Answer:
The molarity of the Pb(NO3)2 solution is 0.24 M
Explanation:
Assuming there was no loss during filtration, we can calculated amount of moles Pb(NO3)2 from the 13.25 g of PbCl2 ussing molar mass of PbCl2
13.25 g / 278.1 g = 0.04 moles of PbCl2
According balanced equation 2NaCl + Pb(NO3)2 = 2NaNO3 + PbCl2, 1 mol of Pb(NO3)2 produces 1 mol of PbCl2. So, 0.04 moles of Pb(NO3)2 produces PbCl2
Molarity is = moles of solute/volumen of solution (L)=0.04/0.2= 0.24
I hope my answer helps you
A metal and non metal favor the formation of ionic compounds from element. ionic compounds are formed when between metal and non metal because metal has ability to loss electrons and net positive charge ion to form cation while non metal has ability to gain electrons .form anion and net negative charge ion.

Homogeneous mixture is the answer for this
Hydrogen gas is H2, so it is not an atom, it is a molecule.
