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?
Answer
Explanation:
Step1: Write the balanced chemical equation
$2SO_2 + O_2\rightarrow 2SO_3$
Step2: Analyze atom - conservation
In the reactants, we have 2 sulfur atoms and 6 oxygen atoms. In $SO_3$, each molecule has 1 sulfur and 3 oxygen atoms.
Step3: Determine the number of $SO_3$ molecules
Since we have 2 sulfur atoms and each $SO_3$ molecule has 1 sulfur atom, and the number of sulfur atoms is conserved in the reaction, the number of $SO_3$ molecules produced is 2.
Answer:
2
