9.08: lab: dissolving metals
1. in which cups did a chemical reaction take place? explain your answer. (2 points)

2. did the galvanized nail in this activity behave similarly to the galvanized nail in lesson 4, testing and producing gases, when muriatic acid was added to it? explain. (2 points)

3. were any gases produced in the cups when the copper sulfate solution was added to them? (2 points)

4. what did you notice about the color of the copper sulfate solution before it was added to the metals and after? the color in the copper sulfate solution comes from the copper ions that are present. with this information, what substance would you speculate was formed in the reactions that took place? (2 points)
5. with this information, what substance would you speculate was formed in the reactions that took place?
(hint: remember that no new elements can be formed in a chemical reaction. instead, all products must be formed from the elements that were present with the reactants.) (2 points)

conclusion (2 points)
write a two- or three-sentence conclusion to summarize what this activity showed about how the different metals react with the copper sulfate solution.
