1. List each of the mixtures of reagents that you tried and your observations. - Bleach + Luminol: turned orange-brown; got thicker, grainy; did not glow, did fizz - Dimethyl Sulfate + Luminol: luminol did not dissolve; did glow - slightly yellow - Hydrogen Peroxide + Luminol: turned yellow, cloudy towards top; did not glow - Sodium Hydroxide + Luminol: no color change; did glow - white - Hydrochloric Acid + Luminol: clouded; did not glow - Air + Luminol: yellow powder; did not glow - DMSO + Sodium Hydroxide + Luminol: initially mixed - gel-like appearance; glowed and was warm - DMSO + Sodium Hydroxide + Bleach + Luminol: glowed quickly and bright blue 2.

Unformatted text preview: DMSO, Sodium Hydroxide, Luminol, Bleach when combined with others 3. Which reagents extended the life of the chemiluminescence reaction? DMSO, Sodium Hydroxide, Luminol 4. What was the longest chemiluminescence time? Combinations with DMSO, Luminol, and Sodium Hydroxide did not fade during the time of this experiment. The reaction with those three and bleach was the shortest. 5. What do you think is causing the chemiluminescence? Chemiluminescence is a reaction caused by two chemicals mixing together into a high-energy, unstable state, then breaking down and releasing the energy as photons of light....

    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.

    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.
