Chapter Overview

Chemistry is the study of matter and so it is important to be able to understand the properties of matter and to classify matter based on type. All samples of matter have both physical and chemical properties, and thus can undergo physical and chemical changes. Classifications of matter include elements, compounds, and mixtures. Careful observation of changes in matter must be made in order to determine if each change is physical or chemical in nature.
