  1. Grade 9 and 10 Review

  2. p+ Nucleus Positive no Nucleus None e- Orbits Negative

  3. The study of matter and its properties Anything that has mass and takes up space A change that does not involve the formation of a new substance. Ex: change of state or form A change that involves the creation of a new substance. Ex: burning, any chemical reaction An observation that involves a quality of a substance (no numbers)

  4. An observation that involves a measured quantity (numbers) A sample containing more than one distinct substance A mixture that consists of one phase (ex: salt water). A mixture that contains more than one phase (ex: oil and water) A sample that contains one chemical substance (can be either an element or compound)

  5. A pure substance consisting of atoms that are all from the same element on the periodic table. A pure substance containing atoms from more than one element, bonded together chemically. Represents the number of protons in one atom of an element. Represents the mass of one atom of an element (number of protons + number of neutrons)

  6. Matter Pure Substance Solutions (Homogeneous Mixtures) Mixture Compound Heterogenous Mixtures Element

  7. Glowing Re-lights Burning Pops (explodes) Burning Goes out.

  8. 5 clues that a chemical reaction has taken place. • Heat or light given off • A new colour appears • Gas released (odour) • A precipitate forms (a solid) • The change is difficult to reverse

  9. Physical or Chemical Change? • Rusting of metal • Dissolving of sugar • Water freezing • Burning leaves • Dynamite exploding • Shattering glass Chemical Physical Physical Chemical Chemical Physical

  10. Quantitative or Qualitative? • The flame was 4 cm high • Coal is the primary source of carbon • The apple has a mass of 200g • Mercury is a silver liquid at room temperature Quantitative Qualitative Quantitative Qualitative

  11. Symbols? • Hydrogen g. Carbon • Oxygen h. Sodium • Aluminum i. Chlorine • Calcium h. Iodine • Lithium j. Gold • Potassium k. Lead H O Al Ca Li K C Na Cl I Au Pb

  12. Calcium • What group? • Atomic Mass? • Neutrons? Group 2 (alkaline earth metal) 40.08 20 (Mass of 40, subtract 20 p+)

  13. Bond Types • Ionic • Covalent Between metal and non metal Involves transfer of electrons Between 2 non metals Involves sharing of electrons

  14. Naming binary compounds • MgO • Li3P • CaBr2 • BaCl2 • K2S • AlN Magnesium oxide Lithium phosphide Calcium bromide Barium chloride Potassium sulfide Aluminum nitride

  15. Word Equations • Magnesium reacts with oxygen to produce magnesium oxide • Copper (II) sulphate reacts with lithium nitrate to produce lithium sulphate and copper (II) nitrate. magnesium + oxygen  magnesium oxide copper (II) sulphate + lithium nitrate  lithium sulphate + copper (II) nitrate

  16. Types of Reactions • Synthesis • Decomposition • Single Displacement • Double Displacement • Combustion 2 substances combine into 1 1 substance breaks into 2 or more An element displaces another in a compound. Two compounds react, trading ionic partners. Something burns in oxygen.
