The Empirical Formula of Magnesium Oxide. Focus Question – Can the mass of magnesium combusted in excess oxygen be used to determine the empirical formula of magnesium oxide? Hypothesis – Combustion of Magnesium will generate data which can be used to calculate the EF of Magnesium Oxide Experimental Report: Data Collection and Processing Qualitative Observations: * The Magnesium burnt with a very bright flame. (as seen in figure 2 below) * White smoke was formed and some

Introduction The following report shows that the proposal of the modernisation project should obtain funding from the corporate headquarters of Victoria Chemicals. The project has an initial outlay of GBP12 million to renovate and rationalise the polypropylene production line at Merseyside plant. This is done in order to make up for deferred maintenance and exploit opportunities to achieve increased efficiency. This report will look at the following four main areas of concern in order

What is it meant by relative formula mass? How is it calculated using the periodic table? Each element has a relative atomic mass. When a compound is made‚ these relative atomic masses are added together to calculate the relative formula mass of the substance. For example the atomic mass of Na is 23 and the atomic mass of Cl is 35.5 so the relative formula mass of NaCl is 58.5 How by using RFM is it possible to work out amounts of a substance in terms of moles? The compound I was using in my

Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

Formula for Grade Average Calculation There are 3 grade averages: TGA‚ CGA and GGA. TGA (Term Grade Average) is the combined grade average covering all courses taken in the term and the session immediately following. CGA (Cumulative Grade Average) is computed based on all the courses taken by the student which are expected at the time of calculation to be applied towards the degree requirements in the current program. TGA & CGA = Sum of (Course Credits x Course grade points) Sum of Course Credits
