    Reaction types

    • Synthesis reactions have one product.

    • Decomposition reactions have one reactant.

    • Single replacement reactions have an element and a compound as reactants and products

    • Double replacement reactions have two compounds as reactants and products.

    2S + 3O2 ---> 2SO3 .... one product.... synthesis

    2Na + 2H2O --->2 NaOH + H2 .... element and compound ... single replacent

    2H2O2 ---> 2H2O + O2 ..... one reactant ... decomposition

    CaCl2 + F2---> CaF2 + Cl2 .... element and compound .... single replacement
