Compound Light Microscope The familiar compound light microscope is a series of lenses (hence "compound") that focus visible light in such a way as to produce a magnified image. A single lens‚ often called a magnifying glass‚ cannot generally magnify images as much as a series of lenses although Antony van Leeuwenhoek‚ the first microbiologist‚ used a simple‚ albeit exquisitely crafted‚ lens to discover single-celled "animalcules‚" as he called them. Advantages: Basic compound light microscopes

1. Who benefits from the government policies to (a) promote production of ethanol and (b) place tariff barriers on imports of sugar cane? Who suffers as a result of these policies? ANS: Benefiters in promoting production of ethanol: -Corn producers. They get subsidies from the government and get a free way of marketing from the government. The government promotes consumption of ethanol‚ ethanol is produced out of corn‚ so indirect marketing for corn farmers that will get more demand out of policies

Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

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

1. Hawley-Smoot Tariff a. The Hawley-Smoot Tariff was signed into law by president Herbert Hoover and passed in 1930. It raised the United States tariffs to unreasonably high levels. Although the tariff made life hard‚ it did not cause the Great Depression. The Hawley-smoot Tariff became a symbol of the “beggar-thy-neighbor" policies‚ which were policies designed to improve a person’s own lot at the expense of others. These policies contributed to the decline of international trade. The original

Compound 50‚ like its known analogue 3‚ involves an α‚β-unsaturated ketone‚ an acid-sensitive reactant‚ which prevents its direct synthesis in presence of protic solvents by refluxing. Despite of this characteristic‚ 50 was formed smoothly in 5 minutes by grinding chemistry‚ solely as E-isomer‚ without any evidence of decomposition after 1H and 13C MNR analysis. This synthetic approach provides easy access to such α‚β-unsaturated N-acylhydrazones‚ which are building blocks in the synthesis of nitrogen-containing
