computer ------------------------------------------------- Computational chemistry From Wikipedia‚ the free encyclopedia Computational chemistry is a branch of chemistry that uses principles of computer science to assist in solving chemical problems. It uses the results of theoretical chemistry‚ incorporated into efficient computer programs‚ to calculate the structures and properties of molecules and solids. Its necessity arises from the well-known fact that apart from relatively recent results

for nitropentamminecobalt(III) Chloride = 0.76 g(76 %) Introduction Linkage isomers may arise when one or more of the ligands can coordinate to the metal ion in more than one way. The first reported example of linkage isomerism had the formula [Co(NH3)5(NO2)]Cl2.1 This compound exists in two isomeric forms; one containing Co-NO2 linkage‚ the other the Co-ONO group.2 In this experiment‚ the synthesis of both of the isomers will be performed. The figure below illustrates the bonding in nitrito(on the

Professor Nieter Science Inquiry: Geoscience Introduction Astrobiology is the area of study dealing with alien life‚ the likelihood of finding it‚ where it might be found‚ how it evolved‚ its morphology‚ its culture‚ etc. It’s a huge field that overlaps all the sciences but especially the geosciences‚ evolutionary biology‚ chemistry and bio-chemistry and astronomy. In the following report I focus on astrobiology as it applies to geology‚ or what kinds of planets‚ stars and solar systems are the
