  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+Homogeneous • 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.
