metals arranged in order of their reactivity based on displacement reactions‚ reduction of their oxides by hydrogen or carbon‚ the relative ease of decomposition of their compounds and reactions with oxygen‚ dilute acids and water. The higher up a metal is in the reactivity series‚ the more reactive it is. In the experiment conducted‚ the three metals‚ magnesium‚ zinc and copper each had to undergo displacement reactions and reactions with water‚ oxygen and dilute acids‚ to arrange them in the order

Coupled Reactions Louella Rose E. Tan‚ Frances May L. Coralde Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion A combustion reaction is a reaction that liberates heat and light. Magnesium is a stable element and reacts violently with evolution of much heat and light. The reason the magnesium burned in carbon dioxide was because it combined with the oxygen in the CO2 leaving elemental carbon behind. CO2(g) C(S) + O2(g)

Case 20: Diamond Chemicals plc (A) --PT07 Group 10 INTRODUCTION: Diamond Chemicals is a large worldwide chemicals producer with two factories in Liverpool England and Rotterdam Holland. Both of their plants were built in 1967 with annual output of 250‚000 metric tons polypropylene. Compare with low-cost producer‚ the production cost per ton is 1.09 which is a little bit high than competitors (see Exhibition 1). With the decline EPS from £60 in 1999 to £30 in 2000 and worldwide economic slowdown

WGP CHEMICAL COMPANY CASE STUDY 1. What is the total distribution cost for W-G-P Chemical Company? What is the cost per pound‚ cubic foot‚ case‚ line‚ and order? How can these measures contribute to the distribution review process? In order to calculate the total distribution cost‚ carrying cost must be calculated. Inventory carrying cost rate was given as 18%. The formula is Annual carrying cost=average inventory level * carrying cost rate Average inventory was given in table 4 as $90 million

Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its
