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: 4 molecules of sulfur dioxide (so₂) react with 2 molecules of oxygen (o₂) to produce some amount of sulfur trioxide (so₃). complete the table below. chemical element number of atoms in the reaction o s during 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\rightarrow2SO_3). Given (4SO_2+2O_2), the ratio is consistent with the balanced - equation ratio.
Step2: Calculate the number of oxygen atoms
In (4SO_2), the number of oxygen atoms is (4\times2 = 8). In (2O_2), the number of oxygen atoms is (2\times2=4). So the total number of oxygen atoms is (8 + 4=12).
Step3: Calculate the number of sulfur atoms
In (4SO_2), the number of sulfur atoms is (4\times1 = 4).
Step4: Determine the number of (SO_3) molecules
From the balanced equation (2SO_2 + O_2\rightarrow2SO_3), when (4SO_2) and (2O_2) react, the number of (SO_3) molecules produced is (4) (since the ratio of (SO_2) to (SO_3) is (1:1) in the given amounts).
Answer:
| Chemical element | Number of atoms in the reaction |
|---|---|
| O | 12 |
| S | 4 |
| 4 |
