Introduction Crude fat is the term used to refer to the crude mixture of fat-soluble material present in a sample. Crude fat also known as the ether extract or the free lipid content the traditional measure of fat in food products. The lipid materials may include triglycerides‚ diglycerides‚ monoglycerides‚ phospholipids‚ steroids‚ free fatty acids‚ fat soluble vitamins‚ carotene pigments‚ chlorophylls‚ etc. The common approach for total crude fat determination is based on the solubility of lipids

There were a numerous amount of observations and patterns in the data throughout the candle lab. The hypothesis was if the amount of candles inside the jar increases by an increment of one‚ then the weight of water in the jar will increase as well. The hypothesis was proven to be true‚ since for every candle added there was about 33 grams of water more. Every time the jar was placed over the candles‚ there would always be bubbles around the rim‚ also as more candles were used‚ the jar became cloudier

1. Describe results – clearly state the trend from the graphs‚ citing specific values. Link this to the results you obtained from conducting the experiment. The results gathered clearly state that our results which were 71oC and 90oC are quite close to the classes average set of results by about 2‚ but‚ when graphing the alkalise by the boiling and melting point they both follow the same slope‚ it continues to rise just like the results gathered in the example do. 2. Which of the 2 unknown substances

The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

Synthesis of Phenacetin from para-Acetamidophenol Aims: To determine how phenacetin from acetamidophenol (known as paracetamol) is synthesized using Sodium Ethoxide Iodine‚ which is the Williamson Ether synthesis. Experimental: Sodium metal was patted dry to remove any oil and was cat into small pieces. A dry 100cm3 round bottom flask was placed on a cork ring‚ on a balance and tarred sodium metal (0.6g) was placed into the flask. The flask was then attached to the dry reflux condenser

CHAPTER III METHODOLOGY Research Design In this study‚ an experimental design will be used to test the pesticidal effect of betel nut kernel extract on leaf miner larvae (L. trifolii) The researchers of this study used standard laboratory procedures concerning to the detection of the pesticidal activity of betel nut kernel extract. This study used (4) treatments of betel nut kernel extract‚ which were as follows: 1. T1 –betel nut kernel decoction 2. T2– crude kernel

How do you keep carbon dioxide from escaping a carbonated drink when the drink’s container has been opened? When you open a carbonated beverage’s container‚ such as a soda can or bottle‚ you may hear a hissing sound from the opening as you do so. That is the sound of the carbon dioxide gas escaping from the sealed container through the new opening. When this happens‚ the process of the beverage losing its so-called "fizz" has already begun. However‚ there are several solutions to this issue. This

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

For this experiment‚ we started off by taking tubes numbered 1-4 and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and

1. Ventilate the work area well‚ cover the work space with newspaper‚ and put on gloves and goggles. Be sure pets and kids are not running underfoot as begin this project. 2. Start by measuring the oils and placing them into the crock pot. Remember: For this recipe measuring all ingredients by weight‚ not by volume. 3. Turn the crock pot on high and melt all the oils. Better to use a smaller crock pot to cook the ingredients down and then move to a larger one once start adding the liquids. 4. Place
