    Study Notes

    Chemical Bonds and Reactions

    • During a chemical reaction, chemical bonds are broken and formed.
    • The type of bond formed in a Lewis acid-base reaction is a covalent bond.

    Energy and Bond Formation

    • When the energy required to break bonds is larger than the energy evolved in making new bonds, the net result is an endothermic reaction.

    Lewis Bases

    • An example of a Lewis base is ammonia (NH3).

    Classification of Chemical Reactions

    • Chemists classify chemical reactions into different categories, including synthesis, decomposition, single displacement, and acid-base reactions.
