Question
Balance the following equations : $P + O _2 \rightarrow \ce{P_2 O_5}$
✓
Answer
$P + O_2 \rightarrow \ce{P_2O_2}$
To balance $O$ atoms on both sides
$P +\ce{5 O_2 \rightarrow P_2O_5}$
There are $4 P$ atoms on $\ce{RHS}$
Make $P$ atoms $4$ on $\ce{LHS}$
$4 P +\ce{5O_2 \rightarrow 2 P_2O_5}$
Atoms of $P$ and $O$ are equal on both sides.
