Answer

Explanation:

Step1: Write the balanced chemical equation

The reaction is (2SO_2 + O_2\rightarrow 2SO_3).

Step2: Analyze atom - conservation

In (2SO_2), there are 2 sulfur atoms and 4 oxygen atoms. In (O_2), there are 2 oxygen atoms. So in total, there are 2 sulfur atoms and 6 oxygen atoms on the reactant - side. In (SO_3), each molecule has 1 sulfur atom and 3 oxygen atoms. Since there are 2 sulfur atoms and 6 oxygen atoms in the reactants, and each (SO_3) molecule has 1 sulfur and 3 oxygen atoms, the number of (SO_3) molecules produced is 2 to balance the atoms.
