Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

Chemical Equilibrium: Le Chatelier Principle By Sarah Ramos and Kristina Todorovic Chemistry 203 DEN Dr. Mohamed El-Maazawi Part A. Acid-Base Indicators Purpose In this part of the experiment‚ we will find a reagent that will shift the acid-base equilibrium reaction described by Equation (2) in one direction and then a second reagent that will cause the equilibrium position to shift back in the opposite direction. Introduction An acid–base indicator

Diversity is described as the state of having people who are of different races or who have different cultures in a group‚ but diversity can be more than just race or ethnic background. When we are talking about workplace diversity‚ we are referring to the variety of differences between people in an organization. Diversity encompasses race‚ gender‚ ethnic group‚ age‚ personality‚ cognitive style‚ tenure‚ organizational function‚ education and background. The effects of diversity can impact how

Those hard-to-pronounce chemicals that are in the list of ingredients on the label are used for more than just flavoring‚ appearance‚ and preserving the food (Food Additives). Those additives are used in some other very harsh items such as bug repellent (Food Additives). However‚ there are some simple and sustainable options that can help consumers avoid running into harsh chemicals and additives that may be lurking in their food. These changes will not

The Oxford English Dictionary defines diversity as “the state of being diverse” (OED par 1). The word diversity originates from the Middle English diversite‚ an English root meaning‚ “to turn aside” (OED par 4). Diversity personifies a cross-culture exposure to develop openness approaching distinctive personalities and perspectives to improve human connection with a variety of people. Yet‚ human diversity may connote issues of ethnicity and may struggle with the continuation of addressing the

Chemical Castration LaDarius D. Abraham Southern University A&M College Sex offenders have been a serious problem for our legal system at all levels‚ not to mention those who have been their victims. Sadly‚ many of those assaults are perpetrated by people who have already been through the correctional system only to victimize again. Sex offenders‚ as a class of criminals‚ are nine times more likely to repeat their crimes (Oakes 99). This presents a problem for the public‚ as potential victims

Three things are usually required for a chemical explosion: a chemical reaction that occurs very rapidly‚ a large increase in gas pressure‚ and a confined-reaction vessel in which the pressure of the gaseous products can increase to a point that the gases break violently out of the container. In this chemistry and physics science fair project‚ you will use the combustion of ethanol to provide energy for a small explosion. The chemical equation that describes the combustion of ethanol is shown below
