1 Types of Chemical Reactions

2 Combination/Synthesis Reaction
General Equation: R + S  RS Reactants: Generally two elements or two compounds. Probable Products: A single compound Example: 2Mg(s) + O2(g)  2MgO(s) Practice problems pg 214 #13-14

3 Decomposition General Equation:
RS  R + S Reactants: Generally a single binary or ternary compound Probable Products: Two or more elements Example: 2H2O(l)  2H2(g) + O2(g) Practice problems pg 216 #15-16

4 Combustion General Equation:
fuel + O2  CO2 +H2O Reactants: A compound of C, H, (O) and oxygen Probable Products: Carbon dioxide and water Example: 2C3H8O(g) + 9O2(g)  6CO2(g) + 8H2O(l) Practice problems pg 221 #20-21

5 Single Displacement General Equation:
R + TS  RS + T Reactants: An element and a compound. For displacement to occur, the element that is displaced must be less active than the element that is doing the displacing. Probable Products: A different element and a new compound Example: Zn(s) + 2HCl(l)  H2(g) + ZnCl2(l) Practice problems pg 218 #17

6 Double Displacement General Equation: Reactants: Two ionic compounds
RU + TS  RS + UT Reactants: Two ionic compounds Probable Products: Two new ionic compounds Example: Na2CO3 + CuSO4  Na2SO4 + CuCO3 Practice problems pg 220 #18-19
