3. You make a solution that contains 1000 molecules of water. 90 molecules of glucose, and 120 molecules of sucrose. What is the solute concentration of this solution? (2 points) 17.35/ 4. You now add a cell into the solution from question 3. This cell has a 20% solute concentration. a. Is the outside of the cell hypertonic, hypotonic, or isotonic when compared to the inside of the cell? How do you know?...

vided in the notes? Experiment 8.3: Light and Photophosphorylation Now that you have determined which wavelengths of light are absorbed by the different plant pigments, it is time to determine which wavelengths of light are most effective in stimulating photophosphorylation. Students are provided with different colored cellophane (thin, transparent sheets made from regenerated cellulose) filters. These filters contain pigments that absorb some wave- lengths of light and transmit others. The wavelengths transmitted are those associated with the color seen. The...

Experiment 6. the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents....

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
