The Enthalpy of Formation of Magnesium Carbonate By: Jessica Miller T.A: Thomas Lab Partner: Rebekah Melanson Thursday Lab Room 106 Chemistry 1001-A Due Date: Thursday February 3rd 2011 Abstract The purpose of this experiment was to determine the enthalpy of formation of magnesium carbonate in a lab setting. This was done using a calorimeter‚ which was calibrated by adding a known amount of both hot and cold water. Following the calibration of the calorimeter‚ HCl was placed into the empty calorimeter

overhydration. In this paper I will discuss what over hydration is‚ the symptoms and effects of it and treatment options. What is over hydration? Overhydration is defined as a condition in which the body contains too much water (medical dictionary). There are two types of over hydration. First type is “Increased water intake” ()‚ or water excess and “Retaining water” ()‚ or water intoxication. Water intoxication is the type of over hydration where the body is taking in more water than the kidneys

The Effects of Dehydration and Hydration Water is a necessity in our world today but especially involving the health of human beings. Water is so important to human life that we would not survive without it because people become dehydrated when an insufficient supply of fluids are consumed in a day. “Human survival is dependent on water -- water has been ranked by experts as second only to oxygen as essential for life” (“Health Benefits of Water”). Proper hydration and the avoidance of dehydration

been crystallized from water solutions appear to be perfectly dry‚ yet when heated they discharge large quantities of water. An example can be hydrated copper (II) sulfate. Exactly this salt is used in the described experiment. RESEARCH QUESTIONWhat is the number of moles of water of crystallization associated with one mole of copper (II) sulfate‚ in the hydrate CuSO4 * xH2O (s)? The independent variable in this experiment is sample thermal treatment ( heating and cooling) and the dependent variable
