When solutions of KCl and Pb(NO3) 2 are mixed, a precipitate forms. Which of the following is the balanced equation for the double replacement reaction that occurs?

A) KCl(aq) + Pb(NO3)2(aq) → KNO3(aq) + PbCl2(S)

B) KCl(aq) + Pb(NO3)2(aq) → KNO3(aq) + PbCl(s)

C) 2KCI (aq) + Pb(NO3)2(aq) + 2 KNO3(aq) + PbCl2 (s)

D) KNO3(aq) + PbCl2(s) → KCl(aq) + Pb(NO3)2(aq)

E) K+ (aq) + NO3(aq) → KNO3(aq)

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
