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
Classify each of the following as a pure substance or a mixture. If a mixture, indicate whether it is homogeneous or heterogeneous: (d) sand.
