Many of these food advertisements that children are being exposed to are products that are of low nutritional value. More than two hundred school districts have signed agreements with food companies nationwide. Within these districts‚ there are more than forty-five hundred Pizza Hut chains and more than three thousand Taco Bell chains

The Effect of Different Isotopes on Atomic Mass Introduction: An isotope is a variation of an atom that already exists. An isotope is different from an atom because of the number of neutrons in its nucleus. Finding the amount of neutrons in an atom can be calculated by subtracting the atomic number of a specific atom from its atomic mass. When looking at the periodic table‚ the atomic mass in the top left corner of every box is a decimal. The mass is in decimal format because the number listed

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof

Introduction And what is known about the sustainability of current groundwater‚ it is that it will not last. Ponce (2006) states” The unsustainable use of groundwater stands to significantly impact a host of hydrological‚ ecological and other natural resources and services‚ including freshwater bodies‚ and aquatic‚ riparian‚ transitional‚ and ecosystems.” All life on planet earth depends on clean freshwater to survive and It is very important that this natural resource is taken care of properly

Experiment 3: Soil pH measurement Introduction Aims The aims of the experiment were to determine the pH of a variety of soils which included sedentary‚ 3:2‚ sand‚ organic matter with the means of a pH meter at various soil water ratios and with or without calcium chloride. Method and Materials Samples of sedentary soil‚ 3:2 soil‚ sand‚ organic matter and compost‚ 100ml vials(x12)‚ bottle of distilled water‚ analytical balance‚ pH meter‚ 2 buffer solution of known pH‚ 0.25M calcium chloride

you had to find out if the food you picked contained starch‚sugar‚lipids and protein.The food item that was chosen to decipher was a Big Mac and you chose what from the burger you wanted to test to see what it was made of‚ example like the bun of the burger. When testing you would have one test tube of water with food and the other test tube with the solution needed and food.The reason for the test tube with the water is because it was the indicator. If the product of food contained the macromolecule

Monstar Lab PH : Testing as A Service Software testing is essential to the software development nowadays and will continue to be in demand as time goes by. Apps are getting more and more critical to the human lives day by day and the speed to market is getting faster more than ever and yet it’s a must for software companies to provide stable and satisfying applications. Throw in the costing constraints and evolving requirements in the mix‚ and you’ll now position yourself where software development

of one or more compounds‚ is injected into the column and is carried through the stationary phase by atmospheric air‚ which acts as the mobile phase. The nonpolar coating of the stationary phase most strongly retains solutes of the same polarity. Organic compounds flowing out of the chromatography column are then detected by a chemical sensor that produces electrical responses proportional to the concentration of the compounds. The presence of such a chemical at the detector is seen as a peak on a

Redox Titration Lab ABSTRACT: In this lab‚ 0.010 M purple-colored potassium permanganate solution was standardized by redox titration with iron (II) ammonium sulfate hexahydrate (FAS). The average mass of the three flasks of FAS was 0.483 grams. Once the concentration of the standard solution of KMnO4 (aq) was determined‚ it was used to determine the concentration of Fe2+ in iron pills. On average‚ there was 0.01813 L of solution used. With this information and the balanced net-ionic equation
