N#14 Types of Chemical Reactions • Single Replacement (Displacement) • Double Replacement (Displacement) • Decomposition • Synthesis • Combustion
element + compound compound + element Cl2 + 2KBr 2KCl + Br2 Re Single Displacement
Cl2 + 2KBr 2KCl + Br2 The anion(in this case) replaces Single Displacement Cl-
compound AB + compound CD compound AD + compound CB PbCl2 + Li2SO4 PbSO4 + 2LiCl Re Anions swap places Double Displacement
Decomposition See Pg 260 • compound two or more elements or compounds • Pb(OH)2 PbO + H2O
Synthesis • element/compound + element/compound compound • 2H2(g) + O2(g) 2H2O(g)
Combustion • hydrocarbon + oxygen carbon dioxide + water • CH4 + 2O2 CO2 + 2H2O
