separation of amino acids, carbohydrates, fats, vitamins, and more: Done for extensive research and even medical purposes. Thin Layer Chromatography (TLC) Thin Layer Chromatography is a chromatographic technique used to separate the components of a mixture using a thin stationary phase substance. It is operated similarly to paper chromatography. Materials Silica Plate, Tweezers & Gloves, Pencil & Ruler Unknown Dye (X), Unknown Dye (Y) & Unknown Dye (X & Y) 3 Pasteur Pipettes & UV Light…

The food that I ate from native American were Succotash which was from Narragansett and Akutaq which was from Eskimo of Alaskan Natives. I had both of them in the Native American restaurant, and the restaurant is quite old and classic. First, the Succotash was also called broken corn kernels and it contained sweet corn, lima beans and many other minor beans such as brown beans, red beans. The dish smelled healthy and beans flavor overwhelmed the smelling of the corn. However, the two main things…

breathed at a pressure above 1.4 atmospheres. According to Dalton’s Law, at what depth should a SCUBA diver be concerned about oxygen toxicity if he is breathing ordinary air? Discussion Points: • Dalton’s Law states that the pressure exerted by a mixture of gases is equal to the sum of the pressures that would be exerted by the gases individually. • Since air contains about 21% oxygen, so the pressure of oxygen at the surface is about 0.21 atmosphere.…

melamine in volume ratios of 1:1 and 1:3 to produce several mixtures as shown in table 2-1. The mixtures were dispensed into the de-ionised water to make solutions with a concentration of 1g/100ml. The solutions were then heated up to and kept at 80oC for 1 hour with constant stirring. This is to allow the melamine to fully penetrate and expand the graphite spaces. Later, the solutions were filtrated and dried for five hours at 80oC. The dried mixtures then underwent ball-milling to initially…

Fractional Distillation: Lab Report Mixtures can be seen just about anywhere. Mixtures are a substance made of two or more substances. A substance is a particular kind of matter that is uniform throughout. When these substances are mixed together and only mix physically and not chemically, like in a reaction, they are mixtures. Due to these properties, the substances within the mixture can be separated again. Mixtures are separated by one of many separation techniques. Take filtration of tap…

bowl add the sour cream, soup and cheeses and the chicken, stir well together. 2. Combine the noodles into the mixture until fully coated. 3. Take a 9x13 lightly greased baking dish and pour in the mixture. 4. Combine the margarine and crackers then sprinkle over the mixture. 5. Spread the poppy seeds evenly over the top. 6. Preheat your oven to 350 degrees then bake the mixture for…

overwhelming. With a new harvest comes new preserves, and my favorite one of all, bread and butter pickles. *It does not matter what size of cucumbers that I pull out of the garden to make the pickles because I will be slicing them to put in the mixture. The important thing to keep in mind is that I will need to have 16 cups of sliced cucumbers which means, at least a dozen medium to large cucumbers. Once I choose the cucumbers and place them in my large orange bowl that I brought out to…

ABSTRACT: In this experiment, we determined the relative polarity of substances using the principles of chromatography. Three substances were tested using a thin layer chromatography. The column chromatography tested a mixture of two substance which were separated as a result of the chromatography. The results for both the thin layer and column chromatography supported the hypothesis. Therefore, chromatography is an effective tool that can be used to determine relative polarities. INTRODUCTION:…

temperature may vary from 123⁰C (under reflux) to 160⁰C (bake). Dyes from substituted naphthalenes: Brown dyes of this type include C.I. Sulfur Brown 7,15,16,31,63. Sulfur Brown 15 is obtained by Obtained by baking a mixture of 138 parts of 1,5-dinitronaphthalene and 75 parts of crude cresol with sodium polysulfide, in the presence of copper sulfate and sodium chloride at 265⁰C for 12-14 hours. The 1,5-dinitronaphthelene may be reduced at 95⁰C with sodium…
