Lead metal is produced by heating solid lead(II) sulfide with solid lead(II) sulfate, resulting in liquid lead and sulfur dioxide gas. Write a balanced equation for the reaction using complete formulas for the compounds with phase labels. (Type your answer using the format 2H2SO4(l) for 2 H2SO4(l). Use the lowest possible coefficients.)

solid lead(II)sulfide = PbS (s)
solid lead(II)sulfate = PbSO4 (s)
liquid lead = Pb (l)
sulfur dioxide gas = SO2 (g)
Skeletal equation:
PbS + PbSO4 ~~> Pb + SO2
Balancing the equation simply requires you to make sure that the number and type of each atom does not change as you go from reactants to products.
As it stands unbalanced, you see:
2 Pb reactants, 1 Pb products
2 S reactants, 1 S products
4 O reactants, 2 O products
Balancing this equation took me 5 seconds; I trust you can use the above information to figure it out in a little over that time.
