A2. A scientist has a beaker of water. She adds 10 ml of sunflower oil into the beaker of water and stirs it. The water becomes cloudy, then gradually clears as an oily layer forms on the surface. The structure of sunflower oil is shown below: o O What is happening here? Why does the oil behave this way in the solvent water? Draw diagrams of chemical structures and use thermodynamic terms and equations to...

1. Name at least 3 ways you can control the amount of light that reaches the ocular lens. 2. Define resolution. What is the limit of resolution for the light microscope? 3. What effect does the wavelength of light used have on resolution? 4. If you view a bacterial smear under the oil immersion lens, but forget to add oil, will the image still be just about as clear as if you had added the oil. 5. Define parfocal. 6....

What is the SN2 reaction? How does Br attach to which carbon as
a nucleophile and why? Difference between Unimolecular or
Bimolecular? How NaBr and H2SO4 work in the
reaction? Why Water/Sulfuric Acid/Brine/Sodium
Hydroxide/Na2SO4 in Extraction? What does
each layer have inside in each step of the separation?
Please help. Due to corona, this is a theoretical lab and I am
very confused.
