Experiment 3: Chemical Reactions General Chemistry I and II Lab Manual Dakota State University Page 63 of 232 Experimental Procedure: WARNING: Wear your safety goggles, safety aprons, perform all tests carefully and follow any additional warnings that follow!!!!!!!!!!!!! REMEMBER! Be SURE to use CLEAN EQUIPMENT that has been THOROUGHLY rinsed with distilled water at least three times. Preliminary steps: Although we will not get to the single replacement reactions for a bit, we’ll start a couple early so they have time to react as these tend to be slow reactions. 1. Copper (Cu) Metal in Silver Nitrate (AgNO 3 ) After taking careful observations of both the copper metal and the 0.4 M silver nitrate solution, place the copper metal in about 1.0 mL of the solution in a SMALL test tube. Set aside and allow it to react undisturbed until called for later in this experiment. 2. Zinc (Zn) or Aluminum (Al) and Copper (II) Sulfate (Cu(SO

Set aside and allow it to react undisturbed until called for later in this experiment. Addition Reactions: 1. Cyclohexene (C 6 H 10 ) and Bromine (Br 2 ) DEMONSTRATION ONLY In the fume hood, you will see Cyclohexene and Bromine. Carefully take observations regarding these two reagents. Decide what color the mixture of the two should be if no reaction were to occur. (Your professor might be kind enough to show a mixture of a hydrocarbon that will not react with bromine as an example) Your brave and illustrious professor will add some of the bromine to the cyclohexene in the fume hood. Take observations. Did a chemical reaction occur?...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
