1. Good Morning! 11/27/2015 Starter: Did you go through the review? Today we are going to… –Go over the review. –Then take the test

2. On the test you will be given The Periodic Table Polyatomic Ions table Covalent Prefixes Metals with Multiple charges

3. Chemical Bonding and Reactions Review

4. Element # of Valence electrons NameCharge Carbon (C)4Carbon Doesn’t like to ionize Oxygen (O)6Oxide-2 Iodine (I)7Iodide Potassium (K) 1Potassium+1 Calcium (Ca)2Calcium+2

5. Section 2: Writing ionic compounds. Practice Calcium Oxide = CaO Both 2 Copper (I) Iodide = CuI Both 1 Lithium Bromide = LiBr Both 1 Magnesium Phosphide = Mg 3 P 2 Mg is +2, P is -3

6. Section 3: Naming ionic compounds: CrCl 3 = Chromium (III) Chloride –Chromium (II) Chloride is CrCl 2 CuBr = Copper (I) Bromide –Copper (II) Bromide is CuBr 2 FeO = Iron (II) Oxide –Iron (III) Oxide is Fe 2 O 3 MgS = Magnesium Sulfide

7. Section 4 & 5: Writing formulas and naming them. K and PO 4 = K 3 PO 4 Potassium Phosphate Mg and SO 4 = MgSO 4 Magnesium Sulfate NH 4 and SO 4 = (NH 4 ) 2 SO 4 Ammonium Sulfate Na and OH = NaOH Sodium Hydroxide

8. Section 6: Naming covalent compounds. Remember the prefixes and write the following examples: N 2 O N 2 O 5 CBr 4 CS 2 =Dinitrogen Monoxide =Dinitrogen Pentaoxide =Carbon Tetrabromide =Carbon DiSulfide

9. Section 7: Naming covalent compounds. Remember the prefixes and write the following examples: Tetracarbon Octobromide Trinitrogen hexasulfide Pentaphosphorus heptaoxide Sulfur Diodide =C 4 Br 8 =N3S6=N3S6 =P5O7=P5O7 =SI 2

10. Section 8: Balancing Reactions Zn + HCl  ZnCl 2 + H 2 CH 4 + O 2  CO 2 + H 2 O H 2 O 2  H 2 O + O 2 CaSO 4 + NaC 2 H 3 O 2  Ca(C 2 H 3 O 2 ) 2 + Na 2 SO 4 2 22 2 2 2

11. Section 9: Classifying the Reactions Zn + 2 HCl  ZnCl 2 + H 2 Single Replacement (Sr) CH 4 + 2 O 2  CO 2 + 2 H 2 O Combustion (Cb) 2 H 2 O 2  2 H 2 O + O 2 Decomposition (D) CaSO 4 +2NaC 2 H 3 O 2  Ca(C 2 H 3 O 2 ) 2 +Na 2 SO 4 Double Replacment (Dr)
