Determination of Water in a Hydrate DESIGN – Aspect 1: Defining the problem & selecting variables Research Question: What percentage of Copper Sulfate Hydrate is water? Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of

The Effects of Population Density and Noise Paper Psy/460 The Effects of Population Density and Noise Paper Introduction There are quite a few people who believe that territoriality‚ privacy‚ and personal space mean the same thing‚ but that is not the case. As noted in this paper‚ they are completely different things. The author of this paper will describe the concepts of territoriality‚ privacy‚ and personal space; examine how these concepts have become increasingly important as populations

Density Matters: The Effects of Urban Growth Boundaries on Florida Urban Densities Prepared by Submitted to ___ Executive Summary Urban growth boundaries (UGB) are a growth management tool adopted from early English land use traditions to categorize land use. UGB’s are boundaries that clearly delineate the limit of the urban density growth permitted and supported by the issuing municipality. Florida instituted the Growth Management Act in 1985‚ mandating local comprehensive

Experiment #6: Colorimetric Determination of pH Almira‚ Faerie Carleen Lucile L. Gallardo‚ Charlotte O. Group #6‚ Chemistry 18.1‚ MHEG1‚ Ma’am Arlou Angeles September 23‚ 2013 I. Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of

Gravimetric Determination of Calcium ABSTRACT Determining the mass of a pure compound is a method of a gravimetric analysis. One of the gravimetric analyses is the precipitation; it is a method of separating the analyte from the unknown sample as a precipitate where it will be filtered and converted into a known composition that can be weighed to determine its mass (Skoog et al‚ 2013). Determining the mass of calcium by using gravimetric analysis was the objective of the experiment. A 25 mL of

pleasant‚ fruit-like odors and are the chemicals responsible for the odors and flavors of many fruits (oranges‚ bananas‚ pineapples) and flowers. In most cases‚ such natural products get their properties from a mixture of organic compounds. In this experiment you will prepare two esters of o-hydroxybenzoic acid‚ more commonly known as salicylic acid. One of the esters‚ acetylsalicylic acid‚ is aspirin‚ the common analgesic. We will synthesize aspirin by mixing salicylic acid with acetic anhydride. The

I believe in determination‚ determination is something that everyone should have. I’m an athlete and I think that every athlete should have some sort of determination. Determination is having your mind set on something and fulling that to the best of your ability. Every person should set goals in their life and to be able to accomplish those goals you need to be determined. This year I ran cross country. I hate running but I was determined not to give up cross country just because I hate running

for Drilling on Federal Land The United States had great choice to make this past month in the Presidential Elections. The decision was to continue on our current path or start on a new one. A major point on the two candidates was on the domestic economic policies. Issues on the domestic economic policies were very different for both tickets in this year’s election. Differences were very clear on each party’s stances on drilling on Federal Land. Romney was very adamant on increasing drilling on
