Question

sulfur dioxide is a gas released when volcanoes erupt. it can react with oxygen gas to form sulfur trioxide, a chemical that can harm living things. consider the following reaction: 2 molecules of sulfur dioxide (so₂) react with 1 molecule of oxygen (o₂) to produce some amount of sulfur trioxide (so₃). use the number of atoms in the reaction to answer the question below. chemical element number of atoms in the reaction o 6 s 2 during this reaction, how many molecules of sulfur trioxide (so₃) are produced?

Explanation:

Step1: Analyze sulfur atoms

Each $SO_3$ molecule has 1 sulfur atom. There are 2 sulfur atoms in the reactants.

Step2: Determine number of $SO_3$ molecules

Since the number of sulfur atoms is conserved in the reaction, and there are 2 sulfur atoms available for forming $SO_3$, the number of $SO_3$ molecules formed is 2.

Answer:

2
