2ND SEMESTER EXAM. On Amaechi
Vs Jonathan
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!
