1 Unit 5 (bonding & naming) Review You need to use a sheet a paper with this clicker!

2 1) An unknown black/purple substance is placed in water and the water turns purple after mixing but there are also black chunks at the bottom of the beaker. When the solution is tested with a light bulb (conductivity) apparatus, the light bulb does not light up. What type(s) of bond(s) are present in the substance and explain how you know this. 2) Explain why are substances that contain metallic bonds such good conductors of electricity. 3) Explain why ionic substances cannot conduct electricity when not dissolved in water.

3 What type of bond and what type of electron interaction occurred in the compound CaCl 2 ? 1.Ionic – Transferred 2.Covalent – Transferred 3.Covalent – Shared 4.Ionic - Shared

4 If an unknown chemical compound is placed in water and the solution turns color (the light bulb doesn’t light) but after mixing, there is some material on the bottom, what can be said about this compound? 1.Polar Covalent 2.Mix of polar and nonpolar Covalent 3.Mix of ionic and nonpolar 4.Nonpolar covalent

5 What type of compounds do not conduct any electricity and are not soluble in water? 1.Nonpolar Covalent 2.Polar Covalent 3.Ionic 4.Metallic

8 What is the chemical name of H 3 P0 5 ? 1. phosphoric acid 2. phosphorous acid 3. hydrophosphoric acid 4. hypophosphorous acid 5. perphosporic acid

9 What is the chemical name of Fe 2 (SO 2 ) 3 ? 1.iron hyposulfite 2.iron (II) hyposulfite 3.iron (III) hyposulfite 4.diiron trihyposulfite 5.not listed

10 What is the chemical name of Cd(NO 4 ) 2 ? 1.cadmium (I) pernitrate 2.cadmium (II) pernitrate 3.cadmium (III) pernitrate 4.cadmium (IV) pernitrate 5.not listed

11 What is the chemical name of Pb(CrO 4 ) 2 ? 1.lead (I) chromate 2.lead (II) chromate 3.lead (III) chromate 4.lead (IV) chromate 5.not listed

12 What is the chemical name of HClO? 1. chloric acid 2. chlorous acid 3. hydrochloric acid 4. hypochlorous acid 5. perchloric acid

13 What is the chemical name of H 2 CO 3 ? 1. carbonic acid 2. carbonous acid 3. hydrocarbonic acid 4. hypocarbonous acid 5. percarbonic acid

14 What is the chemical name of Al(OH) 3 ? 1. aluminum hydroxide 2. aluminum oxygen hydrogen 3 3. aluminum (III) hydroxide 4. aluminum trihydroxide 5. aluminum hydride

15 If a chemical compound has high conductivity in solution (lights a 60 watt light bulb), high melting point, and is water soluble what type of bond is occurring? 1.Ionic 2.Polar Covalent 3.Nonpolar Covalent 4.Metallic

16 What type of compound has low conductivity in solution (meter readings between 1 – 16; doesn’t light up a light bulb apparatus) and is soluble in H 2 O? 1.Nonpolar Covalent 2.Polar Covalent 3.Ionic 4.Metallic
