Determining the Empirical Formula of Magnesium Oxide Lab Purpose The purpose of this lab was to determine the percent composition and empirical formula of magnesium oxide. Hypothesis If a strip of pure magnesium metal reacts with oxygen in the air to create magnesium oxide, then the molecular formula will be MgO. The percent composition for magnesium oxide would be 60.31% magnesium and 39.69% oxygen. Apparatus Refer to attached sheet Procedure Refer to McGraw-Hill Ryerson Chemistry

Task 1b Practical analysis The products of the practical were typical for an acid-base titration with carbonate, which are sodium chloride, carbon dioxide and water. The balanced equation for the practical is Na2CO3 + 2HCl = 2NaCl + CO2 +H2O. This is because the as you add the hydrochloric acid to the sodium carbonate the chlorine displaces the carbon and oxygen which then becomes carbon dioxide and water with the lone hydrogen. Ionic bonding is when a metal gives an electron(s) to a non-metal

catalase has been raised because more particles have been exposed to the other reactant, which lead to a higher rate of collision between the particles of reactants. Thus, there’s a higher chance to gain the activation energy in order to carry out chemical reaction. Rate of reaction increased. Catalase was a biological catalyst (enzyme) which made of protein and will denature in high temperature due to the breakage of bond between molecule. In this case, boiling the liver will cause the enzyme inside

division of DuPont that produced paint for the auto and trucking industries. From the beginning of Kullman’s term as CEO in January 2009, she sought to transition the Company from an economically struggling commodity chemical business (with a 2009 stock price below $19) to a specialty chemical and science-driven business (Exhibit ). Kullman believed DuPont was best positioned for a future at the core of industrial biotechnology by competing in agriculture, nutrition, and advanced materials, areas with
