Anglesite. Anglesite is a lead sulfate mineral with the chemical formula PbSO 4. It occurs as an oxidation product of primary lead sulfide ore, galena. Anglesite occurs as prismatic orthorhombic crystals and earthy masses, and is isomorphous with barite and celestine. It contains 74% of lead by mass and therefore has a high specific gravity of 6.3.Chemical Formula: (Zn,Fe)S : Composition: Molecular Weight = 96.98 gm Zinc 64.06 % Zn Iron 2.88 % Fe Sulfur 33.06 % S _____ 100.00 % : Empirical Formula: Zn 0.95 Fe 2+ 0.05 S ...

The active ingredient in a product is the ingredient that causes the intended effect.The charges of cations and anions dictate their ratios in ionic compounds, so specifying the names of the ions provides sufficient information to determine chemical formulas. However, because covalent bonding allows for significant variation in the combination ratios of the atoms in a molecule, the names for molecular compounds must explicitly identify …In this case we need to remove three electrons to get to eight electrons, meaning that Cu 3+, Ag 3+, and Au 3+ are d 8 ions. Cu and Ag are not very stable in the oxidation state +3, therefore examples of square planer Cu (III) and Ag (III) are fairly rare.
