What chemical reaction does this equation represent?
2KCl + Pb(NO3)2 --> 2KNO3 + PbCl2

A: Two molecules of potassium nitrate and one molecule of lead chloride react to form one molecule of lead nitrate and two molecules of potassium chloride.

B: One molecule of potassium nitrate and one molecule of lead chloride react to form one molecule of lead nitrate and one molecule of potassium chloride.

C: Two molecules of potassium chloride react with two molecules of lead nitrate to form one molecule of potassium nitrate and two molecules of lead chloride.

D: Two molecules of potassium chloride react with one molecule of lead nitrate to form two molecules of potassium nitrate and one molecule of lead chloride.

Answer 1

For Anyone that put A, its wrong, the correct answer is D

Answer 2

the eqn is 2KCl + Pb(NO3)2 --> 2KNO3 + PbCl2

first chemical is KCl: K is potassium, Cl is chloride.

so that leaves choice C and D

only 1 molecule of Pb(NO3)2 so correct ans is D
