Actually the word co-ligative itself reveals that (“co” means each other and “ligative” means related) These are the properties which are related to each other. The colligative properties are those properties that depend on the number of solute particles in a solution or a mixture. “These properties don’t depend upon the nature of particles “. Following are the colligative properties:- […]
Meaning of diprotic acid is that , it can loose two hydronium ions (H+) . For finding how many H+ ions it can give , we have to see its […]
The structure of XeOF4 is square pyramidal. And its hybridization is sp³d² The structure of XeO3 is pyramidal and its hybridization is sp³.
It is the number of lattice points touching one lattice point in a crystalline solid. For example in case of Sodium chloride it is 6 .
1. Paramagnetism :- This is the phenomenon by which substances are weekly attracted by the magnetic field. It arises because the substances are magnetized in the same direction of the […]
These are the elements that can act as a base as well as an acid. If they react with an acid , they behave as a base . And if they react with a base they behave as an acid . Oxides of aluminum and gallium are amphoteric in nature.
What are the characteristics of a lone pair? Characteristics of a lone pair Lone pair are the pair of electrons that do not take part in any chemical bond. They affect the symmetry of molecule or the shape of molecule as they interfere with the other electrons of the molecule . The electrons of lone pair repel the other bond […]
What are azetopes? Azeotropes are the constent boiling mixtures or solutions. it means that these mixtures can not be separated by simple distillation or boiling , because they will have the same composition of mixture even in the vapour state. for example as in case of mixture of nitric acid and water, the highest attained concentration of the nitric acid […]
Br2 is a homoatomic molecule, a molecule with same kind of atoms. So here the electronegativity of both the atoms is same so the shared pair is equally attracted by the two atoms. There is not a chance of transfer of electrons from one atom to another. And thus they go for sharing of electrons only to satisfy their valencies. […]
This is a best example to share when we talk about chemical change, that the products have totally different properties from that of the reactants , from which they are made. Now coming to the answer, Formation of water is a highly exothermic type of reaction and a lot of energy is lost at the time of reaction and the […]
Chemical bond may be defined as the force of attraction by which two atoms are held together. The chemical bonds lead to the formation of molecules and crystals. There are […]
Atomic mass Atomic mass of an element is the relative mass as compared with an atom of carbon 12 and it is expressed in AMU. A.M.U. AMU is the Atomic mass unit and it is defined as the mass equal to 1 by 12th of the mass of carbon 12 isotope. 1 amu = 1.66056x 10-24 Molecular mass It is […]
