Procedure: Part A: Extraction stage 1. Place a 125 mL separatory funnel in a ring stand equipped with a small ring. 2. Heat the hot plate. 3.…
Then the mass of a weighing dish was recorded along with 0.35 g of KHP. The mass of an Erlenmeyer flask was then weighed as well. After both flask and substance were weighed, the combined mass of the flask and substance was recorded…
The experiment was to observe if the difference in the amount of acid added affected the mass of the curd by either increasing or decreasing the…
DISTILLATION The purpose of experiment 1, fractional distillation and gas chromatography, was to separate an unknown organic mixture into two liquids. The primary process of separation was fractional distillation, which utilizes the physical properties of the two unknown volatile liquids. Once the unknown mixture was successfully fractioned, gas chromatography was used to help determine the identity of the two unknown liquids. Fractional distillation and simple distillation both take advantage of two major physical properties to separate liquids.…
CONCLUSION: Two weeks ago, Soundings XVI performed Lab Experiment Number Two. Lab Experiment Number Two was similar to the previous, Lab Experiment Number One. The prompt was to compare the results of pennies dropped in water, versus the result of pennies being dropped into milk, both at 100 mL. The main purpose of this lab was to further discuss more scientific parts of this lab, such as the surface tension when the cylinder was close to overflowing for both the milk and water. Before performing this lab, my group and I created a hypothesis to reflect upon and to state what we believed would dictate the results.…
The balance had an uncertainty of 0.05 grams. b. With this experiment, we had a closed environment within the vial, not allowing any particles to come in or out, further explaining why there was no change in mass. The experiment also did not cause a visible reaction. The system was the vial, cap, water, and sugar. c. 2.…
Monforte Dairy started with Ruth Klahsen and Sebastiano Monforte back in January 2003. Since inception, the company has faced extreme financial troubles which have restricted Monforte’s prospects for future growth. The company is in desperate need of a capital infusion in order to attract more customers and maintain market share. Klahsen has pledged her personal assets and has attempted different micro financing options like the Community Shared Agriculture initiative. Yet still, unfavorable lease obligations have caused a burden on Monforte’s ability to focus on their core competencies.…
When beginning the experiment we observed and recorded the appearance of the materials in use like instructed. We weighed our materials out on a tared scale and placed them all in their corresponding test tube. We mixed and centrifuged our solution all three times for the appropriate times and decanted them accordingly. After getting all our liquid we heated up until a white solid formed, waited for it cool…
Got milk? Well, Douglas Meeks did, before his cup of milk went dry and later turned into a spoiled solid. Presenting his peculiar findings in the form of a science fair project at the Palo Verde Unified School District Science Fair, Meeks, a 4th grade student at Margaret White Elementary won 1st place overall and best in show for grades 1st-8th, which also led to his project being sent to the Riverside County Science Fair.…
Soured Milk Problems 1.The Southern Steakhouse’s senior management decided to open a fifth location in Hamilton when the fourth location was already failing to produce the desired revenues. 2.Maxim and Schultz identified the performance appraisals as a waste of time, and then re-performed the same activity merely a week later. 3.Maxim and Schultz gave Michelle Rodes special treatment by letting her skip parts of their mandatory hiring process, such as the formal interview, before hiring her. 4.Maxim and Schultz gave Michelle Rodes special treatment by allowing her to skip the restaurant’s mandatory, extensive training program.…
Molar Volume of a Gas Lab The purpose of the lab was to do an experiment to determine the molar volume of hydrogen gas at standard temperature and pressure, or STP. To start the experiment, a beaker was filled with water and then a cage was created with a copper wire. A piece of magnesium was cut and placed inside the cage in order to keep the reaction going until all of the magnesium reacted with the hydrochloric acid. The eudiometer tube was filled with 15 mL of hydrochloric acid and water and then plugged with a one-hole rubber stopper that held the cage in place, ensuring that the magnesium would react with the excess hydrochloric acid.…
A possible error that may have been encountered is that the group forgot to zero out the cup while measuring the masses of the materials, therefore including the cup’s mass in the group’s measurements and causing an apparent increase in…
The next step is to allow the milk mixture to stand for about 15-30 minutes. After the allotted time has passed, perform the straw test to determine if the mixture (gel) is firm enough. To determine whether the gel is firm enough, test the mixture using a drinking straw. Place the straw vertically into the mixture and then cover the top hole with a finger. Lift the straw out of the mixture, still covering the hole with a finger.…
Question 1: A. In evaluating a company should an investor rely more on accounting profits or cash flow An investor should give his or her decisions basing on a statement of cash flows because: The greatest difference between profits and cash flows is that profits data use accrual accounting, while cash flows base on real figures. Precisely, profit data will be recorded in the current period regardless of a company received money or not. Meanwhile, the other expenses such as wages, interest and rents must be paid by cash.…
PURPOSE We used chemical indicators to identify possible sugar, starch, protein, and lipids present within two common food items as well as the dead Anna Garcia’s stomach contents. HYPOTHESIS If Anna ate foods like pizza, ice cream, and Oreo cookies like she said on her food log, then her stomach contents should react with the chemical indicators for glucose, maybe starch due to the pizza.…
