versailles essays
versailles essays The Treaty of Versailles, which was a peace treaty that called for the end of World War 1(between Germany and the Allies), was defeated in the Senate by an unknown alliance of two forces. The two forces were President Wilsons all or nothing attitude and the strong opponents of the Treaty in the Senate. William Borah (Sen, Idaho), one of the irreconcilables, brings out a clear weakness in the Covenant of the League of Nations in his speech to the Senate. The weakness is that will any country really feel comfortable, or approve of, another countrys government dealing with their domestic affairs and concerns, especially if they have an army to support whatever they decide. He also brings up a point that no one would approve of a tribunal, with 41 other nations in it, to settle a problem that might arise between members of the nation because what one nation sees a vital, another nation may see as wasteful, which might just lead to another World War. The League as he describes it is contradictorial in all that it is to accomplish (force to destroy force, conflict to prevent conflict, militarism to destroy militarism, war to prevent war) and it cant work like that because it has no authority to back up its own judgment. This goes against Wilsons idea of the League because he helped create it and it is a very important and big step to him in creating a worldwide government (Doc A) The Treaty as portrayed in The New Republic is useless, which is a strong reason it shouldnt be passed. It wasnt useless in the sense that it would officially end the war, but in a sense that it would not moralize nationalism. The moralization of nationalism could be achieved by ending the separation of classes and ambitions that could only be enjoyed by some, not all, people in the country. According to the journalist the Treaty d...

Concentration and Molarity Worked Example Problem
Concentration and Molarity Worked Example Problem Question a) Explain how to prepare 25 liters of a 0.10 M BaCl2 solution, starting with solid BaCl2.b) Specify the volume of the solution in (a) needed to get 0.020 mol of BaCl2. Solution Part a): Molarity is an expression of the moles of solute per liter of solution, which can be written: molarity (M) moles solute / liters solution Solve this equation for moles solute: moles solute molarity Ãâ" liters solution Enter the values for this problem: moles BaCl2 0.10 mol/liter times 25 litermoles BaCl2 2.5 mol To determine how many grams of BaCl2 are needed, calculate the weight per mole. Look up the atomic masses for the elements in BaCl2 from the Periodic Table. The atomic masses are found to be: Ba 137Cl 35.5 Using these values: 1 mol BaCl2 weighs 137 g 2(35.5 g) 208 g So the mass of BaCl2 in 2.5 mol is: mass of 2.5 moles of BaCl2 2.5 mol Ãâ" 208 g / 1 molmass of 2.5 moles of BaCl2 520 g To make the solution, weigh out 520 g of BaCl2 and add water to get 25 liters. Part b): Rearrange the equation for molarity to get: liters of solution moles solute / molarity In this case: liters solution moles BaCl2 / molarity BaCl2liters solution 0.020 mol / 0.10 mol/literliters solution 0.20 liter or 200 cm3 Answer Part a). Weigh out 520 g of BaCl2. Stir in sufficient water to give a final volume of 25 liters. Part b). 0.20 liter or 200 cm3
