A Piece of Lead Metal Was Added to an Aqueous $\rarr$

A piece of lead metal was added to an aqueous solution of copper(II) nitrate, and within a few minutes it was observed that the lead turned black and crumbled. The characteristic blue solution of copper (II) ions had faded. (NOTE: Lead forms a 2+ ion when it reacts.) Select the balanced chemical equation for this reaction.

A) Pb(s) + CuNO₃(aq) $\rarr$ Cu(s) + Pb(NO₃) ₂(aq)
B) 2Pb(s) + Cu(NO₃) ₂(aq) $\rarr$ Cu(s) + 2Pb(NO₃) ₂(aq)
C) Pb(s) + Cu(NO₃) ₂(aq) $\rarr$ 2 Cu(s) + Pb(NO₃) ₂(aq)
D) Pb(s) + Cu(NO₃) ₂(aq) $\rarr$ Cu(s) + Pb(NO₃) ₂(aq)
E) None of the above
