Sodium phosphate.
It is phosphorus pentaoxide P2O5 which exists in dimeric form P4O10.

Burning of anything is a chemical change. Combustion (burning) is a chemical reaction; it is simply where oxygen is added to, for example, an element, and turns it into an oxide. Burning phosphorus would result in phosphorus oxide. P + O2 --> P4010
White phosphorus, it is a chemical that catches fire on contact with oxygen.

White phosphorus is a very reactive chemical because of its structure. When it is heated some, it can react with oxygen to create phosphorus pentoxide (it is in this exothermic reaction that you see the glow). So it is indeed a chemical change.
Aluminium*, with chemical symbol Al; phosphorus, with chemical symbol P; and oxygen, with chemical symbol O.
The empirical formula for phosphoric acid is H3PO4. Its molecular formula is P2O5·3H2O. It is composed of the elements hydrogen, phosphorus and oxygen. Most solutions of phosphoric acid are composed of some amount of H3PO4 in water, H2O.For more information about phosphoric acid, see the Web Links to the left.
