Introduction In order to determine the content of calcium and magnesium in an unknown sample of limestone‚ the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry‚ emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured¹.The calcium concentration or ppm can be measured using the absorbance of the

Absorption Costing Absorption costing is a method of costing that assigns a small percentage of production and overheads costs to the price of each product that is going to be sold. It accounts for all costs‚ direct and indirect‚ fixed and variable. For example; if 1000 products are made and the total costs are £10000 then each product would cost £10 before making a profit (10000/1000=10). Variable costs are costs that can be controlled by management or a sales worker. Whereas fixed costs are

Introduction At any particular wavelength the absorption of light when visible light passes through a solution depends on two factors: * The length of the light path * The concentration of the colored path The connection of these two variables is known as the Beer-Lambert Law: Absorbance (A) = ε c l Where ε is the absorption coefficient C is the concentration of the compound And l is the length of light usually 1cm When I is constant‚ this proves a linear relationship between

Dissolution[edit] In the most common situation‚ a tablet is ingested and passes through the esophagus to the stomach. The rate of dissolution is a key target for controlling the duration of a drug’s effect‚ and as such‚ several dosage forms that contain the same active ingredient may be available‚ differing only in the rate of dissolution. If a drug is supplied in a form that is not readily dissolved‚ the drug may be released more gradually over time with a longer duration of action. Having a

Complex Carbohydrates PERSONAL SUMARY: There is a very real difference between simple and complex carbohydrates. Let’s look at them. Simple carbohydrates‚ found in rice‚ pasta‚ white potatoes‚ and some dairy products‚ contain sugars that are broken down quickly by your body. This will provide your body with a quick burst of energy‚ but if the carbohydrates are not used quickly‚ the sugar will turn to fat. That’s why low-carb diets cut them out. But those diets often lump all carbs together

Strategy Instruction for making hot tea The first step is to discuss our ‘strategy’ or process. At this time I activate prior knowledge. We have a group discussion about kitchen safety‚ what we have learned thus far and then we move into the purpose of learning and we talk about when and why people drink tea; as well we now have an opportunity to see which we prefer hot tea or iced tea. Then we move right into step 2; which is modeling the process for my students. I model each of the following

Carbohydrate Loading There are many threats to an athlete during physical endurance competition whether it is a marathon or the decathlon. The most common forms of these threats include hypoglycaemia‚ fatigue‚ and loss of morale (which is usually caused by hypoglycaemia and fatigue). There is one connection that can be made between these threats and that is that all are caused one way or another through the lack of carbohydrates (Peterson). The most common way to combat these threats

Carbon‚ Hydrogen and Oxygen. These three simple elements make up one of the most useful substances for many living organisms: Carbohydrates. Carbohydrates are used for numerous processes in organisms from acting in important roles of cellular recognition in the human body to storing chemical energy in plants in the form or starch. The roles of carbohydrates in the human body alone are numerous; providing energy for working muscles‚ providing energy for the regulation of blood glucose‚ preventing

Abstract Carbohydrates are the most abundant organic compounds in the plant world. They act as storehouses of chemical energy (glucose‚ starch‚ glycogen); are components of supportive structures in plants (cellulose)‚crustacean shells (chitin)‚ and connective tissues in animals (glucosaminoglycans); and are essential components of nucleic acids (D-ribose and 2-deoxy-D-ribose). Monosaccharides‚ oligosaccharides‚ and polysaccharides are theclassifications of carbohydrates. This experiment involves
