4) Double displacement: This is when the anions and cations of two different molecules switch places, forming two entirely different compounds. These reactions are in the general form: One example of a double displacement reaction is the reaction of lead (II) nitrate with potassium iodide to form lead (II) iodide and potassium nitrate: Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3 A and C come first because they are the positive metals If two ionic compounds combine, it’s probably a double displacement reaction. Switch the cations and balance out the charges to figure out what will be made. Important note: These reactions will only occur if both reactants are soluble in water and only one product is soluble in water. 5) Acid-base: This is a special kind of double displacement reaction that takes place when an acid and base react with each other. The H + ion in the acid reacts with the OH - ion in the base, causing the formation of water. Generally, the product of this reaction is some ionic salt and water: One example of an acid-base reaction is the reaction of hydrobromic acid (HBr) with sodium hydroxide: HBr + NaOH ---> NaBr + H2O If an acid and a base combine, it’s an acid-base reaction. The products will be an ionic compound and water. 6) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An example of this kind of reaction is the burning of napthalene: *Need an organic molecule:Carbon C10H8 + 12 O2 ---> 10 CO2 *a carbohydrate + 4 H2O If something that has carbon and hydrogen reacts with oxygen, it’s probably a combustion reaction. The products will be CO2 and H2O. Follow this series of questions. When you can answer "yes" to a question, then stop! 1) Does your reaction have two (or more) chemicals combining to form one chemical? If yes, then it's a synthesis reaction 2) Does your reaction have one large molecule falling apart to make several small ones? If yes, then it's a decomposition reaction 3) Does your reaction have any molecules that contain only one element? If yes, then it's a single displacement reaction 4) Does your reaction have water as one of the products? If yes, then it's an acid-base reaction 5) Does your reaction have oxygen as one of it's reactants and carbon dioxide and water as products? If yes, then it's a combustion reaction 6) If you haven't answered "yes" to any of the questions above, then you've got a double displacement reaction. 103
this shows the reactivity of metals and is used during single displacement. If potassium is mixed in a solution with other metals it will always replace the rest since it comes before all of them on this table. If B is higher than A, then it will not cause a reaction in single displacement if A is higher than B, then it will cause a reaction Both reactants must be soluble, and one product has to be soluble silver lead or mercury 1) NaOH + KNO3 --> NaNO3 + KOH Double Displacement 2) CH4 + 2 O2 --> CO2 + 2 H2O Combustion 3) 2 Fe + 6 NaBr --> 2 FeBr3 + 6 Na Single Displacement 4) CaSO4 + Mg(OH)2 --> Ca(OH)2 + MgSO4 Double Displacement 5) NH4OH + HBr --> H2O + NH4Br Acid-Base 6) Pb + O2 --> PbO2 Synthesis List what type the following reactions are: 104 7) Na2CO3 --> Na2O + CO2 Decomposition
