Question

How would you express Tin (IV) oxide as a chemical formula?

Answer 1

`SnO_2`

Explanation:

We know oxides are compounds made of a metal, and oxygen.

Oxygen always has a `-2` charge in these compounds, and since this compound has a metal with `+4` charge, it takes two oxygens to balance the charge of one metal atom.

The symbol for tin is `Sn` (after its latin name, Stannum), so we just put them together:

`SnO_2`
