If a nail made of elemental iron [Fe(s)] is placed in an aqueous solution of a soluble palladium(II) salt [Pd2+(aq)], the nail will gradually disappear as the iron enters the solution as Fe3+(aq) and palladium metal [Pd(s)] forms.

Is this a redox equation?

Balance and show the net ionic equation that describes this reaction.

Yes, its a redox reaction.

Explanation:

It is obviously a redox reaction.

Oxidation: Fe (s)=Fe3+(aq)+3e-(aq)

Reduction: Pd2+(aq)+2e-=Pd(s)

Fe os oxidized as its oxidation state increased from 0 to +3

Pd is reduced as ots oxidation state decreased from +2 to 0.

Add 2x oxidation + 3x Reduction and cancel electrons to get ionic equation:

2Fe (s) + 3Pd2 + (aq) = 2Fe3+(aq)+3Pd (s)

b. is the answer hoped i        

yes
