Using a dry spatula, transfer approximately 1 gram of ‘Baking soda, sodium hydrogen carbonate (NaHCO3)’ into the test tube. Using the same scale, find the exact mass of ‘test tube, beaker and Baking soda’. Record all the digits. Mass of the ‘Baking soda’ should be no more than 1.500 g. Clamp the test tube at the neck.

We used quantitative data to determine which of the four given equations best fit the thermal decomposition of baking soda. Our plan to conduct the chemical reaction was to begin with 2g of baking soda in a crucible, place it over a flame from a Bunsen burner for 5 minutes (until the chemical reaction was complete), then measure the mass of the resulting product.
