Question

Give the formula, elements and their ratio in Sulphur dioxide

Answer 1

The molecular formula for Sulphur dioxide is $\mathbf{\left(}{\mathbf{SO}}_{\mathbf{2}}\mathbf{\right)}$.

Identify the elements and their ratio in sulphur dioxide:

1. Thus, the elements in Sulphur dioxide are sulphur $\mathbf{\left(}\mathbf{S}\mathbf{\right)}$ and oxygen $\mathbf{\left(}\mathbf{O}\mathbf{\right)}$.
2. The molecular formula shows that there is $1$ atom of sulphur $\mathbf{\left(}\mathbf{S}\mathbf{\right)}$ and $2$ two atoms of oxygen $\mathbf{\left(}\mathbf{O}\mathbf{\right)}$.
3. Thus, the ratio of sulphur $\mathbf{\left(}\mathbf{S}\mathbf{\right)}$ and oxygen $\mathbf{\left(}\mathbf{O}\mathbf{\right)}$ is $\mathbf{1}\mathbf{:}\mathbf{2}$.
