    Two chemicals react to generate a new chemical in a combination reaction. A combination reaction is nearly always an exothermic reaction.

    The combustion process is one example of a combination reaction.

    When barium interacts with fluorine, however, Barium Flouride is formed, which is a highly exothermic reaction.

    The reactions in which atoms or molecules combine to generate a product are known as combination reactions.

    The majority of reactions involving combinations are exothermic.

    For instance:

    Magnesium oxide reacts with carbon dioxide to generate magnesium carbonate, releasing heat in the process because this is an exothermic reaction.

    MgO + CO2 MgO + CO2 MgO + CO2 MgO + CO2 MgO + CO (CO3)2

    Calcium oxide (quick lime) interacts with water to form calcium hydroxide and a lot of heat.

    Ca(OH)2 + heat + CaO + H2O
