Chem 101 Discussion Board for Science Salon Flaming Swedish Fish (Thanks Katie and Hillary!) Here is the reaction today: The reaction was heated until the KClO 3 decomposed. 2 KClO 3 (s) ------> 2 KCl (s) + O 2 (g) The Swedish fish was dropped in and a combustion reaction occurred. C 12 H 22 O 11 (s) + 12 O 2 (g) -------> 12 CO 2 (g) + 11 H 2 O(g) 1. Which compounds in the two reactions are ionic and which are covalent? What are the cations and the anions in the ionic compounds? 2. C 12 H 22 O 11 (s) is sucrose (you may recognize the formula!). What is the role of the KClO 3 ? If I torch a gummi candy with a propane lighter, does it burn the same way? Could I do this experiment with molten NaCl?

Unformatted text preview: 3. What is the smoke? Why is there so much of it? The smoke didn’t seem to linger. Where did it go? 4. You are going to learn how to draw molecules on Friday. You need the total number of valence electrons to draw correct Lewis structures. How many valence electrons does each of the molecules have in which to make covalent bonds? (You might want to figure out sucrose last!) 5. If a gummi bear is used in this experiment, then we name it the Growling Gummi Bear. Name this experiment if a pumpkin Peeps is used. (No off-color naming! Just be BYU creative!)...

    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.
