1. How to predict a Product

2. Synthesis Acid anhydride + water  acid Base anhydride + water  base Nonmetallic oxide is acid anhydride Metallic oxide is base anhydride

3. Decomposition Electrolysis: splits the molecule Heating: most common

4. Heat hydroxides Produce the oxide and water Exceptions: group 1 hydroxides

5. Heat carbonates Produce oxide and CO 2 Exceptions: group 1 carbonates

6. Heat sulfates Produce oxide and sulfur trioxide Exceptions: groups 1 and 2

7. Heat nitrates Produce oxide, oxygen, and nitrogen dioxide Exceptions: group I nitrates produce nitrites and oxygen

8. Heat chlorates All produce the chloride and oxygen gas

9. Heat oxides Only for silver, mercury, platinum, palladium, and gold Produce metal and oxygen gas

10. Single replacement Free metal must be higher on the reactivity series Free nonmetal must be higher on the nonmetal reactivity series

11. Double replacement Both conditions must occur – Both reactants must be soluble in water – Must be evidence of a chemical reaction Color change Precipitate Bubbles

12. Complete combustion Always produces carbon dioxide and water

13. Decomposition problems what if you heat: Calcium oxide Aluminum hydroxide Sodium chlorate Sodium sulfate Sodium nitrate Calcium nitrate Magnesium carbonate Magnesium sulfate

14. answers Calcium oxide: nothing Aluminum hydroxide aluminum oxide and water Sodium chlorate sodium chloride and oxygen Sodium sulfate nothing Sodium nitrate sodium nitrite and oxygen Calcium nitrate calcium oxide, O 2, NO 2 Magnesium carbonate MgO and CO 2 Magnesium sulfate nothing
