The global market for polyvinyl chloride (PVC) is expected to reach USD 79.11 billion by 2020‚ according to a new study by Grand View Research‚ Inc. Increasing construction and infrastructure spending in emerging markets of Asia Pacific and Latin America is expected to remain a key driving factor for global PVC demand. In addition‚ growth of global automotive industry is also expected to have a positive influence on the market. Volatile raw material prices coupled with the stringent regulatory scenario

In my coursework I will investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying

Purpose: The purpose of this experiment is to determine the number of moles of water molecules of crystallization of a sample of hydrated Barium Chloride. This can be calculated using Gravimetric Analysis and to indirectly determine the percent composition of a hydrate by taking advantage of its chemical properties. Introduction: Gravimetric procedures are analytical methods in which the results are determined from the masses of starting materials and products. These methods

MAGNESIUM LAB Introduction The purpose of this lab experiment is to determine the atomic weight of magnesium by measuring the amount of hydrogen gas evolved when hydrochloric acid reacts with magnesium. The reaction is as followed: Mg + 2HCL H2 + Mg2+(aq) + 2Cl-(aq) In this experiment there is a one to one relationship between the number of moles of hydrogen gas evolved and the moles of magnesium metal consumed in the reaction. Therefore in the finding of the experiment moles of H2 evolved is

partner: Date: Title: Determination of the valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction (that is‚ how

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

reaction. The reaction begins by first converting the m-toluic carboxylic acid into an acyl chlorosulfite through a reaction using thionyl chloride. The carboxylic acid is converted into an acyl chloride because the acyl chloride is more reactive. In this step‚ hydrochloric acid is formed from a hydrogen on the carboxylic acid and a chlorine from the thionyl chloride atoms binding together. A chlorine atom then attaches itself to a double bonded oxygen on the acyl chlorosulfite‚ kicking the double bonded
