Chemistry Previous Year Questions

Here I have covered all the important factors which we should keep remember in mind before starting the main course.

Overview

Here I have covered Mole Formula , Relative Atomic Mass, Concentration Methods of Solute, N-factor of Different Species, Equivalence Formula, Acid_Base Titration of HCl using NaOH/Na2co3/NaHCo3.

[1] -> Theory Section: Mole Formula, Rel Atomic Mass, Limiting Reagent, Equivalence, etc. (in Hindi)

Here I have described how to deal with % strength of Oleum and 3 methods to solve any given chemical equation which are PAOC , Equivalence Method and Balancing Method.

[2] -> Theory Section: % Strength of Oleum, 3 Methods to Solve Given Chemical Reaction (in Hindi)

The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually.

[3] -> Theory Section: Hardness of Water and Volume Strength of H2O2 (in Hindi)

The one of the main tips followed by candidates for preparing for JEE Main is to practice question papers and give mock tests.
