Single deplacement occurs between an element and a compound. During single deplacement reactions one metal replaces another metal in a compound. The general formula for this is: Ax=Y Ay+X. An example of a single deplacement reaction is Copper chloride+Aluminum chloride--+aluminum

Usually an aqueous and organic phase are used. During extraction the desired compound moves one phase and leaves the unwanted substance behind. Extraction normally has to be done a few times to leave all of the impurities behind. TLC plating can be used to

Analysis of Alum AlK(SO4 )2 . 12H2O AP Chemistry Lab # 5 INTRODUCTION Every compound has a unique set of chemical and physical properties. To identify a compound with certainty‚ experiments have to be conducted in order to verify these properties. Such kind of analysis is usually performed when a compound is synthesized‚ and whether the compound is indeed the compound desired needs to be ascertained. The main purpose of the experiment is to analyze alum‚ AlK( SO4

ABSTRACT Determining the melting point of a solid organic compound is the easiest way to identify the compound and determine its purity at the same time. For actual samples of compounds‚ the melting will occur over a range of temperatures making the melting points into a melting “range”. The difference between the temperature at which the sample begins to melt and the temperature at which it finishes melting‚ or the magnitude of the melting range‚ is a very important criteria of determining the

ten thousand discovered compounds actually becomes an approved drug for sale. Much expense is incurred in the early phases of development of compounds that will not become approved drugs. In addition‚ it takes about 7 to 10 years and an average cost of 500 million dollars to develop each new drug. This money is spent before the FDA approves the drug‚ and if the drug is not approved‚ the company loses the money. These expenses must be covered by the revenue from compounds that successfully become

Compound Fractures A compound fracture‚ also known as open fracture‚ is a fracture of the bone wherein the affected bone penetrates out from the skin and there is laceration of the surrounding soft tissue. A broken bone refers to a fracture‚ in medical terminology. Bone fractures are quite common‚ with people experiencing at least two in their lifetime‚ on an average (Eisenberg‚ 2007). A fracture occurs when the affected bone is subject to a physical force that is stronger than it can sustain. Age
