2ND SEMESTER EXAM. On Amechi Vs Jonathan

Course tittle: CHM 215 (THERMODYNAMICS ≠ OF POLICTICAL CHEMISTRY)
TIME ALLOWED: 72 Hours.
QUESTION 1.
In a reaction involving 19g of Amaechium sulphate and 16g of Jangline carbonate, 2015g of Forumium Governo 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 Akpabio Chloride was added using Goodluckium solution, calculate the mass of Amaechium sulphate that would have been needed for the reaction to be endothermic?
iii. What is the colour of Akpabio Chloride before and after the 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.
v. Using their age, prove that Jangline is weak and would need more solution of Goodluckium nitrate to be able to precipitate Amaechium from the reaction.
vi. Why is it that the solution produced can't react with APCium Nitrate but would react violently with Turkia PDP (5) Jonite?
Goodluck to you!
