4.  Naming is a big part of this.  You can’t finish these problems if you can’t get them started.  These are easy points you don’t want to let go. 3

5.  Synthesis Reactions pg 42  Metals and nonmetals combine to form salts. CHECK CHARGES OF IONS!!!!!  Metal Oxides and water form bases, bases have OH attached  Nonmetal oxides and water form acids  Metal oxides and nonmetal oxides form salts (you will make an oxyanion- just move one oxygen over)

6.  Magnesium burns in oxygen  Calcium reacts with chlorine gas  Potassium oxide reacts with water  Carbon dioxide is bubbled through water  Lithium oxide is added to carbon dioxide

7.  Decomposition Reactions pg 42  CHECK CHARGES OF IONS!!!!!  Carbonates decompose into oxides and CO 2  Chlorates decompose into chlorides and O 2  A binary compound may break down to produce two elements.  Hydrogen peroxide with decompose into water and oxygen gas

8.  Titanium (IV) chlorate decomposes  Copper (III) carbonate is heated  Magnesium chloride is electrolyzed  Carbonic acid is heated  Hydrogen peroxide decomposes

9.  A + BX  AX + B  You will have a chart of activity series  More active metals will replace less active metals from their compound in a solution  A less active element will have no reaction when added to a more active element!  Active metals replace hydrogen in water  Active metals replace hydrogen in acids  Active nonmetals replace less active nonmetals from their compounds in solutions

11.  Zinc is added to a solution of cobalt (II) chloride  Cadmium is added to a solution of barium iodide  Lithium is added to a solution of copper (II) chlorate  Chromium is left in water

12.  Potassium is added to sulfuric acid  Silver is added to hydrochloric acid  Chlorine gas is bubbled through a solution of sodium bromide

13.  AY + BX  AX + BY  These reactions occur in solution  Remember in solution the ions are free floating. For a reaction to occur, the ions have to come together and leave their dissolved state.  Formation of a precipitate  Formation of a gas  Formation of a molecular species

14.  Acids are soluble.  Compounds of: alkali metals, ammonium, nitrate, chlorate and acetate are soluble.  Halogens and sulfates are soluble except with silver mercury, lead, and large alkaline earth metals (calcium and up)  With the exception of the first two bullets carbonates, chromates, phosphates, sulfites, oxalates and sulfides are insoluble.  Hydroxides are insoluble with the exception of calcium, strontium and barium (lightning bolt)

15.  Hydrochloric acid reacts with silver nitrate  Potassium carbonate reacts with calcium chlorate  Sodium chloride reacts with ammonium oxalate  Scandium acetate reacts with lithium chromate

16.  Acid base neutralization reactions will produce water.  NaOH + HNO 3  H 2 O (l) + NaNO 3 (aq)  Net ionic is  H + + OH -  H 2 O

19.  Strong acids and bases are not at equilibrium, there is no reverse reaction.  Strong acids and bases will never be formed in a net ionic equation.  All other acids/bases can be formed, and will be formed by reacting the appropriate ion with a strong acid/base.  *Most other bases are insoluble

20.  Calcium hydroxide reacts with chloric acid  Hydrochloric acid reacts with calcium nitrite  Nitric acid reacts with sodium chlorite  Sodium hydroxide is mixed with zinc chloride
