Title: Freezing and Melting of Paradichlorobenzene Purpose: Melting‚ freezing‚ and boiling points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance

spectrophotometric method of assay. After storage of these cells at 4 C reproducible results in replicate tests were not obtained. Desiccation of the phenol-killed cells with ’acetone did not provide a satisfactory cell preparation. Such cells gave variable results and were difficult to resuspend properly. It was assumed ’that ’ acetone influenced the ’sensitivity of M. lysodeikticus by reason of its fat

Flavoring Agents made from Aldehydes and Ketones Peter Konn Mountain State University Chemistry 302 7/31/12 Abstract This paper looks to delve into the chemistry behind ketones and aldehydes as well as related compounds. The endeavor involved looking into the way their bonding influences how they react. It also considers the simple physical properties of these compounds including their reaction with other compounds‚ chemical structures and formulas. The paper also looked to

fraying nails are caused by the nail plate becoming dehydrated‚ resulting in them peeling and splitting. Dr. Nabet recommends using polish to avoid further dehydration and to protect the nail plate. An acetone-free polish remover is advised‚ as this is less drying than those that contain acetone. While those with dry hair may rejoice in avoiding frizzy hair during the colder months‚ they may be prone to static and flyaway hair instead. Dr. Nabet points out that the lack of moisture in the air causes
