Name: Keziah V. Cuyom Section: 9 - Malaya Topic: Types of Chemical Reaction A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons‚ leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types. However‚ if

Overview Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years‚ it has also developed into much more advanced chemistry. In this article‚ I am going to focus on the more advanced‚ modern uses of chemical warfare in World War I and World War II. World War

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

PROFESSIONAL RESPONSIBILITY: THE ROLE OF ENGINEERING IN SOCIETY S.P. Nichols and W.F. Weldon Center for Electromechanics‚ The University of Texas at Austin‚ USA Keywords: professional responsibility‚ engineering ethics‚ engineering responsibility. Abstract We argue that the practice of engineering does not exist outside the domain of societal interests. That is‚ the practice of engineering has an inherent (and unavoidable) impact on society. Engineering is based upon that relationship with society

Is Ethics an Alien word to the engineering profession? “The decisions and actions of engineers have a profound impact on the world we live in‚ and society at large” [The Royal Academy of Engineering] and are generally responsible for the way life is on earth due to their key part in discovering innovative technologies throughout the past. However in recent years the engineering profession has come under scrutiny with regards to its ethical stance. Ethics is certainly not an alien word in the United

Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules reacting during chemical changes

Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance
