Answer
Explanation:
Step1: Balance sulfur atoms
There is 1 sulfur atom on both sides initially, so sulfur is already balanced.
Step2: Balance oxygen atoms
On the left - hand side, there are 2 oxygen atoms in $SO_2$ and 2 in $O_2$, a total of $2 + 2=4$ oxygen atoms initially. On the right - hand side, there are 3 oxygen atoms in $SO_3$. To balance the oxygen atoms, we use the least - common multiple method. The balanced equation is $2SO_2(g)+O_2(g)\rightarrow2SO_3(g)$.
