Chemistry is the branch of science that deals with the structure of organic and inorganic matter( any substance or organism which has a mass and occupies space)‚ its properties and reactions; however chemistry is primarily the study of reactions that any given substance takes on when interacting with another substance. Chemistry is the main incentive for the life that we live today; it has provided modern society with facilities that make our day to day lives easier. Predominantly chemistry has allowed

THE IMPERATIVES AND BENEFITS OF NUCLEAR ENERGY 1. INTRODUCTION Only 30 years ago‚ nuclear energy was an exotic‚ futuristic technology‚ and the subject of experimentation. Today‚ nuclear energy is America’s second largest source of electric power after coal; more than 110 nuclear energy plants supply more electricity than oil‚ natural gas or hydropower taken together. Nuclear energy is a clean‚ safe‚ reliable and competitive energy source. It is the only source of energy that can replace

SCI215 M4-Assignment 1: Discussion—The Promises and Perils of Nuclear Power Nuclear power refers to the generation of electrical energy by controlled nuclear reactions. These reactions produce heat‚ which in turn creates steam that runs the generators to produce electricity. Approx. 1/8 of the electricity worldwide generated comes from nuclear energy. In this task‚ you will analyze the use of nuclear energy as a resource energy. * Discuss the scientific and technical concepts related to

colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium). A colloidal system may be solid‚ liquid‚ or gaseous. Many familiar substances are colloids‚ as shown in the chart below. As well as these naturally occurring colloids‚ modern chemical process industries utilize high shear mixing technology to create novel colloids. The dispersed-phase particles have a diameter of between approximately 5 and 200 nanometers.[2] Such
