Question

Complete and balance the molecular equation for the reaction of aqueous ammonium bromide, NH4Br , and aqueous lead(II) acetate, Pb(C2H3O2)2 . Include physical states. molecular equation: NH_{4}Br(aq) + Pb(C_{2}H_{3}O_{2})_{2}(aq) -> NH4Br(aq)+Pb(C2H3O2)2(aq)⟶

Answer 1

Aqueous ammonium bromide and lead(II) acetate do not react to form a precipitate, thus no net chemical reaction occurs and the substances remain dissolved.

Pb(NO3)2(aq) + 2NaCl(aq) → 2NaNO3(aq) + PbCl2(s).

Step-by-step explanation:

When aqueous solutions of ammonium bromide, NH4Br, and lead(II) acetate, Pb(C2H3O2)2, are mixed together, a double displacement reaction can occur. However, since both reactants are soluble and do not form an insoluble product or a precipitate in this specific combination, no net reaction will take place. The final molecular equation suggests that there are no changes on both sides of the equation. Therefore, the correct representation would be NH4Br(aq) + Pb(C2H3O2)2(aq) → No Reaction.

However, it is important to note that in a double displacement reaction that does proceed, such as when lead(II) nitrate reacts with sodium chloride to produce soluble sodium nitrate and a precipitate of lead(II) chloride, the balanced molecular equation would be Pb(NO3)2(aq) + 2NaCl(aq) → 2NaNO3(aq) + PbCl2(s).

Answer 2

Answer : The complete balanced molecular equation will be,

`2NH_4Br(aq)+Pb(C_2H_3O_2)_2(aq)\rightarrow 2NH_4C_2H_3O_2(aq)+PbBr_2(s)`

Explanation :

Balanced chemical equation : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The complete balanced molecular equation will be,

`2NH_4Br(aq)+Pb(C_2H_3O_2)_2(aq)\rightarrow 2NH_4C_2H_3O_2(aq)+PbBr_2(s)`
