Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

The Compound Light Microscope Commonly binocular (two eyepieces)‚ the compound light microscope‚ combines the power of lenses and light to enlarge the subject being viewed. Typically‚ the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses‚ which can be rotated into the field of view‚ produce higher magnification to a maximum of around 1000X generally. The compound light microscope is popular among botanists for studying plant cells‚ in

properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness‚ safety and potential yield of the compound. So to be more specific about

HYPOXIA Introduction Hypoxia is simply a lack of oxygen at the tissue level of the body due to a decreased partial pressure of oxygen in the inspired air. Hypoxia is serious‚ because it may lead to death. Diseases of the blood‚ the heart and circulation‚ and the lungs may all produce some form of hypoxia. There are four types of hypoxia: (1) the hypoxic type‚ in which the oxygen pressure in the blood going to the tissues is too low to saturate the haemoglobin; (2) the anaemic type‚ in which

Bearing the Smoke It’s wonderful to see how two very distinct individuals‚ meaning different culture‚ have so much passion for Africa. Taking their time to plan‚ travel and even learn 50 words of that tribe/group before they entered. Ten years of documenting‚ traveling and living with these groups must have become their only priority. I find grace and true selflessness in how Beckwith and Fisher would help these villages with the concept as stated in the article: “And our goal wasn’t to give
