THERMODYNAMICS OF POLITICAL CHEMISTRY (CHEM 411) 2ND SEMESTER EXAM. TIME ALLOWED: 72 Hours. QUESTION 1. In a reaction involving 70g of KWANKWASONIUM sulphate and 53g of Janatine carbonate, 2015g of presidium electorate acid was produced. i. Calculate the percentage purity of the product, assuming the reaction took place under JEGA standard condition. ii. Assuming that 3g of Maazuim Chloride was added using Goodluckium solution, calculate the mass of KWANKWASONIUM sulphate that would have been needed for the reaction to be WINothermic? iii. What is the colour of Goodluckium Chloride before and after free and fair reaction? iv. Calculate the molecular weight of the reactants and products with respect to their places on the electrochemical series of quality leadership and state which is stronger and why. v. Using their molecular numbers, prove that Jonatine Chloride is weak and would need more INECium solution from JEGAnium nitrate to be able to precipitate KWANKWASONIUM from the reaction. vi. Why is it that the solution of RIGium produced cant react with APCium Nitrate but would react violently under PDP Jonite acid? Use of Four Rigging Table is not allowed in the exam hall. Goodluck to you!
