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.\nconsider the following reaction:\n2 molecules of sulfur dioxide (so₂) react with 1 molecule of oxygen (o₂) to produce some amount of sulfur trioxide (so₃).\nuse the number of atoms in the reaction to answer the question below.\n| chemical element | number of atoms in the reaction |\n| ---- | ---- |\n| o | 6 |\n| s | 2 |\nduring this reaction, how many molecules of sulfur trioxide (so₃) are produced?
Answer
Explanation:
Step1: Write the balanced chemical equation
The reaction is (2SO_{2}+O_{2}\rightarrow 2SO_{3}).
Step2: Analyze atom - conservation
In the reactants, we have 2 sulfur atoms and 6 oxygen atoms. In (SO_{3}), each molecule has 1 sulfur atom and 3 oxygen atoms.
Step3: Calculate the number of (SO_{3}) molecules
Since we have 2 sulfur atoms and each (SO_{3}) molecule has 1 sulfur atom, and also considering oxygen - atom conservation (6 oxygen atoms in reactants and 3 oxygen atoms per (SO_{3}) molecule), the number of (SO_{3}) molecules is 2.
Answer:
2
