Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant. This point of equilibrium is referred to as the Kc value‚ which can be obtained using the formula: Kc = [product] [reactant] In this experiment‚ we used a spectrophometer to

I.History Trung nguyên is the most famous coffee brand in Vietnam. It was created in 1996 by Mr.Đặng Lê Nguyên Vũ. During student life in medical school of Tây Nguyên‚ Mr.Đặng had a question about coffee farmers’ life. Although the price of a cup of coffee wasn’t cheap‚ but why‚ farmers were still poor. This question encouraged him to find the answers. He and his company suffered from many accidents‚ but they kept on trying. Those experiences brought them a good background for opening more shops

The story seems to begin in Ethiopia‚ where the coffee berry grew wild. Goatherds there noted that goats which ate leaves and berries of the plant remained awake all night. The Arabs claim that they developed the plant during the reign of Mohammed (c675 AD). Believe that if you wish - we are going with the Ethiopian story. Consumed originally as a food‚ it would take on the character of a medicinal and eventually that of a social drink. The coffee tree grows to a height of 14 to 20 feet‚ producing

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

Coffee is the world’s second largest traded commodity it is used not only for drinking but for soft drinks and cosmetics as well‚ it is second only to oil according to all imports and exports from all countries. They are two main types Arabica coffee (most people are used to this and are more popular) and there is Robusta coffee. In the last two years the prices of coffee have been gradually falling (Ycharts. (2013). Coffee Arabica Price) alongside this‚ the supply of coffee has also been falling

The Equilibrium Constant of an Ester Hydrolysis Reaction CHM 152LL Section 33263 March 28‚ 2014 John Weide Abstract: The purpose if this experiment is to determine the equilibrium constant of an unknown alcohol. In this experiment unknown alcohol number three and unknown ester number three were used. The equilibrium constant was found by titrating a series of reactions containing H2O‚ HCl‚ and the unknown ester with only the last solution containing the unknown alcohol
