Pure substances are classified into elements and compounds, while mixtures can be homogeneous or heterogeneous. Compounds have a fixed chemical composition, unlike mixtures, which can vary and be separated by physical methods.
Insights
- Elements and compounds are distinct categories of pure substances, with compounds composed of different atoms in fixed ratios, while mixtures involve variable compositions through physical mixing.
- The classification of substances as elements, compounds, or mixtures provides a framework for understanding their properties and behavior, highlighting the importance of composition and structure in defining their characteristics.
