What is the mass of the chemical in grams in the above procedure? When using the weighing paper for this procedure the mass of the given chemical is 4.74g 6. Write a complete and accurate procedure for weighing a chemical by difference in a volumetric flask. When using a top loading balance there are two ways to complete a weighing procedure. The most accurate way to complete this procedure is by weighing the chemical by difference.
"Gatorade focus has always been fluid replacement" (Theodore). Gatorade is specifically designed to refuel the body quicker than water or any sports drink for that matter. Gatorade Company spends most of its time making sure the consumer will not overheat. "The company maintains that its formula of carbohydrates (sucrose, glucose and fructose) and electrolytes (potassium and sodium) is the optimal mixture for stimulating fluid absorption, helping the body maintain fluid balance, providing energy to working muscles and enhancing athletic performance" (Kays and Phillips). All the ingredients in Gatorade are exactly made to make sure you stay hydrated.
Protects the bacteria from phagocytosis allowing the bacteria to stay in the body 6. pure culture 7. It is differential based on hemolysis of the agar. Hemolysis can be wide-narrow band beta, alpha, gamma, or none. 8. candle jar in microbiology is used for anaerobiosis in which a lit candle is placed in an air tight jar and if it went out, it would be because it used up all the available oxygen. 9. any streptococcus capable of hemolyzing erythrocytes, classified as α-hemolytic type, producing a zone of greenish discoloration much smaller than the clear zone produced by
(d) What evidence suggests that nitrate compounds are soluble in water? (e) Write the chemical formula for each precipitate that formed. Apply and Extend (f) Write a balanced chemical equation for each precipitation reaction that occurred. (g) Why is it necessary to use distilled water to prepare the solutions used in this investigation? (h) "Hard" water contains a high concentration of calcium ions.
We could also determine the efficiency of our alum at clearing the beaker of muddy water. Introduction: The purpose of the experiment is to see the chemical process of aluminium foil, potassium hydroxide (KOH), and sulphuric acid (H2SO4) to have alum (KAl(SO4)2 12H2O) crystallize as a product. The compound is used widely for the treatment of wastewater in plants, water purification, the preparation of some food products, and dyeing of fabrics. The method used during this experiment was suction filtration; it uses a vacuum caused by water to filter out any impurities and also to collect any product that is created during the experiment. The equipment used during this experiment was a Buchner funnel that is attached to a filter flask with the use of a rubber ring to ensure that suction can occur.
Because this reaction is reversible, a fractional distillation is necessary to produce cyclohexene, water, and some impurities and a simple distillation is followed to further purify the product. [pic] (Fig. 1- Cyclohexanol dehydrated by sulfuric acid to produce cyclohexene) Procedure: 1. Mix five mL of Cyclohexanol and 2.5 mL of 9M sulfuric acid in a 25 mL flask. 2.
Steam Distillation: The isolation of limonene 1. Purpose The purpose of the experiment is to be familiar with the use of steam distillation, to learn how to extract an organic solvent and remove a volatile liquid by a rotary evaporator, and to determine the purity of the limonene. Steam distillation was used because it is a special type of distillation especially for temperature sensitive materials. Dichloromethane was used to extract the aqueous mixture. Magnesium sulfate was used to absorb water and simple filtration was used to remove magnesium sulfate.
The Fluid Milk Manufacturing handles one or more activates which include the processing of milk products, such as pasteurized milk, cream, and sour cream. Fluid Milk is an industry term for milk processed for beverage use. Fluid Milk is pasteurized using a high temperature short time continuous process of at least 161F for 15 seconds. These conditions provide fresh tasting milk that meets the requirements for consumer safety. Fluid Milk is often fortified with Vitamin A & D. The package label must declare when milk is fortified.
Isolation of Caffeine Introduction Caffeine is a stimulant found in the cacao plant that is used, today to increase alertness when taken in moderate doses. In this lab, we extracted caffeine from 2 NoDoz tablets, which contains 45% caffeine. We accomplished this task by performing a hot gravity filtration to separate the insoluble binder from the caffeine, a liquid extraction to separate the organic caffeine-containing layer from the aqueous layer, a gravity filtration to filter off the hydrated salts, a steam bath evaporation to evaporate out the organic solvent, and a recrystallization to obtain dry caffeine crystals. The ultimate goal of this lab was to acquire the same amount of caffeine as listed on the NoDoz tablets. Materials and Methods Materials The compounds used in this lab are listed in the table below: Procedure We boiled 2 NoDoz tablets in grinded form with 60 mL of water in a 100 mL beaker and allowed it to cool to room temperature after it had been sitting on the hot plate for 5-10 minutes.
