Question

complete the balanced molecular chemical equation for the reaction below. if no reaction occurs, write nr after the reaction arrow. be sure to include the proper phases for all species within the reaction. nh₄br(aq) + pb(no₃)₂(aq)→

Explanation:

Step1: Predict the products

A double - displacement reaction occurs. The cations and anions switch partners. The products are $PbBr_2$ and $NH_4NO_3$.

Step2: Determine the phases

According to solubility rules, $NH_4NO_3$ is soluble in water (aqueous, aq) and $PbBr_2$ is insoluble (solid, s).

Step3: Balance the equation

The balanced molecular chemical equation is $2NH_4Br(aq)+Pb(NO_3)_2(aq)
ightarrow PbBr_2(s) + 2NH_4NO_3(aq)$.

Answer:

$2NH_4Br(aq)+Pb(NO_3)_2(aq)
ightarrow PbBr_2(s) + 2NH_4NO_3(aq)$
