1. Chemistry Project By: Ashley Lauren Garcia Of Class 7O8!!!:{D Enjoy!!!

2. Matter!!! Matter is everywhere in the world… In your hair In the air In food In liquid… Etc.

3. O3 states of matter 1)Solid- when the particles are really mushed together. EX: ice, containers, ice cream, cheese, chocolate. 2) Liquid-when the particles have more room to move. Ex: seawater, paint, water, gatorade, kool-aid. 3)Gas- when the particles have A LOT of room to bounce off each other and they go crazy\wild. Ex: air, carbon dioxide, hydrogen peroxide, oxygen, smoke.

4. Physical\chemical properties Physical: can be observed without changing the identity of the substance(properties). The original properties of matter such as color, density, hardness, are examples of the physical property. Chemical: can not be observed with changing the identity of the substances. You can tell it’s a chemical change and not a physical change because in a chemical change you can see rusting on a bike when it gets old. Etc.

5. The difference of physical\chemical The difference between a physical and chemical property is…a substance that doesn’t change. Ex: boiling water, dissolving sugar, dicing potatoes, “whipping” egg whites. And a chemical property is…. Substances that do change. Ex: Iron Rusting, Eggs Cooking, Bread Rising(baking), milk souring(Rotting), and Suntanning.

6. Atoms An Atom is… What everything is made up of.(singular, molicule is multiples) Ex: Grass, Flowers, computer, notebook, pictures, jewlery, Etc. Parts of an Atom: Protons(+), Nutrons(none), Electrons(-). Protons have positive charge, Electrons have a negative charge, nutrons have no charge.

7. Elements an Element is…a substance that cannot be decomposed into simpler substances. Elements can be spotted from other substances experimentally.(different) Ex: Oxygen, gold, carbon dioxide, Helium, Hydrogen.

8. Compounds A compound is… a pure substance and its NOT A MIXTURE. Ex: table salt is not a compound because it’s a mixture of calcium and sodium chloride and calcium silicate. A compound is made up of two or more elements (NOT the same element) elements combined with fixed ratios, is the way compounds are formed. Ex: Abietane, Acetylene, Acetal, Acetamide, Acid Fuchsin.

9. Periodic table A periodic table is a HUGE chart that shows all the elements and their Atomic #, Atomic Mass(weight), symbol, and name. To find the amount of Prontons you just look at atomic #,the same with the Nutrons. But the Electrons is different because you have to subtract the atomic# from the atomic mass(weight). The trends\patterns are that they are different colors based on what type they are. For Example: Metals, non-metals, metalloid.

10. Substances + Mixtures Mixture- can be separated by a simple physical process. Is what u get when you combine two substances in a way that no chemical reaction occurs. substances-it’s a homogeneous mixture. It has many different properties throughout all the samples. Mixture examples: sand and water, salt and water, sugar and salt. Substance examples: tin, sulfur, diamond, water, pure sugar, table salt, baking soda(sodium bicarbonate)

11. Heterogeneous+Homogen eous Homogeneous is when something is evenly mixed. Ex: Lemon-Aid, Iced Tea, Kool-Aid, sugar dissolved, salt dissolved. Heterogeneous is when something is UN-evenly mixed. Heterogeneous Example: salad, orange juice (with pulp), air, mud, sand water, oil, nitrogen, soup.

12. Solutions A solution is a homogeneous mixture, of two or more substances that are evenly mixed. Solute- substance that is dissolved( Ex: Sugar) Solvent- substances that dissolves the solute (Ex: Water) Solutes and solvents can be gases, solids, or liquids combined in many different ways.

13. Solubility Solubility-(Noun) SOLUBILITY means it can easily be dissolved by liquid, it can dissolve particular substances, the property( difficulty or problem) that makes it possible to solve them.

14. THE END!!!! Well thank you for looking at my power point I worked hard on it and I hope you Enjoyed it as much as I Enjoyed making it!! It took me a long time to do this because I had to research everything ALL OVER again… but I got through it and that is all that matters.
