Chemical Equations General Reactants Products Word Equations Oxygen + Hydrogen = Water Skeleton Chemical Equations O 2 + H 2 H 2 O Balanced Equations O 2 + 2H 2 2H 2 O Diatomic Particles List H 2 , N 2 , O 2 , F 2 , Cl 2 , Br 2 , and I 2 Chemical Reactions Types of Chemical Reactions 1. Synthesis More than one substance (reactants) becoming only one single product. A + B AB O 2 + 2H 2 2H 2 O 2. Decomposition (opposite of synthesis) Breaking up a single substance into more than one product. AB A + B 2H 2 O O 2 + 2H 2 3. Single Displacement/Replacement* A + BC AC + B Zn + CuSO 4 ZnSO 4 + Cu 4. Double Displacement* AB + PQ AQ + BP 2KI + Pb(NO 3 ) 2 2KNO 3 + PbI 2 Neutralization is also double displacement. HCl (aq) + NaOH (aq) H2O + NaCl 5. Combustion of Fuels CH 4 + 2O 2 CO 2 + 2H 2 O Complete Combustion CH 4 + ?O 2 C,CO, CO 2 + H 2 O Incomplete Combustion 6. Redox Reactions Reduction and oxidization of substances take place. Zn + 2HCl ZnCl 2 + H 2 (Reducing Agent/Loses Electrons) + (Oxidizing Agent/Gains Electrons) Products * In displacement, the more reactive one replaces the less reactive one Biological Catalysts In biology catalysts are very important in sustaining life. Enzymes are biological catalysts. Inhibitors are chemicals that slow down reactions.
