Introduction What is organic food? • (1) Organic food is food which has been produced to standards designed to keep the production more ’natural’. Fewer‚ if any‚ chemicals are used and most pesticides are banned - when they are used they are very carefully controlled. • (2)Organic food costs more then non-Organic food. This is not always the case but on average organic farmers generally charge more for their produce because: o Many organic farming practices take a bit longer and produce lower

The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin‚ and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all

9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation

Biology Lab Report Research Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic

Pepto Bismol. That’s why the b in “Bismol” is capitalized‚ because of the bismuth use. Bismuth is also used in makeup products and lead bullet replacement. Bismuth is known to be toxic‚ but only if you have too much at a time. Bismuth has no dangerous effect on the environment. In the last 20 years the demand for bismuth has risen due to its effective use as a substitute for lead in bullets. The cost for bismuth is $11 per 100 grams. Sales are open to everyone from the military to and average highschool
