For a general reaction such as:
The equilibrium constant is
where the terms [A], [B],...strictly represent activities but are frequently approximated as concentrations or partial pressures. (This assumes ideal thermodynamic behavior and is a much better approximation for gases than in solution.)
For the formation of covalent bond, the difference in the value of electron egativities should be: (1) Equal to or less than 1.7 (2) More than 1.7 (3) 1.7 or mor

interpretation ande of errors in differential thermal analysis
Aromaticity or aromatic character The characteristic behaviour of aromatic compounds is termed as aromaticity. Aromaticity is due to the extensive delocalisation of p-electron
A covalent bond is likely to be formed between two elements which: (1) Have similar electronegativities (2) Have low ionization energies (3) Have low melting points (4
Properties of Gases Gases are easily expandable ,compressible unlike solids and liquids. Gases are measurured in pressure.Pressure is defined as force exerted per unit area of
does adding hcl to acetic acid and sodium acetate = more acid consumption r spodium consupmtion?>
How many ion H2- does have The H2- ion having three electrons. This can be conceived as the combination of a hydrogen atom with a hydride ion (H-). By the aufbau principle, two
Since fluorine is very electronegative as a result hydrogen develop a very positive character. As a result the H-bonding is very tough because of large difference in electronega
I read that in the first transition series,the stability of +2 oxidation state decreases from Sc to Cu.but,I observed that as we move along the 3d -series,the stability increases i
