Formula of Magnesium Oxide‚ students set out to find if there is a true 1:1 ratio in the empirical formula of MgO. This was determined by burning the Magnesium until a white smoke started to protrude. This showed the reaction of Oxygen combining with Magnesium to form Magnesium Oxide. This was then measured again and turned out to be slightly heavier than the measurement before. This added weight is Oxygen‚ forming the combustion of Magnesium Oxide. The formula for Magnesium Oxide is 〖〖Mg〗_1 O〗_1‚ a

The Verification of the Molecular Formula and Percent Composition of the Compound Magnesium Oxide (MgO) Nice sounding title Date Performed Lab: 8/31/06 Purpose: 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

Matter: A Comprehensive Overview of Nitrous Oxide Abuse Ryan Ardelle Anatomy & Physiology‚ Period 3 Mr. Syvret Due: March 14‚ 2013 SUBSTANCE OVERVIEW The issue of inhalant abuse is a multifaceted problem‚ stretching across many communities and locales in the entirety of the United States. Inhalants as a class of drug vary widely‚ ranging from volatile solvents and aerosol propellants‚ to more broadly‚ any drug delivered by inhalation. Nitrous oxide straddles these categories‚ as it finds use

The Synthesis and Determination of Empirical Formula for Magnesium Oxide Aim: To determine the empirical formula for magnesium oxide. Data Collection: Table 1 Mass of empty crucible‚ crucible + Mg (roughly 1cm pieces of a 15-cm piece of magnesium ribbon)‚ and crucible +MgxOy. (mass measured with an analytical balance). The mass of crucible + MgxOy was obtained after a continuous process of heating‚ letting cool‚ heating with water enough to immerse the content and letting cool of the Mg. Mass

low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated by the same methods as benzene derivatives‚ including the well-known “mixed acid” method that utilizes a mixture of nitric acid and sulfuric acid. The electrophile
