Quaternary ammonium compounds‚ QAC‚ are ingredients found in household products such as fabric softeners‚ detergents‚ disinfectants‚ and hair products that consist of dialkyldimethylammonium compounds (DADMC)‚ benzylalkyldimethylammonium compounds (BAC) and alkyltrimethylammonium compounds (ATMAC) (Li and Brownawell 2010). While trying to find the reason why these rivers keep getting contaminated‚ Brownawell found out that the wastewater areas found in surficial sediments around the Hudson River

Yentl Smith BIOL 3810-504 Compound Action Potentials Date Performed: 15FEB2011 Date Due: 01MAR2011 Introduction Neurons are the cells that receive and transmit electrical signals (University of North Texas‚ 2010). The ability of the neuron to conduct these impulses is because of an electrochemical voltage across the plasma membrane of that neuron. An action potential is an all or nothing response to a stimulus along a single axon. A compound action potential is a graded response that

The Branch Davidian Compound was established as living-worship center for the members of the sect to reside. The residents of the compound lived‚ worked‚ learned‚ and worshipped in the isolated community. Because of the nature of the isolation and basis of the belief system of the Branch Davidian church created a unique way of life for the residents. Life in the compound was mostly dictated by David Koresh because he was a self-proclaimed messiah (equip.org) in which the members followed. Because

Identifying Organic Compounds 2. Purpose/Problem: I am doing this experiment to find out what kind of organic compounds are in test tubes A‚ B‚ C and D. I am curious to know if substance D was the lipid because it seemed thin and had a slightly yellow tint of color to it. 3. Research: In my research I was informed about facts and appearances of lipids. First of all lipids are non-polar compounds‚ thus they won’t dissolve in water. This is also known as being hydrophobic. They are made with one

Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

Identifying Ionic Compounds Written by Ashleigh Lara. In our experiment we were given 5 different cations who’s mixture of anions ranged from five to three different solutions. At every single station we were given the following materials a spot plate‚ a dropper‚ and the chemicals used to mix with our main substance. Each substance received 3 drops of the different chemicals which were able to give us an observation of what the compound was made into. Many of our experiments color‚ texture and solubility

Analysis of Oxygen Bearing Organic Compounds James Matthew Jocson*‚ Gianvittorio Lanta‚ Chiqui Ann Llamado‚ Jeron Manaig College of Science Department of Biology University of Santo Tomas‚ Manila‚ Philippines Abstract Five oxygen-bearing organic compounds were given namely Methanol‚ 2-propanol‚ tert - butanol‚ formalin‚ and acetone. Different tests were done to each sample to differentiate their characteristics. These test were Dichromate test‚ Tollens Test‚ DNPH test‚ Iodoform Test‚ and Lucas
