Phosphorus triiodide is formed from its elements. Oxides and Oxyacids Phosphorus trioxide, P 4 O 6, and phosphorus pentoxide, P 4 O 10 are acid anhydrides of phosphorus oxyacids and thus readily react with water. Any substance that contains only one kind of an atom is known as an element.Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P 4) or sulfur (S 8) cannot be broken down into simpler substances by these reactions.. P 4 O 6 (s) + 6 H 2 O(l) → 4 H 3 PO 3 (aq) It reacts vigorously with hot water, via a complex set of reactions, to form red phosphorus, phosphines, H 3 PO 3 and H 3 PO 4. 125:347.
