12 Grams Of Oil Lab Report

Procedure- The procedure for this lab includes many simple steps and a few different things we are testing. Our first Procedure was to combine water and salt to see what kind of reaction it would make. First we fill the graduated cylinder with 100 ml of water. We then measured 1.0 grams of table salt on a balance to get an accurate amount. After, we took the measured amount of salt and poured it into the water filled beaker. Lastly, we watched and recorded the reaction.

October 17, 18, and 19, samples were collected from multiple sites along the BSR. The class was split into groups, and samples were collected from seven separate locations along the river and WWTP. There was also a sample collected by the S which is located between sites four and five. For each of these sites, there were ten groups from other labs that also collected a sample from the BSR. At site two of the river, the location included multiple sources of possible contamination. A drainage site was located 200 yards upstream, along with a small PVC drainage pipe next to the collection site. Not only was there drainage running into the river, the site was under a bridge, and contained other trash scattered throughout the area. The

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

The purpose of this lab was to identify unknown bacteria cultures using various differential tests, and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures were Gram stain, Catalase, Mannitol Salt Agar (MSA), Blood Agar, Novobiocin, Coagulase, and DNAse (Alachi, 2007).

Because the subjects had to inhale to smell of the peppermint oil the amount of peppermint oil inhaled from the surgical masks could not be measured so every subject that took part in the test most likely inhaled  different amount of the oil so the results would be different for each person making the overall experiment invalid. There was only on task to measure reaction time but it would have improved to validity of the experiment if there was more methods to test reaction time. Also with inhalation the smell of a substance will stay with one person for longer then it will for another so this method of inhaling the peppermint oil can’t be conclusive.

The purpose of experiment four was to synthetically prepare a sample of salicylic acid from methyl salicylate, also known as wintergreen oil. The salicylic acid formed is to be compared to salicylic acid synthesized from benzene and determine whether or not the two acids differ. This experiment occurs through organic synthesis, meaning in order to create the desired product, the starting material must be chemically modified.

Our data will be collected by how much oil is collected in the hair, how much oil is left in the water, how much hair is coated in the oil, and how long it takes for the oil to be “absorbed”. Our measurements will be taken before and after the experiment to way the hair, and how much oil to water ratio. The tools that we are going to use is a scale and we are going to use stoichiometry. Our observation we are going to see it, and feel the oil on the hair. We will collect data everyday and the experiment will last 2 weeks. Are dependent variables is the amount of water we use and how wide and long it is. Are independent variable are the amount of oil used and how much hair we are going to use.

Mixture is always present in the experiments, knowing the content of a certain mixture that the researchers will going to use in the experiment will help them to avoid accidents and it may increase their level of safety as well as the precision and accuracy data that they will gather. However, having unknown mixture in experiment may decrease their level of safety and sometimes it may lead to errors and mistakes. Though, human errors are quite inevitable.

Since this experiment was exothermic, if solutions were added to the substance, the overall reaction could be altered. Adding the acetyl chloride too fast, would create excessive foaming of the solution, therefore speeding up the reaction and sometimes changing the color of the reaction product. This could result in inaccurate results. It would be ideal to set up a calibrated dropper, although this would require the rubber stopper to be off, thus letting air out/in. Another source of error is if the product was not left of blowing air for long enough, the correct weight would not have been recorded and thus the percent yield would be incorrectly determined. Another source of error could be the addition of the incorrect amount of anhydrous sodium sulfate. Adding too much or too little with both have implication to the outcome of the reaction. Too much will take out more molecules than just water and too little won’t absorb all the water molecules present. This experimental procedure was a good procedure to carry out this reaction. Instances of error have little to do with the design of the experiment and more or less, the way it’s carried

Lorenzo's oil is the name of the film I am reviewing, this movie included an d variety of characters. With the main characters being Lorenzo the kid that gets ALD, the mother melissa and the father augusto odone. There were also a couple of other important characters such as the doctors/nurses. The movie took place in the 90’s era in the united states. The movie’s release date was December 30, 1992.

The composition of volatile fractions of Agarwood oil will be determined using gas chromatography spectrometry (GC-MS). GC-MS Analysis will be carried out using an Agilent-technology chromatograph with fused silica capillary column (30m x 0.32 mm i.d. x 0.25 pm). Oven temperature will be performed at 60° C to 210° C at 3°/min; 210° C to 240° C at 20 °/min and hold for 8.5 min. The injector temperature will be at 280° C while the detector temperature will be at 290° C. The carrier gas is N2 (1 ml/min); split ratio of 1:50. GC-MS analysis will be carried out at 70 eV ionization energy, equipped with a HP-5 MS capillary column (phenyl methyl siloxane, 30m x 0.25 mm i.d* 25pm) with He as the carrier gas and split ratio 1:50.

OBJECTIVE: The objective of this experiment is to find the density of metals through taking physical measurements and graphing data using the Vernier LoggerPro software. This was achieved through finding the mass and the volume of multiple samples of two types of metals and finding the average density of the samples of each type of metal, keeping record of the mass and volume of each sample, and inputting the data into the LoggerPro program.

In the investigation we were asked to find the individuality mole ratio for the formation of CO2 after the reaction of sodium bicarbonate and acetic acid. To determine the mole ratio between sodium bicarbonate and acetic acid is to look at the balanced chemical equation for the coefficients in front of the substances you are interested in. The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation ensures when the number of the different atoms of elements in the reactants side is equal to that of the products side. A chemical reaction is when two compounds, react together and forms two different products. Assuming how much reactant is required then finding out the product that

In week one we performed a qualitative solubility test of our fats and oils, synthesized our soaps and detergents, and performed a solubility test and lathering test for the soaps and detergents. We wanted to test the solubility of our starting materials of the soap making process to understand the properties of the materials. In our initial solubility test of the starting materials, we found that most of the materials were insoluble. As you can see in Table 2.0, olive oil and vegetable oil were only soluble in toluene and the shortening and lard were only partially soluble in acetone. In order to understand the solubility of the soaps and detergents, after our synthesis and filtration, we performed a qualitative solubility test with each of

The purpose of this lab was to create soaps and detergents and test their cleaning ability. We created four different soaps and two detergents using different starting materials composed of oils and fats for the soaps and lauryl alcohol and sulfuric acid for the detergents. Soaps are created by a process called saponification, which is the formation of a salt by combing an acid and a base.1 Soap and detergent are effective cleaning agents because they have hydrophilic and hydrophobic ends.1 The hydrophobic ends interact with the dirt and oil while the hydrophilic ends interact with the water molecules effectively washing the dirt and oil away.2 While soaps and detergents are very similar in their cleaning ability, they have a major difference being that soaps are made from natural products and detergents are made from synthetic materials.3 In order to make the soaps, we used four different starting materials including lard, shortening, olive oil, and vegetable oil.
