We’re being asked to identify if sand is a pure substance or a mixture. If it’s a mixture, identify if it’s homogeneous or heterogenous.


Recall that mixtures are combinations of two or more pure substances (elements or compounds)

Mixtures are not chemically combined.


Mixtures can either be:

• Homogenous: the components are evenly distributed and indistinguishable from each other

• Heterogenous: the components are not evenly distributed and distinguishable from each other
