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

Melissa Carrithers 9-17-14 Period: 6 Determination of the Empirical Formula of Silver Oxide Purpose: To find the percent composition and empirical formula of silver oxide can then be calculated‚ based on combining the ratios of silver and oxygen in the reaction. Hypothesis: Silver oxide decomposes to silver metal and oxygen when strongly heated. Heating Silver oxide causes the oxygen to be driven off‚ leaving only the silver metal behind. The total mass of the products of a chemical reaction must

Erez Manela’s compelling study on the impact of Wilson’s ideology of self-determination on the colonial subjects during the post-World War 1 era. He illustrates roots of the rise nationalism and socialist movements in the colonized territories. He argues that Wilson did not see self-determination as idea to be used by colonized peoples and was‚ in his argument‚ exclusive to the Europeans. This was not what he anticipated through the quick spread of his new ideology through colonies that would soon

motivation is not founded on reinforcement as shown in self-management strategies but rather originate within the individual. The premise that performing a particular behavior brings a sense of enjoyment and fulfillment makes the theory of self-determination. The person performing the behaviors must find performing a given behavior important to meeting his goals as a key motivation to initiate the desired change. The nurse should be available to explain the importance of behavior change and elaborate

Neutralization Titrations: The Determination of Sodium Carbonate from Unknown Soda Ash Unknown # I. Purpose: The goal of this experiment is to determine the weight % of Na2CO3 through the preparation of NaOH and HCl standards. The molarity of the standards will be found through titration of KHP for NaOH‚ HCl vs the known NaOH‚ and the unknown Soda Ash sample vs the known HCl. II. Equations and Sample Calculations: Titration of HCl with NaOH: Complete Equation: HCl (aq) + NaOH (aq)
