Work Step by Step

This question deals with determining which figures contain a mixture of an element and a pure compound. An element is a substance that can not be broken down any further by chemical means. It contains only one type of atom. A compound is a substance made up of two or more elements, so it contains two or more types of atoms. This means the figures that contain a mixture of an element and a pure compound will contain some molecules that have only one type of atom, as well as some molecules that have more than one type of atom. The figures that fit this description are figures ii and iii. Figures ii and iii contain a mixture of an element and a compound.
