comparative properties

A detailed comparison of properties of metals and non-metals is given in table. Property Metals Non-metals State of matter These are usually solid, except mercury, which is a liquid at room temperature. Gallium and Caesium melt below 30 . So if room temperature..

In colloidal systems the number of colloidal particles per litre of the sol is relatively much smaller than solute particles in a true solution. Colloidal particles are aggregates of simple molecules and colligative properties such elevation in boiling point, depression in freezing point ..

Physical Properties - Being polar in nature, the acid derivatives have higher boiling points than hydrocarbons of comparable molecular masses. Acid chlorides, anhydrides and esters have nearly the same boiling points as the aldehydes and ketones of comparable molecular..

Physical Properties of Water - Pure water is transparent, tasteless, colourless and odourless. It readily picks up the flavour of any substance dissolved in it. Water in thick layers appears greenish blue. Due to the presence of intermolecular hydrogen bonding in H 2 O molecules, the free..

>. Moreover, since ionization energies of O 2 and xenon are comparable he thought that an analogous reaction should be possible with xenon. He tried the reaction between Xe and PtF 6 by direct interaction and synthesized the first compound of noble gases Xe + [PtF 6 ] - in the form of red..

Pure water is transparent, tasteless, colourless and odourless. It readily picks up the flavour of any substance dissolved in it. Water in thick layers appears greenish blue. Due to the presence of intermolecular hydrogen bonding in H 2 O molecules, the freezing point, boiling point, heat of f..

They are not deflected by electric and magnetic fields. They affect photographic plates. The ionising power is very low compared to alpha-particles and beta-particles. They are electromagnetic waves like X-rays and light rays. The wavelength of these rays are shorter than that ..

Properties of Gases in Terms of Molecular Motion - Gases, as well as mixture of gases, behave as seen above, with regard to changes in temperature, pressure or both. The following assumptions can be made on the basis of the kinetic theory of gases: A molecule of a gas means the smallest u..

Colligative Properties - Depression in Freezing Point - Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of the substance has same vapor pre..

The structure of a nitro group can be represented as a resonance hybrid of two equivalent zwitter ionic polar structure..
