Question

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 1

Answer:

Step-by-step explanation:

Answer 2

The ratios of oxygen atom and sulfur atom is an illustration of equivalent ratios.

There are 12 oxygen atoms, when the number of sulfur atom is 6.

From the diagram, we have:

$S = 1$

$O_x = 2$

So, the ratio is:

$S : O_x = 1 : 2$

When there are 6 sulfur atoms, the equation becomes

$6 : O_x = 1 : 2$

Express as a fraction

$\frac{O_x}{6}= \frac{2}{1}$

Multiply both sides by 6

$O_x = 2 \times 6$

$O_x =12$

Hence, there are 12 oxygen atoms
