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. KNO3 (aq) + PbCl2 (s) ¨ KCl(aq) + Pb(NO3)2 (aq)

c. K+ (aq) + NO3-(aq) ¨ KNO3 (aq)

d. 2KCl (aq) + Pb(NO3)2 (aq) ¨ 2 KNO3 (aq) + PbCl2 (s)

e. KCl(aq) + Pb(NO3)2 (aq) ¨ KNO3 (aq) + PbCl(s)

And you think what? Just count the atoms up on both sides and find the ONLY equation which has the same number of atoms on each side.

It's that simple? Thank you. I made it harder than it was.

By the way, The answer is D. :0)
