What is the chemical formula for hard water?
In polar covalent molecule, one atom gets positive charge and the other one takes negative charge as known as dipole.
The rate constant for a reaction of Zero order in A is 0.0030 mol L¯¹ s¯¹. How long will it take for the initial concentration of A to fall from 0.10 M to 0.075 M?
Favourable conditions for electrovalency are: (1) Low charge on ions, large cation, small anion (2) High charge on ions, small cation, large anion (3)High charge on ions,
Here''s the equation: NaOH + H2SO4 = Na2SO4 + H2O
Why a covalent bond is directional? Covalent bond is formed as a result of pairing of two electrons in atomic orbitals of two atoms. Bond then must lie along the direction of
