is green‚ when an alcohol is oxidized by the reagent. A change in color of the reagent from orange to green represents a positive test. Primary alcohols are oxidized by the reagent to carboxylic aicds; secondary alcohols are oxidized to ketones. Tertiary alcohols are not oxidized at all by the reagent. Hence‚ this reaction can be used to distinguish tertiary alcohols form primary and secondary alcohols. Procedures: 1. Place ethanol‚ isopropyl alcohol and tert-butyl alcohol in three different

This essay will review both the positive social effects and negative social and physical effects of alcohol. The debate over alcohol consumption in communities around the world has existed as long as there has been alcohol to drink. Alcohol has improved social functions; community economics through tourism and business and in moderation can enhance many situations in society. Alcohol has been one of the main problems of today’s generation. By contrast if over indulged and abused the same product

Introduction In the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them) because they

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

Bacteria Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. Another group of microbes‚ the archaea‚ meet these criteria but are very different from the bacteria in other ways. In fact‚ there is considerable evidence that you are more closely related to the archaea than they are to the bacteria! Bacteria are living things that are neither plants nor animals‚ but belong to a group

Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

and injecting them with a larger amount of ethanol. The rats that stayed in the same location remained relatively healthy‚ while nearly two-thirds of the rats in the new location died of alcohol poisoning. A similar experiment involving rats and morphine showed that the body can overcompensate for the expected effects of a drug when presented with a smaller dose. Rats were given relatively large doses of morphine for several days‚ and when given drastically smaller doses‚ their bodies displayed symptoms

Alcohol Poisoning Not many people know about or what alcohol poisoning is. You can get it from excessive drink which will result in not only harming yourself‚ but others around you too. Some people find that drinking is a joke or think it’s funny‚ but it’s not. Every time you drink alcohol‚ your liver has to filter out the poisonous alcohol from your blood. Alcohol is absorbed quickly into your body (much quicker than food)‚ but the body can only process around one unit of alcohol each hour. If

1.A) Two main forms of cells exist: eukaryotic cells and prokaryotic cells. Prokaryotic cells are smaller and do not have membrane-bound nucleus or membrane- bound organelles‚ but do have: plasma membrane‚ cytosol and cytoplasm‚ and ribosomes. Prokaryotes contain much less DNA than eukaryotes and have circular chromosomes. Eukaryotic cells have information processing organelles‚ such as the nucleus which houses most of the cell’s DNA‚ and ribosomes which use information from DNA to produce proteins
