  1. Chemistry Project By: Diana Salinas 71o

  2. What is matter? A) An object that take up space and has mass B) The color of the object C) The mixtures Answer A

  3. States of Matter Solid Liquid 1. Has definite shape 1. Atoms move alittle 2. Has definite volume more freely 3. Atoms are packed tightly 2. Water 4.Particles vibrate 3. Atoms move 5. It is hard differently depending on khjj temperature.

  4. States of Matter Liquid 4. Takes the shape of a container 5. definite volume Gas 1.Takes up whole volume 2. Particles get excited and move farther and farther 3. Definite shape 4. cannot see a gas 5.carbon dioxide

  5. Physical and Chemical Properties Physical Properties- Is without changing the makeup of a substance you can also observe or measure it. Examples: color, smell, freezing point, boiling point, and melting point. Chemical Properties-Is when the properties of an object have a reaction. Examples: Hydrogen balloon, burning steel wool, alka seltzer, Zinc, Iodine reactions. What is the difference between them? The difference between them is that physical you check the shape, temperature,weight, etc.... With chemical you cannot observe checking the 5 senses .

  6. Physical and Chemical Properties What is the difference between them? The difference between them is that physical you check the shape, temperature,weight, etc.... With chemical you cannot observe checking the 5 senses

  7. Physical and Chemical Changes Physical Change- Is a change that does not produce (make) a new substance. Example: stirring an egg, painting wood, cutting bread, water, glass breaking. Chemical Change- Are changes that result in the productions of another substance. Example: burning paper, digesting food, baking a cake, fireworks, good car rusting. What is the difference between them? Physical Change does not make a new substance, but Chemical Change does .

  8. Atom What is an Atom? It is the smallest part of matter. An Atom has 3 different parts -Protron- positive charge -Electron- negative charge -Neutron- neutrally charged

  9. Atom model electrons (-) proton(+) nucleus neutron (O)

  10. Element What is an Element? is a pure substance that cannot be broken down into any simpler substances by chemical methods. Example: 1 2 carbon - element Dubnium - element 6 - atomic # 105 - atomic # C - symbol Db - symbol 12.o11 - atomic mass 262 - atomic mass

  11. Element Example: 3 4 Oxygen - element Nitrogen - element 8 - atomic # 7 - atomic # O - symbol N - symbol 15.999 - atomic mass 14.007 - atomic mass Example: 5 Aluminum - element 13 - atomic # Al - symbol 26.982 - atomic mass

  12. Compound What is a Compound? A thing that is composed of 2 or more separated elements. Examples:Salt Barite Copper Tin Wood Steel Aluminum Hematite Plastic Cotton

  13. Periodic Table What is a Periodic Table? -The periodic table is a table of the chemical elements in which the elements are arranged by order of atomic number in such a way that the periodic properties of the elements are made clear. How are they used? They are used to quickly locate information of that certain element. What is the pattern? The arrangement of all elements are in order to increase atomic #.

  14. Substance and Mixtures Substance- A material with a definite chemical composition. Mixtures- A material with a definite physical composition. What is the difference between them? The difference between them is that with substance they cannot be broken down physically, also a mixture cannot be broken do chemically.

  15. Heterogeneous and Homogeneous What is the difference between them? Heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together. Heterogeneous Ex: Homogeneous Ex: - sand - blood - salt - glass of juice - tea - mixture of alcohol and water - soda - hard wine - milk - alcohol

  16. Solutions What is a Solution? A solution is a homogeneous mixture of one or more solutes dissolved in a solvent. examples: - salt in water - tea - sugar in coffee - sugar in water - coffee Solute- The substance that dissolves in a solvent to produce a homogeneous mixture Solvent- The substance in which a solute dissolves to produce a homogeneous mixture

  17. Examples Solute examples- Solvent examples- -chromium - salt -iodine -water -eggshells -glue -nail polish

  18. Solubility What does Solubility mean? The quantity of a particular substance that can dissolve in a particular solvent.
