1b. Give me the chemical name and chemical formula of the compound that produced this observation.
2. How did you know that the reaction stopped (that all the Potassium carbonate has been used up).
3. From your balanced chemical reaction, there were two more products besides the one that made the observation in Question 1 above. To separate those two products, what step (procedure) did you use? (Hint: what is the next step that you did in the lab after you reacted all the potassium carbonate)
4. Besides the crucible, what was the other substance that you had in the crucible for your final weighing?
Chemical name of this substance: _______________________
Chemical formula: _______________________
Phase (state) of matter: ________________
5. Was your actual /experimental yield (Circle one:) greater than, less than, or equal to your stoichiometric yield. Besides having weighing problems, give one explanation that the two yields were the NOT same.
