BIOFERTILIZER: The pathophysiology of the Tuberculin reaction is explained thus: M. Tuberculi are engulfed by macrophages after being identified as foreign‚ but due to a self- preserving mechanism peculiar to TB it is able to block the fusion of the phagosome within which it is existing with the lysosome which would destroy it. So it can continue existing and replicating within the immune cell designed to destroy it. After several weeks‚ the immune system somehow [ mechanism as yet unexplained]

Topic 5 – Bonding and Structure Revision Notes 1) Introduction • Atoms form bonds to get a full outer shell of electrons • There are three types of bonding: ionic‚ covalent and metallic • The structures produced by forming bonds are either giant or simple • The possible combinations of structure and bonding are giant ionic‚ simple covalent‚ giant covalent and giant metallic • Simple covalent is sometimes called simple molecular • Giant covalent is sometimes called giant

1. What is the ideal solvent for crystallization of a particular compound? What is the primary consideration in choosing a solvent for crystallizing a compound? volatile in order to be easily removed from the purified crystals. In selecting a solvent consider that like likes like. Polar compounds dissolve polar compounds and non-polar compounds dissolve non-polar compounds. Solvent will dissolve a large amount of the impure compound at temperatures near the boiling point of the solvent the compound

The Cyclohexanol Cycle and Nylon Synthesis Samantha Stuckey CHE 233L Section 302 Department of Chemistry‚ DePaul University‚ 1110 W. Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination
