Toxic) (an ionic compound); the tip of a spatula full (about 0.1 g) (3) table sugar (sucrose, a polar covalent compound); the tip of a spatula full (about 0.1 g) (4) Naphthalene (CAUTION! Toxic, flammable, toxic fumes) (typical ingredient of urinal cakes; a non-polar covalent compound); the tip of a spatula full (about 0.1 g) (5) Ethylene glycol (CAUTION! Toxic)(typical ingredient in antifreeze; a polar covalent liquid); about 3 drops (enough to see) (6) Paraffin Oil (CAUTION! Toxic, flammable) (a non-polar covalent liquid); about 3 drops (enough to see) Agitate each solution by flicking the test tube. Describe what happens in each. Effect of Temperature on Solubility:Using a clean beaker, begin heating about 50 mL of distilled H2O. Place each of the following into three medium sized test tubes: (1) 2 g potassium sulfate K2SO4(CAUTION!

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.
Temple University Fox School of Business ‘17, Course Hero Intern
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.
University of Pennsylvania ‘17, Course Hero Intern
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.
