Answer:

#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.
