BELOW ARE THE TOP NOTCHED TOPICS TO EXPECT IN THIS YEAR’S POST TERTIARY SCHOOL APTITUDE TEST SCREENING,PAY RAPT ATTENTION:
The date for the Aptitude test screening has drawn closer.. It will be a bad start ,preparing for an examination, without prior knowledge of what the questions will look like or most likely topics ,upon which the questions will be drawn ,on that note the importance of this vital post cannot be over emphasized.We use this medium to urge all applicants will cover the listed topics in order to achieve a maximum grade / score in the forth coming exams, irrespective of your school.The following topics are included in the the list:
Atomic Structure and Chemical Combination
Gas laws and Kinetic Theory
Oxidation and Reduction
Chemical Equilibrium and Equilibrium constant
Solubility and Radioactivity
Empirical and Molecular formula
Percentage Composition ,mole fraction
PH and Quantum Numbers
Also take notes of questions coming from Efflorescent, Deliquescent, and Hygroscopic substance,also hard and soft water.
BELOW IS A BREAK DOWN AND CAREFUL ANALYSIS ON ALL THE TOPICS LISTED ABOVE :
Our analysis is strictly on the following criteria:
Based on repeated topics in physics ,for over ten years
It’s also based on several years of compiling aptitude test screening exercises past question
It’s based on expertise,and strictly from past question compilement
This topic is quite indispensable as questions are bound to be drawn from this topic.common areas in which questions are drawn includes these;
SepeSepara technique by :
Aspirants should be able to identify the various separation technique.
In this topic ,various questions are drawn,but the big challenge is do you know the right formula to apply in solving the questions.
Mole has several formula used in solving it,the formula to be used for a particular questions depends on the parameters given in the questions.
ATOMIC STRUCTURE AND CHEMICAL COMBINATION:
Questions are easily drawn from this topic ,and as such the following area must be touched:
How to find
Also Aspirants are expected to know these under chemical combination
GAS LAWS AND KINETIC THEORY:Applicants wishing to win Scholarships can click here to apply for MTN FOUNDATION SCHOLARSHIP
Gas laws are basics and hence aspirants are expected to know the basic laws of gas laws, and Kinetic theory as well.the area covered in this topic includes;
Ideal gas law
General gas equation
Graham’s law of diffusion
PERIODIC TABLE AND ELECTRONIC CONFIGURATIONS:All Aspirants can now view PHYSICS AREA OF CONCENTRATION HERE
Here,aspirants are expected to know these;
Group(s) in which an element belongs
Period in which an element belongs
Some basic properties which includes..
Periodicity of an element
OXIDATION NUMBER AND REDUCTION:
This topic is very important and common as well,in that questions are easily drawn from,hence Candidates should be prepared and weary about this topic.On ascertaining which element is oxidized or reduced ,basic rules and principle govern it,hence applicants are expected to know it.
Also in assigning oxidation numbers to elements ,basic laws govern it,and must be adhered to.Click here to view your WAEC RESULT
RULES GOVERNING THE ASSIGNING OF OXIDATION RULE INCLUDES THIS;
The oxidation number of a neutral compound or element is zero
The oxidation number of a simple ion is equal to the charge on that ion
The oxidation number of a polyatomic ion is equal to the charge of that ion
The oxidation number of oxygen is minus two ( -2 ) except in peroxides,where it’s minus one(-1) E.G H2O2
The oxidation number of hydrogen is plus one (+1) except in hydride where it’s minus one (-1) e.g NAH
The oxidation number of a neutral compound is zero
CHEMICAL EQUILIBRIUM AND EQUILIBRIUM CONSTANTS:
in this topic ,candidates are expected to know how to :
Solve Equilibrium constant
Know the effects of these on equilibrium position ;
Effect of temperature
Effects of catalyst
RADIOACTIVITY AND SOLUBILITY:
In this topics ,all aspirants are expected to cover this:Also if you want to make money even as a student,click here to view TOP LUCRATIVE BUSINESSES YOU CAN DO AS A STUDENT
How to solve half life questions
How to find decay constants
Applicants should know basic definition of Radioactivity
Applicants should also know ,how to solve solubility product related questions.
EMPIRICAL AND MOLECULAR FORMULAS:
The basic tin here is to know the how to solve empirical formula of any compound and Molecular formula as well and the relationship between them as well.
PERCENTAGE COMPOSITION AND MOLE FRACTIONS:
In this topic ,applicants are expected to know how to solve percentage Composition and know mole fraction
PH & POH AND QUANTUM NUMBERS;
Here basic definition ,calculation involving PH and POH should be known by applicants,also these should be known in quantum numbers:
Principal quantum Number
Azumuthal quantum numbers
Magneticquantum Number and Spin quantum number
STOICHIOMETRY AND ORGANIC CHEMISTRY;
In this topic,rapt attention should be paid to these:
How to solve mass to mass questions
No of moles ratios question
Mass to volume questions
Also applicants must know how to name organic compound
How to identify the correct structures of organic compound
We sincerely wish all applicants success in advance.
