I. Introduction There are two types of chemical reaction that occur one goes only in one direction and the other one is reversible. A reversible reaction is when a products starts to form the backward reaction starts where the products turns back to reactant molecules. When the rate of forward and backward reaction is already equal and the concentrations of the reactants and products no longer change with time we can say that chemical equilibrium is already achieved. A reaction is said to be at

Witch craze in Europe during: the period of the Protestant Reformation‚ Catholic Counter-Reformation‚ the Scientific Revolution‚ and the consolidation of national governments from about 1480-1700 For more than two hundred years‚ individuals were persecuted as witches throughout the continent of Europe‚ even though the witch hunt was concentrated on Southwestern Germany‚ Switzerland‚ England‚ Scotland‚ Poland‚ and parts of France. In a collective frenzy. witches were sought‚ identified‚ arrested

a reaction. Moreover‚ it also tells you how a particular mixture of chemicals will react. This is because chemical reactions always occur in the direction which will make the ratio of their products to reactants equal to the equilibrium constant. In chemistry‚ Le Chatelier’s principle‚ also called Chatelier’s principle or "The Equilibrium Law"‚ can be used to predict the effect of a change in conditions on a chemical equilibrium. The principle is named after Henry Louis Le Chatelier and sometimes

a senior credit representative of Joyce Chemical Company. My task in this case is to look into Eliot Manufacturing and to see if we should continue or terminate our relationship with them. If we were to continue‚ the choices would be to either have them in a program to reduce their accounts payable or to tolerate gradual increases in credit. After doing an analysis on Mr. Pound and the Eliot Manufacturing Company‚ I would recommend that Joyce Chemical Company should terminate their relationship

the rate of decomposition of hydrogen peroxide.” Chemical equilibrium is the state of constant composition attained when opposing reaction rates become equal. There is an essential relationship between reaction rates and chemical equilibrium‚ one that we can describe quantitatively. At first thought‚ the connection may seem obscure - do we not need to be far from equilibrium to properly measure reaction rates? The dynamic nature of chemical equilibrium means that both forward and reverse reactions

portrayals of the Middle Ages refers to a period of isolation and fragmentation in Europe. Although this may have been the case in some areas‚ shipbuilding advanced in Scandinavia under the Vikings. The Vikings invented a narrow ship design that promoted speed and maneuverability. The extraordinary advancements of Viking shipwrights and seafarers allowed the Vikings to become more successful than their counterparts in medieval Europe due to their superior building techniques‚ capability to perform different

I. Write a 1- page essay on The Higher Education in Europe and emphasize the role of education in people’s lives. Education is associated in my mind with moral principles such as the respect for the people around us‚ honesty as well as knowledge from different fields of activity and competences. The part that teachers play in students’ lives is to prepare them for the world beyond the gate of the school. The general trend nowadays goes towards increasing the number of high school graduates
