1. decomposition of Potassium hydroxide. 2KOH ---> K 2 O + H 2 O nickel + aluminum carbonate ---> Ni + Al 2 (CO 3 ) 3 ----> NR C 5 H 12 O 2 + O 2 ---> C 5 H 12 O 2 + 8O 2 ---> 5CO 2 + 6H 2 O A + B ----> AB Synthesis/Combination AB ---> A + B Decomposition

2. decomposition of zinc carbonate ZnCO 3 ---> ZnO + CO 2 balanced synthesis of magnesium oxide 2Mg + O 2 ----> 2MgO synthesis of barium chlorate BaCl 2 + 3O 2 ---> Ba(ClO 3 ) 2 hydrogen bromide + iron ---> 2HBr + Fe ----> FeBr 2 + H 2 copper (II) hydroxide + phosphoric acid ---> 3Cu(OH) 2(aq) + 2H 3 PO 4(aq) ---> Cu 3 (PO 4 ) 2(aq) + 6H 2 O (l) precipitate? not solid, but liquid water is formed

3. A + BC ----> AC + B Single Replacement - Check Activity Series AB + CD ---> AD + CB Double Replacement - Use Solubility Table What reaction ALWAYS has the products H 2 O and CO 2 ? Combustion What is the net ionic equation for the reaction between silver nitrate and aluminum chloride? 3AgNO 3(aq) + AlCl 3(aq) --->3AgCl (s) + Al(NO 3 ) 3(aq) 3Ag + (aq) + Cl - (aq) ---> 3AgCl (s) what are the spectator ions? Al +3 (aq) and NO 3 - (aq)

4. CuSO 4 + KCN -> CuCN + K 2 SO 4 + C 2 N 2 2 KO 2 + CO 2 -> K 2 CO 3 + O 2 4 2 2 3 P 4 O 6 -> P 4 + P 2 O 4 4 1 6 Al + KOH + H 2 O -> KAlO 2 + H 2 2 2 2 2 3 C 12 H 26 + O 2 ----> CO 2 + H 2 O 2 37 24 26
