The Effect of Chemicals on Fire In this lab we got to see the effect of chemicals on fire. We got to. See the flames change to different colors. The size of the colorful flame depended on how the Bunsen burner was turned on. I was sick when we were supposed to have the lab read‚ but I got it read the next day before class. During the lab I made sure to have the correct attired on: my goggles and apron. Ow ill go ahead and tell you five good safety precaution tips. One‚ never leave a lit

Chemical Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent

Chemical changes are irreversible because substances mix and cause a reaction which creates a new substance. Chemical changes can be caused when a substance is combined with a heat‚ water or another substance. Heat can cause a chemical reaction called caramelisation which is when sugar is heated at a high temperature causing it to break down. This gives the sugar a nutty

Classes of Chemical Reactions Whenever a reaction takes place‚ energy is changed as well when the substances react chemically. Scientists have taken these changes in energy and generalized them. Scientists can take these generalizations and discover more about the nature and tendencies of matter. In this lab‚ the purpose was to perform seven reactions‚ write down their equations‚ and identify the type of reaction. In this lab report‚ several methods of displaying this information will be applied

Summary Standard Chemical is a company that processes volatile toxic chemicals that are sold for commercial use. The HR manager‚ Jacobson‚ attended a drug and alcohol abuse seminar and realized that the company did not have a policy. Safety is a critical issue at Standard Chemical because of the potential environmental hazards; therefore‚ the HR manager thought it would be smart to implement a drug and alcohol abuse policy. To make sure the managers do not abuse this new policy to get rid of unnecessary

of Experiment: Observation of Chemical Changes Purpose: To examine the reaction of common chemicals from household consumer products‚ and the changes they undergo. Procedure: After combining the chemicals listed below in Data Table 1‚ I observed the mixture against white and dark backgrounds by slipping white and black paper underneath the well plate. For every reaction‚ I wrote down the chemical combination‚ the well number‚ and my observations of the chemical reactions against the white and

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

Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate
