Empirical Formula of a Compound * Purpose: To determine the empirical formula of Magnesium Chloride. * Data 1. Mass of evaporating dish = 45.08g 2. Mass of evaporating dish and Magnesium = 45.17g 3. Mass of Magnesium: { 2 } – { 1 } = 0.09 4. Mass of evaporating dish and Magnesium Chloride First weighing = 45.48g (After heating and cooling) second weighing = 45.49g 5. Mass of Magnesium Chloride: { 4} – { 1 } = 0.41g

Bearing the Smoke It’s wonderful to see how two very distinct individuals‚ meaning different culture‚ have so much passion for Africa. Taking their time to plan‚ travel and even learn 50 words of that tribe/group before they entered. Ten years of documenting‚ traveling and living with these groups must have become their only priority. I find grace and true selflessness in how Beckwith and Fisher would help these villages with the concept as stated in the article: “And our goal wasn’t to give

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

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

bone has been displaced from the point in where it should be. There are different types of fractures with the most common being hairline and compound. Hairline fractures are where there is a very fine line between the segments of the bone that appears when x- rayed. The bone segments will remain in alignment and the fracture may not go fully through. Compound fractures are also known as open fractures so if the skin has been pierced the outside air must be able to get to the fracture site without

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
