2+ 4H+ Pb2+ + Ni2++ 21,0 In the above redox reaction, use oxidation numbers to identify the element oxidized the element reduced the oxidizing agent and the reducing agent. name of the element oxidized: Nickel name of the element reduced: formula of the oxidizing agent: Ni formula of the reducing agent:

Answer 1

Answer:-

Name of the element oxidized : Nickel (Ni)

Name of the element reduced : Lead (Pb)

​​​​​formula of the oxidizing agent : PbO₂

formula of the reducing agent : Ni

Ni —> Ni 2+ + 2e- - Coxidation) PbO, the P6 27 (Reduction) ty
