2SO_2 + O_2 ->2 SO_3
Synthesis

Explanation:

Write the unbalanced equation:

SO_2 + O_2 -> SO_3

The left side of the equation has one more oxygen atom than the right side, so half the coefficient of O_2

SO_2 + 1/2 O_2 -> SO_3

Double all coefficients:

2SO_2 + O_2 ->2 SO_3

This equation is now balanced because there are two S atoms and six O atoms on each side.

Because the reaction has the form of A+B->AB, this is a synthesis reaction.
