Consider the following chemical reaction:. CuSO4 (s) + heat - - > CuO (s) + SO3 (g). Design an experiment in which you use this chemical reaction to test the law of mass conservation

The first step is to measure mass of crucible and its cover. Then put CuSO4 (s) in the crucible with lid and again measure its mass. Heat until the bottom of the crucible turns red. Measure mass after cooling it. Remove cover and heat for one minute. Change cover and measure mass again. Calculate for the mass lost and compare it with the theoretical mass loss based on the equation.

At the start of the experiment, it is important to measure the weight of the crucible along with its lid. Now again measure the crucible with lid along with CuSO4. The third step involves heating the crucible along with CuSO4 with the lid until the bottom turns red in color. Allow it to cool down and then measure the mass again. The fourth step involves removing the lid and heating the crucible for approximately a minute. Now change the cover, put a fresh cover and measure this mass. It will give you the mass that is lost and compare it with the theoretical mass to get to the answer.
