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

Finding the formula of magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Eye protection must be worn Apparatus Crucible and lid

What is Magnesium chloride(MgCl2)? What is it used for and why? What does it look like? Magnesium chloride is the name of a chemical formula of MG CL two. This is a salt and they are a typical ion halide. halides are very soluble to water. magnesium chloride is used for deicing on highways in sidewalks and also parking lots it is a good source of de-icing. The color that it appears is white or colorless crystalline solid. What is magnesium or what is chloride? whare are they located? You can find

Book Burning Book burning refers to the destruction of books and other written materials and it was usually done out in public. On May 10 the Nazi German students association gathered‚ books on the 300th anniversary of lathers 95 to hold a festival where they would burned books that the students found “Un-German‚ to cleanse by fire. They called it the action against the Un-German spirit.” Local chapters had to offer blacklists of “Un-German authors. They would burn about 25‚000 books while throwing

ABSTRACT Open burning is the disposal of any waste material in an open‚ outside flame and can be a substantial wellspring of air contamination. Smoke from open burning contains fine particles‚ gasses and other harmful results of burning that can be breathed in profoundly into the lungs. Exploratory studies have interfaced presentation to fine particles to trouble in breathing

In the wake of perusing the article I have shaped my sincere beliefs about cross-burning. I don’t concur with cross-burning on the grounds that the cross speaks to heavenliness for Christians. In spite of the fact that everybody doesn’t have similar convictions‚ cross-burning is an objective against a specific gathering of people. I do trust cross-burning ought to be ILLEGAL furthermore‚ it ought to be considered "hate act" and a risk. The constitution ensures the privileges of its nationals. The

Heat of Formation of Magnesium Oxide Objetive: To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law‚ which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction: Chemical reactions require heat energy to complete‚ called an endothermic reaction‚ or produce heat energy‚ and thus called an exothermic reaction. The heat energy produced by such reactions can be measured using a calorimeter‚ a piece
