Answer (1 of 4): White phosphorus is a highly reactive element, which is spontaneously oxidized in the presence of air. The phosphorus oxides transform into acids when they are in direct contact with humid mucous membranes (Leisewitz et al., 2000). so we'll need 5 lots of O2 to get 10 on the right hand side and the left hand side, and P4 is already on both sides so that's fine. Phosphorus pentachloride is used as a chlorinating agent in many organic syntheses, such as production of alkyl and acid chlorides.
