Classifying Matter
All matter is either a pure substance or a mixture
made of one type
of particle
made of more than one
type of particle
There are two kinds of pure substances:
1. ELEMENTS - found on the periodic table
- cannot be broken down into simpler forms
C
EX
2. COMPOUNDS - when two or more elements combine
O
C
O
There are four kinds of mixtures
1. MECHANICAL MIXTURE
- see all parts of the mixture
- heterogeneous- doesn't look the same throughout
- separated by hand, sieve
2. SOLUTION
- homogeneous- appears the same throughout
- one substance dissolved in another
- aqueous solutions are when substances are
dissolved in water
- separated by distillation
3. SUSPENSION
- homogenous
- tiny particles are suspended in another substance
- separated by filter
4. COLLOID
- homogeneous
- cloudy mixture, particles are so tiny, can't be
filtered ourt
