Types of chemical reactions

The web resource http://learningchemistryeasily.blogspot.com/2013/01/types-of-chemical-reactions.html  gives a graphical description of the different types of reactions explored to this point. Think about the compound sodium bicarbonate. Which of the five different types of reactions is your compound involved in? Include information about heats of reaction and comment on whether the reaction is endothermic or exothermic and how the magnitude of this energy change compares with other reactions. Post an example of a reaction and describe what type it is and why.
