Chemical Reactions

1. Observe a demonstration of the reaction of HCL +NaHCO₃ to produce Co₂ + H₂0 + NaCl

2.Use atom tiles to create representations of the reactant molecules and rearrange them to make product molecules. When they are satisfied that they have re-created the reaction, they write a balanced chemical equation for the reaction, using standard conventions.

3. Prepare to evaporate the water from the salt and the Calcium Carbonate from the water in the Limewater test for Carbon Dioxide
