2) The following series of reactions were carried out. PbCO (s) + 2HNO:(aq) → Pb(NO3)2(aq) + H₂O(1) + CO2(g) Pb(NO3)2(aq) + 2HBr(aq) → 2HNO3(aq) + PbBrz(s) (a) If a student starts with 2.457 g of lead(II) carbonate for the first reaction and all other reagents are added in excess, what is the theoretical yield of lead(11) bromide solid? (b) If the student isolates 2.998 g of lead(11) bromide, what is the percent yield?
