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

Being a drill sergeant may be the most challenging and rewarding assignment a Noncommissioned Officer will ever experience during his or her military career. The Drill Sergeant Program began as a pilot course. The course was a very selective training school‚ in which required attendees to possess certain criteria to be considered for enrollment and eventually become a highly qualified recruit trainer- a Drill Sergeant. Based on an organizational meeting‚ the United States Continental Army Command

The Scholarship Jacket Racism is a well known problem throughout this world. We get judge every day whether its our race‚ the way we dress‚ the way we talk‚ how we do academically‚ and if were going to succeed in life based on others people way of thinking what success is. The following story that I read is an excellent example of the way people underestimate us just because of our race or where we stand in society. “The Scholarship Jacket” by Marta Salinas is about a young girl wanting to figure

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

Metals & Non-Metals Metals: Good conductors of heat and electricity. Have shining luster. Malleable (this means that they can be hammered or distorted). Ductile (this means that they can be drawn into wires). Most have high melting and boiling points. Are sonorous (give out sound when beaten). Usually solid at room temperature. An exception to this is mercury‚ which is liquid in nature. Examples: Aluminum‚ Gold‚ Copper‚ Silver‚ Sodium‚ Potassium‚ Mercury. Corrode or oxidize in

Chemistry Introduction Objective: The goal of the chemistry unit is to teach students how to identify when a chemical reaction has occurred. The students should be able to watch a process and determine if a chemical reaction has occurred. They will see (and usually perform) reactions demonstrating every type of chemical change. Background: Chemistry is the study of chemical reactions as a result of molecular interaction. There are four ways to determine if a chemical reaction has occurred
