Lab 6: Organic Compound Analysis Isabella O’Toole CHY 116 Friday 1:15-4:00 Lab Conducted on 4-12-13 and 4-19-13 4-26-13 This lab was conducted in order to determine the chemical composition of an unknown organic acid. A known mass of acid was dissolved into 30mL of either water or methanol (depending on solubility) and titrated with standardized sodium hydroxide. Data from this allowed the molar

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

13.1 Compound Interest • Simple interest – interest is paid only on the principal • Compound interest – interest is paid on both principal and interest‚ compounded at regular intervals • Example: a $1000 principal paying 10% simple interest after 3 years pays .1 3 $1000 = $300 If interest is compounded annually‚ it pays .1 $1000 = $100 the first year‚ .1 $1100 = $110 the second year and .1 $1210 = $121 the third year totaling $100 + $110 + $121 = $331 interest 13.1 Compound Interest Period

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 General Agreement on Tariffs and Trade (GATT) 1947 functioned as a means of adjusting trade relationships between countries trying to improve their economies. Contracting parties to this agreement have been bound by it to treat other contracting parties on an equal and reciprocal basis as well as to curb protectionism. At the start of 1995‚ the GATT has been succeeded by the World Trade Organization (WTO) and has since been the most important development in international trade. However‚ it is
