Leah Romero 10/30/2017 Conclusion Lab 3 Chem 102L In lab 3, fundamentals of chromatography, the purpose was to examine how components of mixtures can be separated by taking advantage of different in physical properties. A huge process in this lab was paper chromatography, which was used to isolate food dyes that are found in different drink mixes. The different chromatograms of FD&C dyes were compared to identify which dyes are present in each of the mixes. Chromatograms where made for the known FD&C and for the three Kool-Aid samples. The retention factor for each dye was calculated.
For TLC profiling, 4 TLC plates were prepared for the testing of each solvent. As shown in Figure 1, the green food dye was placed at the bottom center, specifically 0.5 cm away from the bottom of the plate, with the use of a capillary tube. Each one of the silica plates were then vertically placed in a small beaker with its inside surrounded by a filter paper saturated with the solvent to be tested and a small amount of the same solvent at the bottom. The TLC plate was then taken out when the rising solvent was about to reach the top of plate. The ammonia: 1-butanol solvent was tested 7 times due to some personal
Glazed Pork Chops Serves: 4 Ingredients: • 4 large pork chops • 2 tablespoons pure maple syrup • 1 tablespoon grass-fed butter • 1 tablespoon coconut oil • Sea salt and ground black pepper Instructions: 1. Rub both sides of each pork chops with salt and pepper. 2. Melt coconut oil and butter in a frying pan over medium-high heat. Add pork chops and cook each side for 5 minutes until nicely browned and internal temperature reaches 155 degrees.
The Campbell's Soup Cans Is one of the famous works by Andy Warhol that is produced in 1962, which is sometimes referred to as 32 Campbell's Soup Cans. First showed in the Ferus Gallery of Los Angeles, California on July 9,1962. It consisted of 32 canvases and each of them consists of canned soup company. Andy Warhol, the famous and successful artist used printmaking method and screen-printing in this painting. The Campbell’s Soup Cans was based on a popular culture, which is pop art.
Materials: 20 whole large and small lima beans were used in this experiment as well as two petri dishes. An aspirator was used to suck each Callosobruchus maculatus out of the large plastic tube in order to insert each of them into the petri dishes. Procedure: In order to carry out this experiment two different sized lima beans were needed. Two plastic containers that have plastic dividers were utilized to split the container into four sections. The two plastic containers were divided to which one contains which bean size.
This artwork was a piece made by the American artist Andy Warhol. It was a part of a collection called Campbell’s soup cans and was made in 1962.the artwork consists of 32 paintings put together. This artwork became so popular mainly because pop art was becoming popular and Andy Warhol took control of it. He chose Campbell’s soup because he needed a new subject after he abandoned comic strips. He also chose it because it was simple and easy.
1. What type of macroscopic evidence for chemical change did you observe during this experiment? Give at least three different examples. (15 points) Example 1: The baking soda (NaHCO3) mixed with vinegar (CH3COOH) created foam as well as the washing soda (Na2CO3) when mixed with the vinegar. Example 2: The color change when the starch and iodine (I2) mixed.
Living inside a painting Art is a very strong way to express feelings, emotions, and thoughts. Wayne Thiebaud is known for his very famous paintings such as, pastries, cakes, pies, toys, etc. Wayne will always be known for his still life artwork. The title of this famous artwork is called Valley Streets, which was created in 2003. The mass is in 2D being that it is flat on a canvas.

The natural agar consist of Yeast Extract, Tryptone , Lactose , Manniiol, Sodium Chloride , Dip otassium Hydrogen Phosphate ,Gelatin and Agar .Then , in a conical flask 14g of nutrient agar was mixed into 500 ml of distilled water and , The mixture was stirred and dissolved until most of the agar dissolve. By non-absorbent cotton wool plug the mouth of the flask was closed. By using the autoclave the agar was sterilized for 15 minutes.The cotton wool was removed. By the flame the mouth of the flask was heated before and after pouring the agar into the Petri dishes. And, the left hand the lid of the Petri dish was lift, just enough to enter the mouth of the flask and quickly was poured in agar (about 15 cm3).
Description Andy Warhol constructed the painting ‘32 Campbell’s Soup Cans’ in early 1962. The exclusive frames are lined flush four by eight alongside the other relative canvases. Each enclosed structure is approximately 20 inches by 16 inches. Piece by piece, the Campbells Soup Cans were individually painted with a different assortment of flavors, listing of the top left corner with a tomato soup can thoroughly to the bottom right corner ending with turkey vegetable soup. The series of Campbell’s soup cans exposes each type of soup.
32 100 μL of afore-prepared sample solution and the mixed reference standard were diluted 100 times with ethyl acetate. 50 μL of these dilution solutions were separated on the TLC plate coated with SNISG. The plate was developed with petroleum ether: ethyl acetate (4:1) and the movement of solvent was usually controlled at 1 cm from the upper edge. After completion, the plate was dried until no solvent smell remained. It was sprayed with an ethanol solution containing 10% sulfuric acid, and heated at an infra-red drier until obvious color came up, as shown in Fig.2 (B.ab).
