Question 1
The relative molecular mass is a number that represents how many times one _______ of a substance is heavier than 1/12th mass of Carbon (6C12)
Question 2
The Arrhenius equation gives us the relation between the temperature and the rate constant. The graph obtained by plotting temperature and rate constant is
Question 3
Which of the following act as both Bronsted acid and Bronsted Base?
Question 4
If H+ ion concentration is decreased to 10 times its initial value, its pH will
Question 5
One mole of magnesium in the vapour state absorbed 1200 
energy. If the first and second ionisation energies of Mg are 750 and 1450 
respectively, the final composition of the mixture is
energy. If the first and second ionisation energies of Mg are 750 and 1450 respectively, the final composition of the mixture is Question 6
Direction: Each of these questions contains two statements. Assertion (A) and Reason (R). Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.
Assertion (A): Neoprene can be further hardened by heating with the sulphur.
Reason (R):It contains allylic double bond which help in introducing sulphur bridges between different polymer chains.
Reason (R):It contains allylic double bond which help in introducing sulphur bridges between different polymer chains.
Question 7
The equivalent conductance of an aqueous solution of 1.0283×10-3 g equivalent acetic acid per litre is 48.15 
at 25 º C. At infinite dilution value is 390.7 
. Calculate the degree of ionisation and ionisation constant of acetic acid.
at 25 º C. At infinite dilution value is 390.7 . Calculate the degree of ionisation and ionisation constant of acetic acid. Question 8
A sample of a mixture of 
weighing 4.22 g was treated to precipitate all the Ca as 
. This 
is heated and quantitatively converted into 0.959 g of CaO. Calculate the percentage of 
in the mixture. (Atomic mass of Ca = 40, O = 16, C = 12 and Cl = 35.5)
