CHE115 31 Tear this page out of your laboratory manual and submit it to your TA with your answers. B. Post-Lab Assessment Questions: (30 pts) 1. (18 pts) For each mini experiment, make a list of all the chemical reactants you components that you mixed together in each mini used. These are the experiment to cause a chemical reaction. (4 pts) A student makes observations when water is added to a blue solution of copper sulfate. The student makes only 1 observation: the solution changes to a lighter shade of blue. Is this an example of a chemical reaction? Explain your 2. reasoning pts) Tums is a well-known antacid used to cure an upset stomach usually caused when your stomach contents become too acidic. Which one of the mini- experiments that you completed today do you think is most similar to the chemical reaction that occurs in your stomach when you take a tums tablet to neutralize the excess acid? Explain your reasoning. 4. (4 pts) In the lab today you observed 9 chemical reactions, one in each of your mini experiments. Choose 2 of the mini experiments and try and predict the products that were formed during the chemical reaction that occurred. You might even try and write the balanced CHEMICAL EQUATION. If you haven't yet learned how to predict the products and write balanced chemical equations, use a book or the internet to help you find the answer. This may feel odd, but remember that scientists look up information all the time. Learning to search for information is an important skill to learn.
