A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions‚ the London dispersion force and hydrogen bonding

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a

History The first structured method for documenting process flow‚ the "flow process chart"‚ was introduced by Frank Gilbreth to members of the American Society of Mechanical Engineers (ASME) in 1921 in the presentation “Process Charts—First Steps in Finding the One Best Way”. Gilbreth’s tools quickly found their way into industrial engineering curricula. In the early 1930s‚ an industrial engineer‚ Allan H. Mogensen began training business people in the use of some of the tools of industrial engineering

Chapter 16 Notes The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium‚ which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium‚ the inner portion is called the visceral pericardium (epicardium). Epicardium- outer most layer of the heart wall

matter using physical and chemical properties. Physical properties are characteristics of a substance. Two types of physical properties are quantitative and qualitative. Quantitative is a property that has an amount or can be measured such as hardness‚ solubility‚ and viscosity. Qualitative is a physical description of matter such as color‚ clarity‚ and state. Chemical properties are characteristics of a substance which allows it to behave in a specific manner. A few types of chemical properties are
