1. Matching Practice identifying the unique reactant(s) and product(s) of each of the 5 main types of chemical reactions by matching the characteristic to the correct type of chemical reaction. Synthesis Reaction Two or more reactants combine to create one large product. Single Replacement Reaction The reactants are an element and a compound and the element switches places with one of the elements in the compound to create the new products which are also one element and one compound. Combustion Reaction One of the reactants is always oxygen gas and the products always include water and carbon dioxide gas. Double Replacement Reaction The reactants are two different compounds and one element in each of the compounds switch places with each other to create the two new products that are also two different compounds. Decomposition Reaction One large reactant breaks down to create two or more products. 2. Sorting Sort each equation into the correct type of reaction. Synthesis H2 + O2 → H2O N2 + H2 → NH3 Decomposition KClO3 → KCl + O2 Ag2O → Ag + O2 Combustion C3H8 + O2 → CO2 + H2O C8H18 + O2 → CO2 + H2O Single Replacement Na + H2O → NaOH + ­­­H2 K + MgBr2 → KBr + Mg NaCl + F2 → NaF + Cl2 Double Replacement FeCl3 + NaOH → Fe(OH)3 + NaCl H2SO4 + NaNO2 → HNO2 + Na2SO­4 Pb(OH)2 + HCl → H2O + PbCl2 3. Write the word equation as a chemical equation potassium and chlorine combine to form potassium chlorideUse the subscript button to indicate subscript, and use the special characters button (9th button) to create an arrow. 4. Write the word equation as a chemical equation solid calcium hydroxide and aqueous phosphoric acid react to form aqueous calcium phosphate and liquid waterUse the subscript button to indicate subscript, and use the special characters button (9th button) to create an arrow. 5. Write the word equation as a chemical equation dinitrogen pentoxide is strongly heated until it decomposes into nitrogen and oxygenUse the subscript button to indicate subscript, and use the special characters button (9th button) to create an arrow. 6. Write the word equation as a chemical equation pentane undergoes a combustion reactionInclude state symbols for this reaction. 7. Balance the following reactions: 1Cl2 + 2NaBr → 2 NaCl + 1 Br22N2 + 5O2 → 2N2O51C3H8 + 5O2 → 3CO2 + 4H2O2C8H18 + 25O2 → 16CO2 + 18H2O1Pb(OH)2 + 2HCl → 2H2O + 1 PbCl21 H2SO4 + 2 NaNO2 → 2 HNO2 + 1 Na2SO­42NH₃ + 1H₂SO₄ → 1(NH₄)₂SO₄2 Al + 6 HCl → 3 H₂ + 2 AlCl₃
