ightarrow p _ { 2 } o _ { 5 } )
2) ( agno _ { 3 } + cacl _ { 2 }
ightarrow agcl + ca ( no _ { 3 } ) _ { 2 } )
3) ( na + o _ { 2 }
ightarrow na _ { 2 } o )
4) ( h _ { 3 } po _ { 4 } + koh
ightarrow k _ { 3 } po _ { 4 } + h _ { 2 } o )
5) ( al _ { 2 } o _ { 3 } + al + o _ { 2 } )
6) ( fe + cl _ { 2 }
ightarrow fecl _ { 3 } )
multiple-choice question

# Explanation:
## Step1: Count atoms on both sides
On the left - hand side (LHS), we have $P$ and $O_2$. On the right - hand side (RHS), we have $P_4O_{10}$.
For $P$ atoms: In $P_4O_{10}$, the number of $P$ atoms is $4$. So we need $4$ $P$ atoms on the LHS.
For $O$ atoms: In $P_4O_{10}$, the number of $O$ atoms is $10$. Since $O_2$ is on the LHS, and if we let the coefficient of $O_2$ be $x$, then $2x = 10$, so $x = 5$.

## Step2: Write the balanced equation
The balanced equation is $4P+5O_2
ightarrow P_4O_{10}$

# Answer:
$4P + 5O_2
ightarrow P_4O_{10}$ (the first option among the multiple - choice)
