HOW TO SOLVE NUMERICAL PROBLEMS IN CHEMISTRY OR PHYSICS 



In this post we will see how to solve numericals problems in chemistry or physics?

This video will explain you in detail that how to solve numericals problems in chemistry or physics.

This video will teach you about how to solve numericals problems in chemistry 

This video also teaches you about how to solve numericals problems in physics 

How to solve numericals problems?

Step 1 : Learn the formula.
Step 2 : Learn the concept of formula.
For example 
this formula is of 11th std of chemistry 
PV=nRT 
In this formula Learn about that in this formula 
What is P?
What is V?
What is n?
What is R? 
What is T 
Here 
P is the pressure 
V is the volume 
n is the number of mole 
R is the gas constant 
T is the temperature 
Step 3: Do the easy solved examples given in the textbook or any book which you prefer.
If you can not solve the given problem by own then clear your concept again and Learn the formula.
If you have solved the problem by your own then move to step 4. 
Step 4: Do the hard solved examples given in the
Textbook or given in the book that you refer. 
If you can't solve the problem than go to concept and clear you concept properly. 
If you can solve the problem then go to step 5 
Step 5: Do the easy numericals given in the exercise.
If you can't solve that problem then Clear you doubt with your teachers. 
If you can solve the problem then go to step 6.
Step 6: Solve the hard numericals given in the exercise.
If you can solve the hard numericals from exercise then you can also solve the moderate level exercise from textbook.

PERIODIC TABLE

 Modern Periodic table Modern Periodic Law :  The recent work has established that the fundamental property of an atom is atomic number and not atomic weight. Therefore, atomic number is taken as the basis of the classification of the elements. The modern periodic law was given by Moseley, it may be stated as : ''The properties of elements are periodic functions of their atomic number". Modern periodic table is also called long form of the periodic table or Bohr’s table. In this table, the elements are arranged in order of their increasing atomic number. It consists of 4 blocks (s, p, d and f), 18 groups numbered from 1 to 18 and 7 periods numbered from 1 to 7. Short tricks to learn periodic table  Blocks : The periodic table is divided into four main blocks (s, p, d and f) depending upon the subshell to which the valence electron enters into.  (1) Elements of group 1 and 2 constitute s-Block.   (2) Elements of group 13, 14, 15, 16, 17, 18 constitut...

COMPOUNDS OF ALKALI METALS

 COMPOUNDS OF ALKALI METALS  1. Sodium (Na) , Natrium  Extraction of sodium  : Down's Process  By Electrolysis of fused NaCl + CaCl 2 + NaF  At cathode (Iron Vessel) : Na+ +e– ⟶  Na(s)  At Anode (Graphite) : 2Cl–   →    Cl 2 + 2e–  (i) (CaCl 2 + NaF) is used to lower Melting point (8000 C) of NaCl to about 6000 C.  (ii) Aqueous sodium chloride cannot be used for preparing sodium by electrolysis. Because instead of metallic sodium, hydrogen gas will be liberated at cathode. Properties sodium , Natrium (i) sodium is a crystalline soft metal.  (ii) Highly reactive, so kept in kerosene.  (iii) Na dissolves in liquid NH3 to give blue solution.  Uses of sodium , natrium  (i) In the preparation of sodium amalgam (used as reducing agent)  (ii) In sodium vapour lamp, which emits monochromatic yellow light.  (iii) As heat transfer medium in nuclear reactors. 2.

Mastering Name Reactions in Organic Chemistry: A Complete Guide for Class 11, 12, NEET & JEE Aspirants

Mastering Name Reactions in Organic Chemistry: A Complete Guide for Class 11, 12, NEET & JEE Aspirants Organic chemistry forms the backbone of competitive exams like NEET, JEE Main, and JEE Advanced, contributing approximately 30-40% of the total chemistry questions. Among various topics,  name reactions  stand out as high-yield, frequently tested concepts that can single-handedly secure 15-20 marks in board exams and 4-5 questions in competitive exams. This comprehensive guide explores the most important name reactions, their mechanisms, strategic learning approaches, and exam-oriented tips to help you excel in Class 11, Class 12 boards, NEET, and JEE examinations. ​ What Are Name Reactions? Name reactions are chemical transformations named after their discoverers or developers who made significant contributions to organic chemistry. These reactions represent simplifications that avoid lengthy descriptions of complex chemical transformations. Rather than memorizing abstra...
