- Students should be able to do division and multiplication, or have access to a calculator.
- Previous exposure to chemical reactions would be beneficial, but is not required.
- Stoichiometry is the quantitative balancing of elements in chemical reactions.
- Conservation of mass requires that all atoms that enter a reaction as reactants must exit the reaction in the products.
- The Ideal Gas Law is used to model equilibrium conditions of most gases, relating the pressure, volume, temperature, and moles of gas.
- 1 clear jar (You will need to use a measuring cup to label volume measurements along the side of the jar.)
- Measuring cup
- Measuring spoons (only ¼ tsp and ½ tsp are necessary)
- Small plastic sandwich bag
- 1 large bucket/tub (14.5” length x 12.2” width x 9” depth is an absolute MINIMUM size – use a considerably larger one if possible)
- 1 empty 20 oz. Gatorade bottle
- 2 cups of vinegar
- ¾ tsp baking soda
- Water source
