Question:
A student mixes 25.1 g of sodium bicarbonate with 2.560 g of zinc chloride in a beaker. Determine the mass of the mixture.
Homogeneous and Heterogeneous Mixtures:
In chemistry we frequently encounter two or more different substances that are combined together in some container. The substances may be mixed in any combination of starting solid, liquid or gaseous phases. The resulting mixture will either be homogeneous or heterogeneous. A homogeneous mixture will have a uniform composition of the contributing substances, such that its composition is independent of the mixture mass. A common example is any solution prepared from some pair of solute and solvent species.
