5 What is a Synthesis Reaction? 2 or more substances combine to form a single compound.2Na + Cl2 ----> 2NaClGeneral: A + B AB+
6 Knowledge Check: Which reaction is a synthesis reaction? 1. Fe + 2HCl --> FeCl2 + H22. 2Mg + O2 --> 2MgO3. 2H2O2 --> 2H2O + O24. NaOH + HCl --> NaCl + H2O
7 What is a Decomposition Reaction? A single compound breaks down to form two or more simpler substancesH2CO > H2O CO2General: AB A + B
8 Knowledge Check: Which reaction is a decomposition reaction? 1. Fe + 2HCl --> FeCl2 + H22. 2Mg + O2 --> 2MgO3. 2H2O2 --> 2H2O + O24. NaOH + HCl --> NaCl + H2O
9 What is a Single Replacement Reaction? One element takes the place of another element.Zn + 2HCl -----> ZnCl2 +H2General: AB + C AC + B++Zinc replaced hydrogen
10 What is a Double Replacement Reaction? 2 elements switch places to form new compounds.NaCl + AgNO3 ----> NaNO3 + AgClGeneral: AB + CD AD + CB++Chlorine and nitrate switch places
11 Knowledge Check: Which Reaction is Single …..….Double Replacement? 1. Fe + 2HCl --> FeCl2 + H22. 2Mg + O2 --> 2MgO3. 2H2O2 --> 2H2O + O24. NaOH + HCl --> NaCl + H2O
12 What is a Combustion Reaction? Oxygen combines with a substance and releases energy (heat and/or light)Examples:coal burning power plants firegas turbines and jet engines guns and explosivesPiston engines (cars)C(s) O2 (g) CO2 (g)General: A + O AO
