    A saturated solution is a solution in which no more solute can be dissolved at a given temparature.
    Example; If we add sugar continuosly and stirr it it dissolves but one stage will come where no more sugar can be dissolved this is known as saturated solution.

    It is the ratio of conc. of products to the conc. of reactants with each conc.term raise to the power equal to the stiochiometry of balance chemical equation Qc = [C]^c ×[D]^d -------------------- [A]^a×[B]^b At the time of equilibrium Qc is equal to Kc

    The electronic structure of nitrogen atom is  Leaving out 4 electrons in the 1s orbital of two nitrogen atoms constituting the molecule (represented as KK), the molecular orbital energy diagram for remaining 10 electrons in nitrogen (N2) is as shown as below:


    (i) Electronic configuration:
    N2 : [KK (σ2s)2 (σ2s)2 (2px)1(σ2pz)2]
    (i) Bond order : Here Nh = 8 and Na = 2

    The two nitrogen atoms in nitrogen molecule are linked by three covalent bonds (i.e. a triple bond).

    It is shown that the antiaromatic compound is more stable than the non aromatic compounds 2 and 3 because of a more conjugated system. Here's the exact statement: In the first structure, delocalization of the positive charge and the π bonds occurs over the entire ring.

    The negative electron gain enthalpy is more in sulphur than in oxygen because, both of them are in 16th group in which teh oxygen is 1st element which has the minimum size and sulphur has larger size due to addition of a new shell. So, due to smaller size the inter-electronic repulsion in compact 2p-orbitals of oxygen is much more than the repulsion in 3p-orbitals of sulphur hence, the incoming new electron feels less attraction in oxygen and more attraction in sulphur due to which the addition becomes easy and so electron gain enthalpy becomes more negative in sulphur.

    Gaurav can you explain the concept of non stoichiometery here.

    2Thank You

    Gaurav Seth 6 years, 10 months ago

    ‘Non-stoichiometric’ are those hydrides in which the ratio of the metal to hydrogen is fractional. This fractional ratio is not fixed but varies with temperature and pressure. Many of the d-block elements and f-block elements (lanthanoids and actinoids) react with hydrogen at elevated temperature to give metallic or non-stoichiometric hydrides. For example LaH2.87, TiH1.8.,Zr H1.9, VH1.6 etc. Since in these hydrides, hydrogen is present in the interstices (holes or voids) existing in between the atoms, therefore these hydrides are also called interstitial hydrides.

    2Thank You

    Kriti Sharma 6 years, 10 months ago

    It is really very easy trust me interstial hydrides are formed by d and f block elements.in d block group 3,4,5,10,11,12forms these hydrides .group 6,7,8,9 is called hydride gap.these are called interstial as hydrogen atom may occupy may occupy interstial sites in these lattices .hope this helped you.
