The last for your concideration bulet question.

3 5. 2. 9. OFF Figure 2.7 Drying a solid in an evaporating dish 19. Remove the evaporating dish from the beaker and allow the dish and its contents to cool to room temperature. Dry the dish and determine the mass of the dish and its contents. Record the mass. 20. Discard your SiO2 following the directions of your laboratory instructor. Data Analysis Determine the mass of each component in your original sample. Calculate the percentage of each component in the mixture. For Your Consideration Why should one never weigh a hot object? Why can filtration not be used to separate the components of a salt water mixture?- What mistakes in performing this experiment could cause the following errors: The reported percentage of NaCl in the mixture was less than the actual value. The reported percentage of SiO2 in the mixture was more than the actual value. How could you separate the components of a mixture of CaSO4 and Ca(NO3)2 and recover the two separated substances? 2-6
