IONIC COMPOUNDS In chemistry‚ an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually‚ the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together by the electrostatic forcesbetween oppositely charged bodies. Ionic compounds have high melting and boiling points‚ and they are hard and very brittle. Ions can be single atoms‚ as the sodium and chlorine in

From the thousand yard stare to a well kept hair cut‚ military bearing is prevalent in every facet of military life‚ though military bearing is much deeper than just appearances; it is the cornerstone of any military career. Military bearing encompasses every facet of life in the military and can be applied to any situation. Military bearing itself is gleaned from several places such as‚ the articles of the UCMJ‚ The eleven general orders of a sentry‚ as well as our own Sailors Creed. From these

In 2009‚ Google has created PiLab to improve people’s operation. PiLab initiated Project Oxygen to research the impact of managers on employees and methods to enhance management. Google’s problem now is how to implement the research to increase efficiency for management. There are three alternatives which are to study senior management and executives‚ providing guidance to team composition and to study the complete life cycle of managers. The criteria used to evaluate each alternative are whether

use ultimately come to us through trees and vegetation. Trees play an important role in purifying the air around us. They breathe in carbon dioxide and breathe out oxygen that sustains our life. Thus they make this world a better place to live in. Trees are also very necessary for having good rainfall. The trees attract rain bearing clouds and prevent soil erosion and conserve the earth. Our Government also realised the importance of trees. The ’Chipko Andolans’ and "Van Mahotsava’ made us all

Oxygen Cycle Required for Life All living things use oxygen or depend on organisms that use oxygen in some way. All Animals and Other Consumers Use Oxygen We use oxygen to break down simple sugar and release energy. This can be done through respiration or fermentation. Animals mainly use respiration.

Introduction: An oxygen sensor‚ or lambda sensor‚ is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under supervision by Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. The most common application is to measure the

Why Oxygen is Important Oxygen plays a vital role in the treatment of patients. Oxygen is the molecule that helps the cells in our body produce ATP through a process known as cellular respiration. Also it is the number one drug of choice for the American heart association. Finally it is a priority according to the universal care protocols in the protocol book given to flight medics in USAAAD at Fort Polk. In short Oxygen is important for the medics to use. To start off with oxygen helps sustain
