WEBThe law of constant composition can be used to distinguish between compounds and mixtures of elements: Compounds have a constant composition; mixtures do not. Water is always 88.8% O and 11.2% H by weight regardless of its source. Brass is an example of a mixture of two elements: copper and zinc.

19 Classification of Matter (Elements, Compounds, Mixtures)
WEBKey Points. Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

WEBA compound contains atoms of different elements, chemically joined together. Compounds form in chemical reactions, and you need other chemical reactions to separate a compound into its elements.
WEBExplain the difference between an element and a compound. Explain the difference between a homogeneous mixture and a heterogeneous mixture. One useful way of organizing our understanding of matter is to think of a hierarchy that extends down from the most general and complex to the simplest and most fundamental ( Figure 3.3.1 3.3. 1 ).
