Synthesis Mg + O2--->H2 + O2--->K + Cl2--->Fe + O2--->
Decomposition • AlCl3 (l) • HgO • H2O • MgCl2 • FeS
Decomposition Video (NH4)2Cr2O7
Combustion • Reactants • Hydrocarbon (ex. CH4) • Oxygen • Products • Carbon dioxide • Water
Activity Series An atom can NOT replace an atom that is above it!
Single Replacement • FeI2+Pb • FeI2+Cl2 • Br2 + NaF • Fe + CuSO4
For a reaction to occur a product must be insoluble or water. Soluble = aqInsoluble = s
Double Replacement KOH + H2SO4 FeS + HCl NaCl + H2SO4 AgNO3 + NaCl
