1. Classifying Matter

2. Why is it possible for chemistry connects to everything around us?

3. Chemistry is the study of the composition of matter and the changes matter can undergo
But what exactly is matter???

4. Matter is…
Basically matter is anything that has mass and occupies space.
Examples: trees, water, buildings, air
In short, EVERYTHING around you is made of matter!

5. Changing Matter Physical Change Chemical Change
During a physical change, the appearance or state of the substance is changed but the composition of the substance remains the same. 
Chemical Change
During a chemical change, the original substance is changed into a different substance. 

6. Can we separate matter?
If we can physically separate the matter, it is classified as a mixture.
If we cannot physically separate the matter (can only be separated chemically), it is called a pure substance.

7. How can we separate mixtures?
Filtration
Coffee, Sand & Water
Distillation
Salt water
Chromatography
Find pick of distillation for smart board. Label parts.

8. Mixtures Mixture – physical blend of two or more components
Most samples are mixtures.
Chicken noodle soup
Italian salad dressing
Milk
Air
Can you think of any others?

9. Do all these mixtures look the same?
How does the distribution of their components look?

10. Heterogeneous Homogeneous Classifying Mixtures
Based on the distribution of their components, mixtures can be either:
Heterogeneous
Homogeneous

11. Pure Substances
Pure Substance - a material with a specific chemical composition
Examples
Gold
Silver
Salt (NaCl)
Deionized water (H2O)

12. Classifying Pure Substances
Based on their chemical composition, pure substances can be either:
Elements
Compounds

13. Properties of Matter Physical Property Chemical Property
A condition of a substance that can be observed or measured without changing the substance’s composition.
Ex: color, luster, hardness
Chemical Property
Property that describes how a substance can change into a NEW chemical
Ex: flammability, reactivity with water/air/oxygen

14. 3 Stages of Matter

15. 3 Stages of Matter Solid Liquid Gas Definite shape and volume
Cannot flow or take shape of container
Particles are compact and organized
Liquid
Constant volume
Takes shape of container its in (flows)
Particles are touching but disorganized
Gas
Takes shape of container (flows)
Expands to fill any volume
Particles are far apart and compressible
