Answer:

Pb(NO3)2 + 2NaCl = PbCl2 + 2NaNO3

Step-by-step explanation:

Lead nitrate is Pb(NO3)2

Sodium Chloride is NaCl

The basic reaction is:

Pb(NO3)2 + NaCl = PbCl2 + NaNO3

Now we need to balance the equation. Note that the lead nitrate contributes 2 (NO3) units, but there is only 1 NO3 on the product side. So start by adding a second NaNO3:

Pb(NO3)2 + NaCl = PbCl2 + 2NaNO3

Now we have 2 Na atoms on the right side, so add a "2" to the NaCl:

Pb(NO3)2 + 2NaCl = PbCl2 + 2NaNO3

This is starting to look good. Lets check the atom/unit counts on both sides of the equation:

Reactants Products

Pb 1 1

NO3 2 2

Na 2 2

Cl 2 2

The equation is now balanced. Pb(NO3)2 + 2NaCl = PbCl2 + 2NaNO3
