Oxidizing Magnesium AIM: To determine the empirical formula of MgO RAW DATA COLLECTED: Mass of Mg/g | Mass of O2/g | Mass of MgO/g | 0.12 | 0.07 | 0.19 | 0.15 | 0.08 | 0.23 | 0.16 | 0.08 | 0.24 | 0.19 | 0.11 | 0.30 | 0.21 | 0.11 | 0.32 | 0.23 | 0.09 | 0.32 | CONCLUSION: When a mass of magnesium is burnt in air‚ it combines with the oxygen molecules to form magnesium oxide. The graph doesn’t completely verify the empirical formula of magnesium oxide. There is a slight difference

Why Do People Seek Revenge? “An Eye for an Eye” that’s what most people say when it comes to revenge. People don’t consider their decisions are right or wrong‚ all they think about is how to get their revenge with people that tend to harm them or humiliate them. It seems like a trigger that is waiting to be pulled‚ so when someone says or does something that is extremely upsetting it develops a tremendous desire to seek revenge. Revenge develops negative behavior toward others‚ that can lead

The purpose of this lab was to find the empirical formula for magnesium oxide. To find this formula‚ a strip of Magnesium ribbon was burned in a crucible over a flame from a bunson burner. After the strip caught fire multiple times with the cover on‚ and 10 drops of distilled water were added‚ and the crucible was lightly heated. The crucible was then weighed and the mass recorded. Calculations were performed and the mole ratio of Mg to O was recorded. The results of other lab groups performing

ANTACIDS- Classification and Mechanism of Action INTRODUCTION Antacids are defined as a substance‚ generally a base‚ which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux‚ gastritis‚ upset stomach and heartburn. Hydrochloric acid is secreted by the stomach to kill harmful organisms‚ aid digestion and activate digestive enzymes. Excess secretion of acid into stomach or impaired resistance by

could see Web2.0 was moving into companies with Enterprise 2.0. To get involved with this emerging trend we built and launched an Enterprise 2.0 informational website. The website proved to be great experience but did not and was not going to make us money. We decided we wanted to develop software but we needed to work out what we were going to build. Reflecting back I think we spent too much time figuring out what to do. It seems that this is a common problem for start-ups. We now know what we

product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected
