**Notes:**

**A heterogeneous balance**is composed of an ext than one phase. Usual examples encompass reactions involving solids and also gases, or solids and also liquids.

**Substances that have the right to be had in formula K space substances through a gas phase (g) or aqueous phase (aq)**. Pure solids and also liquids room unincluded in the equilibrium consistent expression because they execute not influence the reactant amount in ~ equilibrium in the reaction, so they are disregarded and kept at 1.
