Answer: P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)  

Explanation:

We are given two reactions which are the two steps of a mechanism:

P_4(l)+5O_2(g)\rightarrow 2P_2O_5(g)       ......(1)

P_2O_5(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)        .......(2)

To determine the net chemical equation, we will multiply equation 2

P_2O_5(g)+3H_2O(l)\rightarrow 2H_3PO_4(l)\times 2  

2P_2O_5(g)+6H_2O(l)\rightarrow 4H_3PO_4(l) .......(3)

Adding (1) and (3)

P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 4H_3PO_4(l)  

Thus, the net balanced chemical equation is:

P_4(l)+5O_2(g)+3H_2O(l)\rightarrow 4H_3PO_4(l)
