Cobalt(II) Oxygen adduct complex Inorganic 461 lab 2-29-2012 Abstract This experiment uses Co(salen) as a model compound illustrating the uptake of oxygen in hemoglobin. SalenH2 was prepared as the intermediate‚ and reacted with hydrated cobalt to prepare Co(salen). Using Co(salen) the oxygen up-take was tested. The synthesis of SalenH2 produced 0.65 g. The percent yield of salenH2 was 116% on the filter paper and 105% after transferring salenH2 to a vial. The melting point of salenH2‚ was

Moreover‚ throughout the story Emmett’s regret consumes him. One of his many regrets was that he never stopped the other Gendarmes‚ watching as horrors took place and did nothing. He was a bystander to bullying on a grand scale. The other gendarmes drowning in their misguided ways treated the lives of the Armenians as pointless‚ Emmett watched on. Emmett recalls a moment in his past‚ “And then comes the horseman‚ his face obscured‚ approaching pawing the ground nearby‚ directing his steed’s hoof

Mathematics is eyes‚ears‚heart‚lungs and above all the basic developing tonic of any human civilization.Maths develops‚Maths reforms and Maths benefits. If maths is removed then there will be no rational thinking.The logic will lose its sense and in the absence of all these vital components there will be no new inventions in the realm of science and business and all of a sudden there will be no difference human and animals.Without maths the whole world will go mad and economy will be badly affected

Thesis: There are more costs as a result of Charlie’s experiment It is clear that there are more cost that weighs out the benefits of Charlie’s experiment. To start with‚ everyone needs to have a friend to make life more enjoyful and to share their important parts of their lives. But‚ after the surgery people would look at Charlie as if he wasn’t human at all. He had no one to share his experience being smart. In the story it said‚“All the rest demanded that I be fired.

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

Is it fair to deceive humans in an unethical psychological experiment in order to receive new information? This is a question that I believe needs to be asked when one thinks of the Milgram experiment‚ a psychological study set up in the U.S in 1965. American psychologist Stanley Milgram held an experiment in order to see how severely ordinary human beings could knowingly cause harm to another human. This idea came about when he studied the holocaust in Germany in WWII‚ and then in the Nuremberg

Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this‚ new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”. Metallobiomolecules
