Communism: On ice advantage? An iconic period in time where the world held their breath‚ not when the air hung stale over the threat of an inter- continental nuclear war was possible but comparably so during the 1972 Canada vs. Russia summit series. Ideally this should have not caused as much as a stir as it did‚ the threat of an all out nuclear war as over and a detente had been called. With two hockey loving countries buying for the title things did get especially heated both on the ice and in the

Complexometric Determination of Water Hardness 9/12/2013 Abstract: Two sets of acid-base neutralization titrations were conducted for experimental analysis. The first set of titrations was to standardize a solution manufactured in the lab. An approximate solution of Na2EDTA of 0.004 M was titrated against a known solution of 1.000 g CaCO3/L to deter mine to exact molarity of the Na2EDTA. Ca2+ + Na2EDTA → CaEDTA + 2Na+ The second set of titrations was to use the now standardized Na2EDTA

Introduction The Diels-Alder Reaction is a reaction used in organic chemistry that builds rings very efficiently (1)‚ this cycloaddition process allows for the stereoselective formation of cyclohexene rings possessing as many as four contiguous stereogenic centers (3). This reaction occurs without intermediates‚ in a single step‚ which explains the stereospecificity due to substituents not being given the chance to “switch around”. (1)These six membered rings are synthesized by reacting a dienophile

Checkpoint Patient Self-Determination Act In 1990‚ The Patient Self-Determination Act began. This Act would require that healthcare facilities inform patients about their right in case of an emergency situation. Also the patient would be informed about their rights to get advanced healthcare accommodations‚ and any related information that pertains to the legal impact and state laws regarding all healthcare decisions. Many of the healthcare facilities that exist today in America would

ALS Helpful or Hurtful The ALS Ice Bucket Challenge went viral on social networks‚ but is it too successful for its own good? ALS (Amyotrophic lateral sclerosis) often referred to as “Lou Gehrigs Disease‚” is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord (ALS Association). It’s like Parkinson’s on super-steroids. Now‚ the challenge aspect was a simple dare. You had 24 hours to drench yourself in a bucket of ice water‚ and if you didn’t complete

Indirect determination of ∆H via Hess’s law Conclusion & Evaluation Research question: What is the ∆H/mol of hydration of CuSO4 (anh)? The ∆H/mol of hydration of CuSO4 (anh) is -70.2‚ according to the experiment done in class. It was determined by applying the Hess’s law‚ using two reactions 1) CuSO4-5H2O ----> CuSO4 (aq) + 5H2O 2) CuSO4 (anh) -----> CuSO4 (aq) According to the Hess’s Law‚ which states that the total enthalpy change for a chemical reaction is the same disregarding

Melissa Carrithers AP Chemistry period 6 2-11-15 Determination of Ka of Weak Acids Purpose: The purpose of this lab is to find the strength of weak acids by determining the equilibrium constants for their ionization reactions in water. Is to use their measured pH values to calculate the pKa for the two unknown weak acids thus determining their identities. Hypothesis: If we neutralize a solution that contains a weak acid by adding a strong base to the solution‚ then the ions will be isolated and

Anthony Young Partner: Nick Dale TA: Alekhya 6/15/15 The SN2 Reaction: Factors Affecting SN2 Reaction. Introduction In the substitution reactions‚ the leaving group from the substrate is replaced with the nucleophile. Because of the nucleophile it is called nucleophilic substitution. The lone pair of electrons‚ present on the nucleophile is used to create a new bond with the carbon atom‚ from which the leaving group was separated. There are two different mechanisms of nucleophilic substitution: SN1
