in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its expected propensity observed‚ this will cause the temperature range to widen. Using this hypothesis‚ mixed melting point technique could determine if the unknown compound added to the mixture causes a temperature depression‚ if not‚ the unknown is likely to be the same as your starting compound. Results: Melting

Teachers’ Notes Written by Bronwyn Owen CAMEL RIDER By Prue Mason Overview For Adam‚ living with his pilot father and family in an expatriate compound in Abudai in the Arabian Gulf‚ life could not be easier. But when war breaks out‚ Adam finds himself alone and attempting to find his way back to the abandoned compound to save his dog‚ Tara‚ who has been left in the mad rush to escape across the boarder. We also meet Walid‚ living a miserable life as a camel rider in a camp on the outskirts

MATHEMATICS OF INVESTMENT Simple Interest If you borrow a car from a car rental company or if you live in someone else’s house or apartment‚ you have to pay rent. Like paying rent for the use of a car or a house‚ you also have to pay rent for the money you borrowed. This is called interest. People like Marco earn by charging interest on loans. Banks earn most of their income from the interest that people pay for the amounts they borrow. How much interest one has to pay depends on three factors:

substances: an element and a compound. Element: A substance that cannot be broken down by chemical means. An element is a pure substance because it is made up of one type of atom it also cannot be broken down further into another substance. (This deems it pure) Compound: A substance that is made up of 2 or more elements‚ it is still considered a pure substance because while the elements bond so do the atoms. Therefore there is only one type of atom in the compound. Impure substance- Mixture:

However‚ it should be noted that although the reduction of particle size increases the specific surface area and the dissolution rate‚ it does not affect solubility. The rate of dissolution may also be altered by choosing a suitable polymorph of a compound. Different polymorphs exhibit different solubility and dissolution rate

EXPERIMENTATION - 1953 Urey and Miller collaborate effectively to design an experiment/model to simulate conditions on early Earth and test the hypothesis that life molecules could originate on Earth 4. RESULTS - Urey and Miller results confirm that simple organic compounds (amino acids) could form from the conditions on early Earth 5. ASSESS EXPERIMENTAL DESIGN

Melting Points Elizabeth McGrail Organic Chemistry I 25 January 2013 ABSTRACT The objectives of this lab are‚ as follows; to understand what occurs at the molecular level when a substance melts; to understand the primary purpose of melting point data; to demonstrate the technique for obtaining the melting point of an organic substance; and to explain the effect of impurities on the melting point of a substance. Through the experimentation of three substances‚ tetracosane‚ 1-tetradecanol and

This week concepts were of function problems which may include exponentials and logarithms within the functions. With these types of function we can find out information for breaking-even and profit analysis‚ compound interest‚ continuous compound interest and doubling time for an investment. Out of these concepts from this week lesson plan‚ currently understanding and using doubling time for an investment would be the most important. In this world we live in today‚ the economy has taken a huge
