(g) for gas, (s) for solid, (l) for liquid
Explanation:
In a chemical equation, the three states of matter are expressed as (g) for gas, (s) for solid, and (l) as liquid. They should be written as a subscript after the chemical formula, but that has become less common.
Example:
Two moles of liquid mercury react with oxygen gas to produce two moles of solid mercury (II) oxide.
