Re: KL University Model Papers

You need KL University Department of Chemistry Engineering Chemistry (11BS104) Model Question paper, here I am giving:

I. a) A Water sample has 126 ppm hardness. What is its hardness in French degree?
b) Calgon conditioning is better than Phosphate conditioning. Justify?
C) Bolt and nut made of same metal is preferred. Why?
d) What are the natures of aluminum oxide and magnesium oxide?
e) Why do all simple organic molecules not produce polymers?
f) Teflon is an additional polymer but it behaves somewhat like a thermo setting polymer. Give reason.
g) Why does Ag/Ag+ (0.1M)// Ag+ (0.1M)/ Ag constitute a cell?
h) Can we use a nickel spatula to stir a solution of copper sulphate?

i) Electrical iron poles are replaced by concrete and concrete is replaced by which material? Give 2 examples.
j) If a substance co exist in all the three phases what is that state called?

II.
a) How the following are measured with the given data? R= 8.316 joules, F= 96,500 coulombs, SOP for Zn electrode = 0.765V, SOP for copper electrode = -0.337V.

i) EMF of the cell
ii) Replacement tendency
ii) Equilibrium constant
iv) Cell reactions and net cell reaction.
v) Reaction is spontaneous or not.
b) Anode of galvanic cell is – ve and Cathode is +ve . Why?
c) How fuel cell generates voltage. Write chemical equations on involved in the process.

III
a) Large cathodic areas and small anodic areas enhance rate of Corrosion. Justify by taking 2 cases.
b) How do you protect buried pipe line from Corrosion? Suggest suitable methods?
