Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4

The premises of "Trump immigration policies disrupt health care: Column." is the constant lack of physician shortage that the United States has faced. This is not just a current problem‚ getting trained physicians to help in poor urban areas has been a problem for decades. Preisedent Trump’s new travel ban has blocked thousands of Visa holders from entering the country or causing a delay upon their arrival. Foreign doctors have helped in rural urban areas because they came to the US to recieved other

Chapter 9 closing case Ashford University BUS 650 Managerial Finance When should Bunyan Lumber‚ harvest the forest? The cash flow will grow at the inflation rate of 3.7%. Utilizing the real cash flow formula (1+R) =v (1+R)(1+H) 1.10 = (1+R)(1.037) R= 6.08% The conservation funds are anticipated to grow slower than the inflation rate. The return for the conservation fund will be‚ (1+R) = (1+R) (1+H) 1.10 = (1+R) (1.032) R= 6.5% The cash flow from the thinning process is as follow

Discussion: The two dyes identified were disperse blue 3 and disperse red 9. Disperse red 9 separated first because it is less polar than disperse blue 3. This is due to the structure of disperse red 9 being more symmetrical than that of disperse blue 3 and having more nonpolar bonds. Disperse blue 3 is more polar because it has a hydroxide bond and has a larger dipole. The principle behind using column chromatography is that it separates compounds based on polarity. The alumina serves to allow

Organizational communication Reading reflection: CH-9 communicating gender at work This reading touched down on three feminist perspectives that can be used to further understand power relations within organizational life. The three perspectives are liberal‚ radical‚ and critical feminist. The author argues that the critical feminist perspective is the better one of the three to use while looking at organizational communication in relation to power. In the later part of this reading masculinity

Paper chromatography is a useful technique for separating and identifying pigments and other molecules from cell extracts that contain a complex mixture of molecules. The solvent moves up the paper by capillary action‚ which occurs as a result of the attraction of solvent molecules to the paper and the attraction of solvent molecules to one another. As the solvent moves up the paper‚ it carries along any substances dissolved in it. The pigments are carried along at different rates because they

Chapter 6 Perfectly Competitive Markets 1. A firm sells a product in a perfectly competitive market‚ at a price of $50. The firm has a fixed cost of $30. Fill in the following table and indicate the level of output that maximizes profit. How would the profit-maximizing choice of output change if the fixed cost increased from $40 to $60? More generally‚ explain how the level of fixed cost affects the choice of output. The table is as follows: Output (Units) Total Revenue ($/unit) Total Cost ($/unit)

curvature in the neck‚ upper trunk and lower trunk is normal. Humans need these spinal curves to help the upper body maintain proper balance and alignment over the pelvis. However‚ when there are abnormal side-to-side (lateral) curves in the spinal column‚ we refer to this as scoliosis. Scoliosis occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy‚ the cause of most scoliosis is unknown. Scoliosis
