Respuesta :
2NH4Br(aq) + Pb(C2H3O2)2(aq) ==> PbBr2(s) + 2NH4C2H3O2(aq)
Pb^2+(aq) + 2Br^-(aq) ==> PbBr2(s)
Answer:
2NH₄Br(aq) + Pb(C₂H₃O₂)₂(aq) → PbBr₂(s) + 2NH4C₂H₃O₂(aq)
Explanation:
Unbalanced:
NH₄Br(aq) + Pb(C₂H₃O₂)₂(aq) → PbBr₂(s) + NH₄C₂H₃O₂(aq)
There is two and one acetate ion on the reactant and product side respectively. Similarly there are one and two bromine atoms on the reactant and product side respectively.
Balanced:
2NH₄Br(aq) + Pb(C₂H₃O₂)₂(aq) → PbBr₂(s) + 2NH₄C₂H₃O₂(aq)
To balance the bromine and acetate ions on both side of the reaction we place a 2 coefficient before NH₄Br and NH₄C₂H₃O.
