1. Sodium bicarbonate + Acetic Acid —> Carbon dioxide + sodium acetate + water                                 NaHCO3 + CH3COOH —-> CO2 + NaCH3COO + H2O (Combustion Reaction)
2. Calcium + water —–> calcium hydroxide + hydrogen gas                                                                     Ca + 2H2O —-> Ca(OH)2 + H2 (Single Replacement Reaction)
3. Dihydrogen dioxide —-> oxygen gas + water                                                                                         2H2O2 —–> O2 + 2H2O (Decomposition Reaction)
4. Calcium chloride + sodium carbonate —-> calcium carbonate + sodium chloride                                 CaCl2 + Na2CO3 —-> CaCO3 + 2NaCl (Double Replacement Reaction)

B. Some of the most powerful learning moments during the lab were being immersed in the French immersion classroom, and getting to work with the kids from elementary school.  I thought it was nice to have a French language refresher, and it was also nice getting to work with the kids since I don’t get to interact with younger kids on a regular basis.  Some of the most interesting discoveries I made while working with the younger students were seeing how they work, how they think, and how intelligent they are for their age.  The part of this shared learning experience that I enjoyed the most was getting to know what the kids like, their personalities, and getting to interact with them.
