Question

Complete and balance the molecular equation for the reaction of aqueous ammonium bromide, NH4BrNH4Br , and aqueous lead(II) acetate, Pb(C2H3O2)2Pb(C2H3O2)2 . Include physical states.

Answer 1

Answer: The molecular equation is given below.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This means that total mass on the reactant side is equal to the total mass on the product side.

This also means that the total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side.

The balanced chemical equation for the reaction of ammonium bromide and lead (II) acetate follows:

$2NH_4Br(aq.)+(CH_3COO)_2Pb(aq.)\rightarrow 2CH_3COONH_4(aq.)+PbBr_2(s)$

This is a type of double displacement reaction because here, exchange of ions takes place.

Hence, the molecular equation is given below.
