Percent of Water in a Compound CHEM 1315-022 For experiment one‚ The Determination of the Percent of Water in a Compound‚ the sole purpose of conducting this experiment was to determine the percent of water found in compounds such as Magnesium Sulfate‚ Copper Sulfate‚ and so on. Along with determining the percentages of the hygroscopic compounds the experiment allowed for the exploration of separation of hydrogen bonds to ionic solids through the use of heat. The reason that the water clings to

The Center for Disease control has estimated that illnesses directly resulting from food contamination cause approximately 76 million illnesses‚ 325‚000 hospitalizations‚ and 5‚000 deaths each year in the United States. The rise of food-related illnesses can be mostly attributed to increased eating out. Half of every dollar spent on food in this country is spend on food prepared outside of the home. As the amount of people involved preparing our food rises‚ so does the risk of contracting an illness

Pennsylvania State University Lab Report on Experiment 10- The Chemistry of Natural Waters Introduction What is water hardness? Water is extremely important to all living things and even to non-living things‚ indirectly. Therefore‚ the way water travels and gets to a place is also extremely important because its transportation methods determine the chemicals that get involved and added into the water as it travels. This relates to the hardness of water. The hardness of water is basically caused by the

following Aβ-injection [19]. 2.5. Behavioral test: Morris water maze (MVM) 2.5.1. Apparatus The Morris water maze test was conducted as described [20‚ 21]. The maze consisted of a circular pool (200 cm in diameter) filled with water (23±2°C) to a depth of 40cm. The circular pool divided into four arbitrary quadrants. A transparent Plexiglas platform (the only escapable thing from the water) 10cm in diameter was submerged 2cm underneath the water surface at the midpoint of one quadrant. There were many

McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel
