- - - - Single Replacement Ex:
        Ca+ HCl= CaCl+ H
        (only one switched places with another).
        
        Double Replacement Example: CaBr2 +Na2CO3 = CaCO3 + 2NaBr (two reactants, two products)
        
        Combustion Example: Organic Compound + O2 = CO2 +H2O (Reactant must have an organic compound C or H; Product must be CO2 + H2O)
  - - - CaCl2+NaF-->NaCl+CaF2
        
        1Ca, 2Cl, 1Na, 1F, 1Na, 1Cl, 1Ca, 2F
        
        since the Na and F elements aren't balanced, you have to multiply by 2 to balance them out
        
        now become 1Ca, 2Cl, 1Na, 1F, 1Na, 1Cl, 1Ca, 2F
        
        Final balanced equation:
        CaCl2+2NaF --> 2NaCl +CaF2
