Mechanisms of Acetaminophen-lnduced Liver Necrosis By Jack A. Hinson‚ Dean W. Roberts‚ and Laura P. James Acetaminophen (paracetamol‚ N-acetyl-p-aminophenol; APAP) is widely used as analgesic and antipyretic drug. At therapeutic doses‚ acetaminophen is safe to be used. Acetaminophen other than aspirin and ibuprofen has only weak anti-inflammatory properties. At higher doses‚ acetaminophen produces a centrilobular hepatic necrosis that can be fatal.

Some common antiseptics[edit] A bottle of ethanol (95%) - an antiseptic Alcohols Most commonly used are ethanol (60–90%)‚ 1-propanol (60–70%) and 2-propanol/isopropanol (70–80%) or mixtures of these alcohols. They are commonly referred to as "surgical alcohol". Used to disinfect the skin before injections are given‚ often along with iodine (tincture of iodine) or some cationic surfactants (benzalkonium chloride 0.05–0.5%‚ chlorhexidine 0.2–4.0% or octenidine dihydrochloride 0.1–2.0%).

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

RADICAL HALOGENATION AND GAS CHROMATOGRAPHY Abstract In radical halogenations lab 1-chlorobutane and 5% sodium hypochlorite solution was mixed in a vial and put through tests to give a product that can then be analyzed using gas chromatography. This experiment was performed to show how a radical hydrogenation reaction works with alkanes. Four isomers were attained and then relative reactivity rate was calculated. 1‚1-dichlorobutane had 2.5% per Hydrogen; 1‚2-dichlorobutane had 10%; 1‚3-dichlorobutane

8% or more acetic acid to descale the appliance‚ as this may cause damage. http://www.diynot.com/forums/viewtopic.php?t=30088#axzz2Bph0xR9a Citric acid will do a better job than the acetic acid in vinegar. That’s because calcium citrate dissolves in water whereas calcium acetate forms an insoluble layer between the scale and the vinegar. You can buy citric acid crystals from home brew shops. A teaspoon of acid in a kettle of water is a good start and you can speed things up enormously by boiling

Chemists are able to make many things once they understand the periodic table. For example‚ if a person wants to clean in his/her bathroom‚ they would probably use bleach‚ which is a sodium hypochlorite liquid and calcium hypochlorite as a solid. When a person uses soap to take a bath‚ they are using an element from the periodic table as well. The elements on the periodic table are widely used all over the world. Out of all the elements on the periodic table
