effects of hydrogen bond of density of water

Alkaline Earth metals are denser and harder than the alkali metals of group. 1. The comparatively smaller atomic size of alkaline Earth metals leads to more closely packed crystal lattices and hence stronger metallic bonds. This accounts for their increased hardness and high density..

It is a common observation that density of ice is less than that of water because of which ice always floats over water. Moreover, it is a known fact that density of water is maximum at 4 o ..

>As a result of tetrahedral arrangement of H 2 O molecules in the solid state, the ice structure extends in three dimensions. Further the molecules of H 2 O are not packed closely as hydrogen bonds between oxygen and ..

Density - 0.5 kg of cotton occupies more space than 0.5 kg of iron. The particles of iron are closely packed while that of cotton are loosely packed. The amount of iron packed in a unit volume is more. This explains as to why iron is heavier than the same volume of cotton. In Physics, we ..

The SI unit of density is kg m - 3 and in the cgs system, the unit of density is g cm -3 . The densities of different substances vary widely. Densities of most of the solids are greater than that of liquids, though there are exceptions. Densities of..

Hydrogen bonding has important effect on many physical properties of compounds, described bel..

This bond is formed between the hydrogen atom and an atom of the electronegative element (F,O,N) , of the same molecule . Intramolecular hydrogen bond results in the cyclization of the molecules and prevents their association. Consequently, the ..

Since hydrogen bond comes into existence as a result of dipole-dipole interactions between the molecules, therefore, following conditions are required for effective hydrogen bonding. (i) Hydrogen atom should be bonded to a highly..

. This may be represented as: The hydrogen atom acts as a bridge between two atoms, holding one atom by a covalent bond and the other atom by a hydrogen bond. The hydrogen bond is represented by dotted line (....) while the covalent b..

Nitrogen in its compounds with hydrogen shows hydrogen bonding though to a lesser extent than oxygen. For example, ammonia (NH 3 ) shows intermolecular hydrogen bonding...
