Oxidation & Reduction I. Metal-Metal Ion Displacement II. Halogen Displacement Reactions INTRODUCTION A series of experiments had been conducted to determine the order of displacement strengths of the metals and halogen chosen for the experiments. A displacement reaction is a reaction in which one element(metal or non-metal) displaces another element(metal or non-metal) from its salt solution. In the displacement reaction of metals‚ the more electropositive metal will displace the less

Chemistry - Module 2 - Metal 1. Metals have been extracted and used for many thousands of years * Outline and examine some uses of different metals through history‚ including contemporary uses‚ as uncombined metals or as alloys. Contemporary Uses of common metals Metal | Uses | Iron and Steel (an alloy with <2% carbon)Good tensile strength‚ cheap‚ rusts (corrodes) | - Railways‚ bridges‚ buildings- motor cars bodies‚ ships and trains- Engine blocks‚ fire hydrants‚ drainage

My name is Deontaye Chisholm and I run and own Safety Comes First Consultants. I have been contacted by a local welding company that has just been issued several serious safety citations for violating 29 CFR 1910.252 (a) (2) (iii) (B) and 29 CFR 1910.252(b) (2) (i) (A). My service has been retained and I have scheduled a meeting with management to discuss an immediate action plan to implement corrective actions at their facility. I open up the meeting with a brief introduction of my company’s

Metals and Non-metals Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Metals: Part - I Physical Properties of Metals:- Hardness:- Most of the metals are hard‚ except alkali metals‚ such as sodium‚ potassium‚ lithium‚ etc. Sodium‚ potassium‚ lithium etc. are very soft metals‚ these can be cut using knife. Strength:- Most of the metals are strong and have high tensile strength. Because of this big structures are made using metals

"Welding With Children" Language Analysis "He just stared at me‚ and i saw that he had no idea of what late was. Glendine‚ his mama‚ probably lets him fall asleep in front of the set every night. I pictured him crumpled up on that smelly shag rug she keeps in front of the TV to catch the spills and crumbs" (2). Within the passage it mentions that the child had no idea what late was. This indicates that his life is easy because he can fall asleep whenever he gets tired without a problem like he

Prof. A.R.Santha Kumar 3.3 Welding and welded connections Welding is the process of joining two pieces of metal by creating a strong metallurgical bond between them by heating or pressure or both. It is distinguished from other forms of mechanical connections‚ such as riveting or bolting‚ which are formed by friction or mechanical interlocking. It is one of the oldest and reliable methods of joining. Welding offers many advantages over bolting and riveting. Welding enables direct transfer of

Understanding “Arc Flash” Simply put‚ an arc flash is a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another‚ or to ground. The results are often violent and when a human is in close proximity to the arc flash‚ serious injury and even death can occur. Arc flash can be caused by many things including: Dust Dropping tools Accidental touching Condensation Material failure Corrosion Faulty

physically. Through the DMACC welding course‚ I would recieve my welding certificate to be able to weld commercially through DeeZee‚ Vermeer or another company of that prestige. Through the cost of the course itself and material needed‚ the cost of the entire class can spread through the thousands. Through the money granted‚ it will help me pay for the course then with that I can purchase the equipment needed outside of the course to then further my career and my path into welding.
