Elements
1. Defintion
a) substance made out of one type of atom
- 2 or more of them can make a compound, chemically mixed
2. Examples
a) hydrogen
b) Oxygen
Compound
1. Defintion
a) A substance that is made out of 2 or more elements chemically combined
2. A new substance is produced with different properties from elements that made it.
a)Harder to separate than mixtures
- Another chemical reaction needs to happen
3. Examples
a)Water
b) Salt
Mixtures
1. Definition:
a)Combinations of substance held together by physical force
2. Remains own structures
a)easy to separate
3. Heterogenous
a)Unevenly distributed
b)Mixtures
- Separating Mixtures
i) Physicals
ii)filtration
! Using filter paper to separate the salt, sand and water mixture
$ Separated water: Filtrate
4. Homogenous
a) Evenly distributed
b)Solutions
- Examples
i) brine
- Separating Solutions
i)Distillation
! Separating salt and water
ii)Evaporation
! Using bunsen burner to separate the brine
iii)Chromatography
! Separating colour mixtures using the ascending method
! Ascending Method
! Wick Method
- Solubility
i)Solutes
! Substance that is dissolved
! Example: salt and sugar
ii) Solvents
!Substance that dissolves
!Example: white spirit, water, petrol, acetone and alchahol.
iii)Affects
! Temperature
!Own structure
! Pressure
! Concentration
$ Experiment: Using Temperature, Copper Sulphrate and Water
iv) Soluble and insoluble
! can be dissolved = soluble
! cannot be dissolved = insoluble
5. Examples
a) Salad Dressing
b) solid solid mixture: Alloy
- Made out of carbon and iron
Salt
1. Found in
a)sea
b)limestone caves
- Stalactites
i)hangs on cave roof
- Stalagmites
i) Grows at cave ground due to the water drippings of stalactites
- Calcium Carbonate
i)chemical that turn objects into lime stone
! petrification
$ process of turning things into stone
$ Used to preserve objects

Many of our solution experiments used the brine soltion!!!
