BACKGROUND Continental drift is a theory proposed by a scientist‚ Alfred Wegener in the twentieth century. The theory explained that all the continents was once joined as one‚ and through the course of millions of years‚ drifted apart from each other to form separate continents as we see it now. THEORY Before all the continents were separated‚ they existed as one supercontinent‚ Pangaea (Lovett‚ 2008)‚ surrounded by a super ocean‚ known as Panthalassa. Movement of continents can be compared to

Experiment No. 2: Dynamic Equilibrium and Le Chatelier’s Principle December 1‚ 2011 Final Formal Results Le Chatelier’s Principle states that “when a stress is applied to a chemical system at equilibrium‚ the equilibrium shifts in a direction that reduces the effect of stress” (Gross‚ Abenojar‚ and Tan 23). Moreover‚ it helps us “predict the direction of the shift of the equilibrium” (Silberberg 745). Silberberg also stated that there are three kinds of disturbances - concentration‚

of this lab is to experimentally determine the equilibrium constant‚ Kc ‚ for the following chemical reaction: Fe3+ (aq) + SCN-(aq) ↔FeSCN2+(aq) Background Information: A system is at equilibrium when the rate of the forward reaction is the same as the rate of the reverse reaction. There is no change in concentration for the reactants or products at chemical equilibrium. When the system is disturbed there is a shift to reestablish equilibrium explained by Le Chatelier’s Principle. It states

Determination of the Equilibrium Constant for Ferric Thiocyanate In this laboratory exercise‚ the equilibrium constant(Kc) for the reaction between the Ferric Ion (Fe3+) and the Thiocyanate Ion (SCN-) was determined. After measuring the absorbance of the Ferric Thiocyanate‚ and carrying out some calculations; it was determined that Kc=130.81M Introduction: Chemical equilibrium is established when a reaction exists in a state where the forward reaction rate is equal to its reverse reaction

DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

price above the equilibrium price reduces social welfare In a free market demand and supply alone determine the price. This means that quantity of demand and quantity of supply equate at this point is where the price is set which is therefore called equilibrium price.

What is Strategic Planning? Explain its relevance to the management of a Human Service Organization of your choice. What is building a house without a blueprint? In everything we do‚ planning is essential‚ it serves as a guideline. With reference to the question‚ strategic planning offers many benefits to social service organizations‚ operating within an environment‚ funding cutbacks and emerging competition‚ (Finley et al‚ 2001). According to Florence Green (2009)‚ strategic planning is an
