Chemistry Exam (CHEM 419)
(THERMODYNAMICS OF POLICTICAL CHEMISTRY)
TIME ALLOWED: 72 Hours.
QUESTION
1. In a reaction involving 72g of Buharium sulphate and 53g of Janatine carbonate, 2015g of
presidium electorate acid was produced.
i. Calculate the percentage purity of the product,and assuming the reaction took place under
Jega standard condition.
ii. Assuming that 3g of Ma'azuim Chloride was added using Goodluckium solution, calculate
the mass of Buharium 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 electrochemicalseries 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 Buharium from the reaction.
vi. Why is it that the solution of RIGium produced can't react with APCium Nitrate but would
react violently under PDPium Jonite acid?


NB : Use of Four Rigging Table is not allowed in the exam Hall



Your time starts now!

Op, you forgot to ask if the reaction is exothermic or endothermic; and the amount of heat absorbed or given during the reaction.

Dats ll b a bonus point for you

I hope the admins will see this and move it to the front page for pple to learn.

Say no to exothermic elections,
reduce the activation energy,
Say no to increased political entropy.

Wish all Nigerians a peaceful elections.
