Name CHE 173 Sec # January 25‚ 2005 Experiment 36: Determination of the Structure of a Natural Product in Anise Oil Purpose: The purpose of this experiment is to isolate the major component of anise oil and determine its identity and structure using melting point determination and IR spectroscopy. Introduction: The major component of anise oil has the chemical formula C10H12O. This compound is said to be hydrogen deficient‚ meaning that it contains less hydrogen atoms than would be needed for

your own Divisional Chief Executive make a careful and well prepared and argued case for such a strategic move an imperative. Consideration of alternative market entry strategies EPP has achieved significant growth to date through a combination of product and market development. Importantly‚ this has not led to diversification away from the core business which is important bearing in mind the 1990s experience of the Group Chairman and Chief Executive to previous geographic diversification.

How do ionic compounds form? How do electrons change the shape of a molecule? These are just a couple of the questions that this paper will answer. How do ionic compounds form? Ionic compounds are formed by positive and negative ions. An ionic bond means that there are valence electrons being shared between the two molecules. This can cause the molecule to become negative or positively charged. An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal and the

Tittle: Determination of moisture Objectives: 1. To determine the moisture content of selected food samples using drying oven method 2. To determine the moisture content of selected food samples using moisture analyzer. Introduction: Moisture content is one of the most commonly measured properties of food materials. The choice of an analytical procedure for a particular application depends on the nature of the food being analyzed and the reason the information is needed. In this experiment

2. I noticed that all of the ionic compounds are soluble in water. This is due to the fact that water molecules are polar. Meaning that they have dipole bonds‚ which have a slightly positive and slightly negative end due to electronegativity differences between atoms. When ionic bonds are placed in water‚ they dissociate into their ions (positive and negative) due to the process of dissociation. These ions are then attracted to different dipoles present in the water molecule‚ in other words the negative

increase in intracellular calcium led to skeletal contractions. However it was not until the early 1960s when the way calcium ions were stored in cells became clearer thanks to work from Ebashi and Lipmann. (Burgoyne and Petersen‚ 1997). Calcium signalling determines whether or not a cell is activated. It is determined by calcium-ON and calcium-OFF mechanisms. Calcium-ON is responsible for pouring Ca2+ into the cytoplasm‚ from both internal and external sources. The calcium-OFF mechanism however removes

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is‚ we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into or (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)

EFFECTS OF WATER SOLUTIONS IN PLANT GROWTH CHAPTER I Introduction Plants are affected by different substances that come into contact with them. These effects may be good or bad. There are certain substances such as fertilizers‚ which have a positive effect on the growth of certain plants‚ more specifically pechay (Brassica rapa variety chinensis). Pechay is commonly used in cooking in Filipino households. It requires little attention as it is a very hardy plant. It is rich in vitamins A‚
