Phosphorus occurs naturally in the form of fluorapatite, CaF2 * 3Ca3(PO4)2, the dot (asterisk) indicating 1 part CaF2 to 3 parts Ca3(PO4)2. This mineral is reacted with an aqueous solution of sulfuric acid in the preparation of a fertilizer. The products are phosphoric acid, hydrogen fluoride, and gypsum, CaSO4 * 2H2O. Write and balance the chemical equation describing this process.
