Industrial Chemical Processes Essay Tan Hung Kai Grade 11 In our present world‚ there are thousands of chemical processes that are being used to produce products that benefits our daily lives. Industrial Chemical processes are used for “transforming raw materials into useful commercial products for society”. (Dr. Philip Britz-Mckibbin Industrial Chemistry: CHEM 2013) Examples of industrial chemical processes include distillation‚ smelting‚ disinfection‚ and Pyro processing. Even today‚ scientists

Single Parent Households Single Parent Households Family is defined in Webster’s dictionary as “a group consisting of parents and children living in a household together”. But not all families have a mother‚ father‚ and children. Some families only have one parent making it a single parent household. Since the 1960’s single parent households have been increasing year after year. Information provided by the U.S. Census Bureau shows an increase of 3% in single parent homes from 2008 to 2012

several All My Life items and descriptions from John Freyer’s sale listings‚ the item I chose to compare with other EBay listings was his “Road Trip Cooler tag #000154”. I found a similar item on EBay‚ the 36 quart Marine Performance Cooler that was slightly used. The similarities are both items are being sold from everyday people. These items are things that you can get the items for a better and cheaper price than an actual store. Both items being auctioned has a description of the item. It also include

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

The objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice

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

Chapter 6 - Answer Key to Section Review 1-3 Section Review 1 1. What is the main distinction between ionic and covalent bonding? Answer (A): Ionic bonding involves the electrical attraction between large numbers of anions and cations. Covalent bonding involves the sharing of electron pairs between two atoms. Translation: -Ionic bonding happens between a metal and a non-metal (east coast and west coast) -One atom completely donates its valence electrons to another atom -Metals

collected showed that Clorox Household Cleaner was not significantly different than the Clorox Toilet Bowl cleaner. This is due to the fact our calculated P-value was 11.45%‚ which is larger than the 5% maximum allowed to us to be able to support the alternative hypothesis. This indicates there was not support for our alternative hypothesis‚ causing us to reject it. In doing so‚ we had to accept our null hypothesis. Our Null hypothesis states the Clorox Household Cleaner will not inhibit E. coli

CHM1022 Tutorial 2 – Semester 2‚ 2012 (Chemical Equilibria) 1. The reaction 2 HCl(g) +I2(s) [pic] 2 HI (g) + Cl2(g) has Kc = 1.0 x 10-34 at 25˚C. If a 1.00 L reaction vessel initially contains 0.100 mol of each HCl and solid I2‚ what are the concentrations of HI and Cl2 at equilibrium? 2. Consider the following gas-phase reaction and equilibrium constant at 25 oC: 4 HCl(g) + O2(g) [pic] 2 Cl2(g) + 2 H2O(g) The concentrations of all species were measured at a particular
