question 3 of 19
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.
pb(no₃)₂(aq) + licl(aq)→

Explanation:

Step1: Predict products

When lead - nitrate ($\text{Pb(NO}_3)_2$) and lithium - chloride ($\text{LiCl}$) react, a double - displacement reaction occurs. The cations and anions switch partners. The possible products are lead - chloride ($\text{PbCl}_2$) and lithium - nitrate ($\text{LiNO}_3$). The reaction is $\text{Pb(NO}_3)_2(aq)+2\text{LiCl}(aq)
ightarrow\text{PbCl}_2(s) + 2\text{LiNO}_3(aq)$.

Step2: Check solubility rules

Lead - chloride ($\text{PbCl}_2$) is insoluble in water and forms a solid precipitate (s), while lithium nitrate ($\text{LiNO}_3$) is soluble in water (aq) according to solubility rules (nitrates are always soluble and most chlorides are soluble except for those of silver, lead, and mercury(I)).

Answer:

$\text{Pb(NO}_3)_2(aq)+2\text{LiCl}(aq)
ightarrow\text{PbCl}_2(s)+2\text{LiNO}_3(aq)$
