    Thanku ma'am for answer but I was a little examining what everybody knows.actually simple diefination of equilibrium is that any thing constant with time is said to be in equilibruim yes its a different matter that it is further divided but as far as I think this is the simple one

    equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

    Exactly any system in the nature doesnt use its all energy to do any useful work actually it frees that much energy only that the task or work would be complete so the defination is the amount of energy that is free by the system to do maximun useful work is called gibbs free energy

    this is because they have lesser electrons, while their nuclear charge remains the same. The remaining electrons are, therefore held more tightly by the protons in the nucleus and thus their radii.are smaller than the parent atoms andParent atom has more electrons so the effective nuclear charge on each electron is less. Now when a cation is formed electron(s) is/are lost. So the effective nuclear charge or simply put, the attraction of the nucleus towards the electrons increases. So due to greater pull, the nucleus pulls the shells towards it.. there by reducing the size.

    Carbon monoxide (CO) is considered to be more toxic or hazardous than Carbon Dioxide (CO2) due to the fact that CO reacts with the hemoglobin in our blood streams and produces a stable compound that actually prevents oxygen from entering the body. However, CO2 is more tolerable in a human body because we are able to exhale it. And it doesn't have the same chemical properties that CO has. CO2 doesn't react with the hemoglobin in our blood streams. To be more specific there is a reaction between CO and the hemoglobin in our body that occurs while on the other hand the CO2 doesn't. Basically, the hemoglobin is an oxygen binding protein, and CO is more ready to share it's oxygen atom with the hemoglobin than the CO2. read less

    So the halogen decides the ionic and the covalent character. Since flourine has smaller size than chlorine so it does not polarises the bond but chlorine has larger size, it polarises the bond. And we know that as polarity increases in a compund, its covalent character increases.

    The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability. As the dielectric constant increases, the electric flux density increases, if all other factors remain unchanged.

    A peroxide is any compound which has two oxygen atoms bonded together. The O-O group is the peroxide group of the compound. And Hydrogen Peroxide is the simplest peroxide. The chemical formula for hydrogen peroxide is H2O2. It is a water molecule with one extra atom of oxygen,.

    Properties of Hydrogen Peroxide

    • Hydrogen Peroxide is an almost clear, pale blue liquid in its pure state
    • It has an odour similar to that of nitric acid
    • Hydrogen peroxide has a viscosity higher than water. It is about 40% denser than water
    • It is acidic in nature.

    Heavy water or deuterium oxide (D2O) is a form of water that contains a large amount of the hydrogen isotope deuterium which is also known as heavy hydrogen.
    1)It is colourless, odourless and tasteless mobile liquid heavier than water. Because of higher molecular mass there is a marked difference in physical properties of ordinary water and heavy water.
    2)Dielectric constant of heavy water is lower than that of ordinary water therefore ionic compounds are less soluble in heavy water than in ordinary water.
