Answer

Explanation:

Step1: Identify reaction type

This is a synthesis reaction as two substances combine to form one product.

Step2: Write chemical formulas

Diphosphorus pentoxide is $P_2O_5$, water is $H_2O$, and phosphoric acid is $H_3PO_4$. So the equation becomes $P_2O_5 + H_2O \to H_3PO_4$.

Step3: Balance the equation

We need 2 moles of $H_3PO_4$ to balance the P - atoms. Then we need 3 moles of $H_2O$ to balance the H - and O - atoms. The balanced equation is $P_2O_5+3H_2O = 2H_3PO_4$.

For sub - question 2, since no reactions are given, we can't answer it.

Answer:

a. Synthesis reaction b. $P_2O_5 + H_2O \to H_3PO_4$ c. $P_2O_5+3H_2O = 2H_3PO_4$
