A stick of candy is considered a pure substance because it consists of a uniform composition and distinct properties throughout. It is primarily made up of sugar and other specific ingredients that are chemically consistent, without any mixture of different substances. This uniformity means that every part of the candy has the same characteristics, distinguishing it from mixtures that contain varying components.
A stick of chalk is considered a pure substance because it consists mainly of calcium carbonate (CaCO₃) in a uniform composition throughout. In contrast, a stick of candy is not a pure substance because it typically contains a mixture of various ingredients, such as sugars, flavorings, colorings, and sometimes preservatives, resulting in a non-uniform composition. This difference in composition defines the purity of the materials.
