This document provides an overview of chemistry concepts including: - Chemistry is the study of matter, its properties, and how it interacts and changes. - Alchemy tried to transform metals like lead into gold but was speculative. - Antoine Lavoisier was the "Father of Modern Chemistry" and established oxygen's role in combustion. - Matter occupies space, has mass, and can be sensed. It exists as solids, liquids, gases, or plasma.

2. What is CHEMISTRY?
Branch of science that deals with the
identification of the substances of which matter
is composed; the investigation of their
properties and the ways in which they interact,
combine, and change’ and the use of those
processes to form substances.

3. What is CHEMISTRY?
Branch of science that deals with the study of
the composition, properties, and interaction of
matter.

4. ALCHEMY
Form of speculative thought that tried to
transform base metals such as lead and copper
into silver or gold.

5. ANTOINE-LAURENT de
LAVOISIER
- Father of Modern
Chemistry
- A French nobleman who
was central to the 18th
century chemical
revolution.
- Determined oxygen was
a key substance in
combustion , and gave
the element its name.

7. Matter
Anything that
- Occupies space
- Has mass
- Can be felt by one or more senses
Types:
-solid
-liquid
-gas
-plasma

9. Mixture
Made when two or more substances are
combined, but they are not combined chemically.
2 types:
Homogeneous
Heterogeneous

11. Homogeneous Mixture
(solution)
A solid, liquid or gaseous mixture that has the same
proportions of its components throughout a given sample.
Shows a single form when substances combined.
Eg.
solid- plasticware
liquid- Coffee, saltwater, blood
gas- air

13. Heterogenous Mixture
A mixture in which the composition is not uniform throughout
the mixture.
Classification:
Colloids
Suspensions

14. Colloids
A mixture with one substance consisting of microscopically
dispersed particles is suspended throughout another
substance.
Eg. Whipped cream, mayonnaise, milk, gelatin,
paper

15. Suspension
A mixture with finely distributed solid in liquid. The solid is not
dissolved in liquid.
Eg. Cereal bowl, fog, smog, mixture of chalk and
water, sand in water

17. Determine if a mixture is a solution, colloid or suspension.
1.Jelly 6. soda 11. smog
2. Cereal bowl 7.whipped cream 12.mayonnaise
3.Fog 8. sand in water 13.milk
4.Paper 9. coffee 14.air
5.Saltwater 10.blood 15. sand in water

18. Pure Substance
A form of matter having constant chemical
composition and characteristic properties.
Classification:
-Element
-Compound

19. Element
A pure substance consisting of only atoms of the same kind.
Smaer numbers of protons in their nuclei.
-oxygen
-magnesium
-calcium

20. Compound
A pure substance consisting of 2 or more different types of
atom.
-water
-salt

21. Determine if a pure substance is an
element or compound.
1.oxygen 6. baking soda
2. Gold 7. sugar
3.water 8. calcium
4.Ozone 9. carbon dioxide
5. zinc 10. fluoride
