Sagot :

Answer:

Explanation:

Here, we want to get the type of reaction this chemical equation gives

As we can see, phosporus is burnt in oxygen to give phosphorus (v) oxide

Since it is burning, it is expected that heat is given off to the surroundings. A type of chemical reaction in which we have heat given off is an exothermic reaction

Since heat is a form of energy, we can state that the reaction is exothermic because energy is given off
