Using your understanding of these lab and your lab notebook, answer the following questions in the space provided.
1. In the Observation of a Chemical Reaction Lab, was the Aluminum chloride solution part of filtrant or filtrate? ________________
2. In the Endoexothermic Reaction lab, what was the gas that was formed, give the chemical formula in the space provided. ________________
3. In the Observation of a Chemical Reaction lab, which observation of a chemical reaction that you observed actually was not caused by the chemical reaction? ____________(Do not have to explain why).
4. In the Endoexothermic reaction lab, did all the reactants react in the lab or was there some unreacted reactant left after the chemical reaction stopped? How do you know or how do you don't know? Explain.
5. For the Observation of a Chemical reaction lab, If you still had a blue color to the filtrate (the solution that goes through the filter paper), what does it mean and how can you fix it?
6. In the Observation of a Chemical reaction lab, what happened to the material/substance/particle that caused the solution to be be blue (i.e. what did it become)?
7. Answer this question on back side of the paper.
For the Endoexothermic lab. you did the following for an Endothermic reaction. Here please do the following but of an EXOTHERMIC instead.
Draw the potential energy diagram for a EXOTHERMIC reaction. Label/show the following:
- Potential energy of the reactant (write chemical symbols of them)
- Potential energy of the product (write chemical symbols of them)
- Graph axes
- Potential energy of the activated complex
- Activation energy
- Heat of reaction and indicate its sign ("+" or "-")
