The formula weight of Lead (II) sulfide (PbS) is calculated by summing the atomic weights of its constituent elements. Lead (Pb) has an atomic weight of approximately 207.2 g/mol, and sulfur (S) has an atomic weight of about 32.1 g/mol. Therefore, the formula weight of PbS is approximately 239.3 g/mol (207.2 + 32.1).
The formula of lead (II) sulphide is PbS whilst the formula of lead (IV) sulphide is PbS2. The formula is: PbS and the number of Solubility product constants is 3x10^-25 if you're interested;)
Pb10S10 The prefix deca in decasulfide means that there are 10 sulfide ions in the formula, each with a 2- charge. So the total negative charge is 10 x 2-, which equals 20-. To balance the total sulfide charge, you need enough lead II ions to equal 20+, so that means 10 lead II ions, which equals a charge of 20+. This is not really the correct way to name this compound. It should just simply be lead II sulfide, and the proper formula would be PbS, which, if you look at the ratio of lead to sulfide ions, which is 10:10, the formula for lead II decasulfide should be reduced to PbS.
lead(II) sulfide Sulfur has an oxidation number of 2. Cross then superscript S^2 down in front of lead and there ya go.
There is copper (I) sulfide, with the formula Cu2S, and there is copper (II) sulfide with the formula CuS.
HgS, mercuric sulfide, mercury(II) sulfide
Lead(II) is Pb2+ and sulfide is S2-, so the formula is simply PbS.
Lead(II) Sulfide = PbS Lead(IV) Sulfide = PbS2
PbS
The formula of lead (II) sulphide is PbS whilst the formula of lead (IV) sulphide is PbS2. The formula is: PbS and the number of Solubility product constants is 3x10^-25 if you're interested;)
The formula for Lead Sulfide (or Lead Sulphide) is either: PbS for Lead(II) Sulphide, or PbS2 for Lead(IV) Sulphide.
The chemical formula of lead(II) nitrate is Pb(NO3)2. The chemical formula of hydrogen sulfide is H2S.
Pb (Lead) + S (Sulphur) -----> PbS (Lead Sulphide)

The formula for copper(II) sulfide is CuS the formula for copper(I) sulfide is Cu2S.
Lead (II) sulfide would contain one atom of lead per formula unit. Actually, now that I think about it, so would lead (IV) sulfide.
The formula for cobalt (II) sulfide is CoS.
The chemical formula for mercury II sulfide is HgS.
