II Hypothesis: I think that the chemical change is an irreversible process. The wet iron filings by the next day it will turn into rusting material because it is exposed to the atmosphere. While the dry iron filings is not III Materials: The setup in the previous activity‚ small plate‚ dry iron filings. IV Procedure: 1. Place the

UV2493 Version 1.5 DIAMOND CHEMICALS PLC (A): THE MERSEYSIDE PROJECT Late one afternoon in January 2001‚ Frank Greystock told Lucy Morris‚ “No one seems satisfied with the analysis so far‚ but the suggested changes could kill the project. If solid projects like this can’t swim past the corporate piranhas‚ the company will never modernize.” Morris was plant manager of Diamond Chemicals’ Merseyside Works in Liverpool‚ England. Her controller‚ Frank Greystock‚ was discussing a capital project that

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

Chemical Engineering Career Adam Homan Saint Paul College Chemical Engineering Career For my career path I have chosen to become a chemical engineer. A chemical engineer is considered in my opinion to be a universal engineer‚ exploring all facets of life. The responsibilities of a chemical engineer can vary but first start with a problem that leads to an idea and then a hypothesis. Following those first steps includes a lot of research involving many check points along the way to ensure

2014 Lab report #1 on chemical and physical properties/ changes Introduction Summary: The purpose of this experiment is to allow students to understand how to differentiate physical and chemical properties and reactions of matter by observing changes of matters under circumstances. Physical properties are properties of matter that can be observed without changing the composition of the matter‚ including the volume‚ mass‚ color‚ density‚ and shape of it. Chemical properties include the matter’s
