2. stem the diagram shows the structure of a molecule of sulfur dioxide. the ratio of oxygen atoms to sulfur atoms in sulfur dioxide is always the same. how many oxygen atoms (o) are there when there are 6 sulfur atoms (s)? explain how you got your answer.
Answer
Explanation:
Step1: Identify the ratio
The chemical formula of sulfur dioxide is $SO_2$, so the ratio of oxygen atoms to sulfur atoms is 2:1.
Step2: Set up proportion
Let $x$ be the number of oxygen atoms. We have the proportion $\frac{x}{6}=\frac{2}{1}$.
Step3: Solve the proportion
Cross - multiply: $x = 6\times2$. $x=12$.
Answer:
12
