Sagot :
Answer : The correct option is, (4) 6.0 mol
Explanation :
The given balanced ionic equation is,
[tex]3Pb^{2+}+2Cr\rightarrow 3Pb+2Cr^{3+}[/tex]
In this reaction, lead undergoes reduction and chromium undergoes oxidation.
- Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.
- Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.
Half reactions of oxidation and reduction are :
Oxidation : [tex]2Cr\rightarrow 2Cr^{3+}+6e^-[/tex]
Reduction : [tex]3Pb^{2+}+6e^-\rightarrow 3Pb[/tex]
From the reduction reaction, we conclude that 6 moles of electrons gained by the 3 moles of lead ions.
Hence, the correct option is, (4) 6.0 mole
