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 “.
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 structure. Here it have only two hydroxyl groups that is -OH groups, and the hydrogen atoms joined to these only are ionisable. So only these
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 applied magnetic field. This property is shown by the atom, ions or the molecules that contain unpaired electrons. 2. Ferromagnetism:- This is the phenomenon by
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
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
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
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
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 various kind of bonding that we see around us. Covalent bond A covalent bond is formed by mutual sharing of electrons between two atoms. For
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
