In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen

In the predation lab‚ my partner and I simulated the relationship between predators and prey in an ecosystem. To do this‚ we took 3 white squares‚ which represents the prey‚ and put them on a sheet of paper‚ which represents their ecosystem. We then took 1 larger pink square‚ that represented the predators‚ and let it fall onto the white squares. For the predators to be able to survive in the ecosystem‚ the pink square had to land on at least 3 white squares‚ and it also needed to land on 6 squares

It prevents contamination from unknown cultures. 3. Does your lab report contain any messages when your inoculation was not complete? What change in the traffic signals indicates an unsuccessful inoculation? Answer: The lab report does not contain any messages about inoculation. There’s only a reference if auto-inoculation was used. The traffic signal light will turn red if the inoculation was unsuccessful. 4. Does you lab report contain any messages when you don’t follow aseptic procedures

Lab 2: Equipotential Lines and Lines Of Force Purpose: The purpose of this lab is to find the electric current when passing through conductors of different shapes and sizes. Also to gain a general knowledge of the laws governing the flow of current through extended conductors is another objective for this experiment. In this lab we are to experiment with the lines of force and equipotentials. We are also to find out vector field and the relationship between the lines of force and the electric field

(dialysis tubing). The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration in the attempt to reach homeostasis in different circumstances. Introduction: The main purpose of this lab was to observe diffusion and osmosis. This is demonstrated using dialysis tubing and a combination of monosaccharaides‚ disaccharides‚ water (H20)‚ and sodium chlorine

points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance‚ then plotting heating and cooling curves and analyzing them. Data that you collect will represent the

this recrystallization lab in order to achieve the desired results‚ which included heating the solvent‚ completing a hot filtration‚ completing a vacuum filtration of a chilled solution‚ as well as drying and calculating the weight and melting point of the final version of the sample. I began the lab with 1.5 grams of the impure acetanilide solute and ended the lab with 0.05 grams of pure acetanilide crystals. The percentage of pure acetanilide I recovered during this lab was 3.33%‚ which is lower
