This post will contain the topics with explanation which are a part of MCAT syllabus but are not covered in FSc books.

Inertness Of Nitrogen:
                                    Molecular nitrogen is inert under ordinary conditions existing as diatomic nitrogen N2. The presence of a very strong triple covalent bond renders it nonreactive under normal circumstances. Nevertheless nitrogen does react with alkali metal lithium to form a compound Li3N, even under ordinary conditions.
Under high temperature and pressure and with right catalyst nitrogen becomes more reactive. Haber's process uses such conditions to form ammonia. Inert atmosphere consisting of gases such as argon , nitrogen or helium are commonly used in chemical reaction chambers and in storage containers for water and air sensitive substances to prevent any side reaction.

NUMS

National University of Medical Sciences (NUMS) Constituent Colleges: The existing medical colleges of the armed forces would come under the umbrella of this university i.e. Army Medical College (AMC) Rawalpindi Quetta Institute of Medical Sciences CMH Lahore Medical College  will be under NUMS and these will follow one standard course format. Why NUMS? One of the reasons to establish NUMS is to increase the intake of the army cadets.  NUMS Entry Test: Entry Test for above mentioned colleges will be conducted once a year. The test will be conducted in October - November. Those students who wish to apply on civilian seats or as paying cadets will have to appear in this test. Pattern of the Test: Biology 20 MCQs Chemistry 20 MCQs Physics 20 MCQs English 20 MCQs Intelligence 20 MCQs Total MCQs = 100. Time allowed to solve the test will be 2 hours. The Good thing is there will be no negative marking in the test. The type of the questions will be the same as they used to be in Nust ...

Inverse of a Function

Inverse of a Function In this Post I will discuss the method for finding the inverse of a given function from the 4 options as given in the Entrance tests of Engineering Universities. The very first step before finding the inverse is to make a check whether the function is One-to-One or not.  By One-to-One function we mean that function for example f(x) should not have the same value at two different values of x. In other words for each element of the Domain there should be a distinct element in the range. Check for One-to-One: A function which passes the horizontal line test is a One-to-One function. This means if a horizontal line is drawn it should not cross the function curve at more than one point. Another way to check if a function is One-to-One or not is shown below: If , f(a) = f(b) , implies that a=b , the given function is One-to-One. Consider the following examples: f(x) = 5x + 10 f(a) = 5a + 10 f(b) = 5b + 10 Taking f(a) = f(b) gives, 5a...
