ADDITIONAL INFORMATION
Matter is anything that occupies space and has mass. Matter is classified into two:
- Pure Substances- only one substance is present: no impurities
- Mixtures- more than one substances are present
PURE SUBSTANCES
*Elements-- cannot be divided into simpler substances
*Compounds-- made from elements chemically bonded together
MIXTURES
*Homogeneous Mixtures-- (solutions) substance completely mixed. Mixture exists in one state (or one phase)
*Heterogeneous Mixtures-- (suspensions and collides) substances separate. One state (or one phase) spread throughout the other
