why carbon always form covalent bond?
 
 
The carbon atom needs to either gain or lose 4 electrons to complete its valence shell. But it is difficult for it to lose 4 electrons as it would require about 6200 joules of energy and for...

A carbon atom is tetravalent .it has 4valence electrons .it cannot gain electrons as it could lead to low stability as the nuclear charge cannot outweigh the net charge.because of similar...

WHY ARE COVALENT COMPOUNDS POOR CONDUCTORS?
 
 
COVALENT COMPOUNDS POOR CONDUCTORS because they do not contain any ions in solution state. The conductivity is due presence of ions in solution/ molten state. But covelent compounds do not...

if the solubility product of BaSO 4 is 1.5*10 -10 in water. It’s solubility , in moles per litre is
 
 
BaSO4 ionises to give – BaSO4 Ba 2+ + SO 4 2-- Suppose solubility of BaSO4 is s mol/l.It would give s mol/l of Ba2+ ions and s mol/l of SO4 2- ions on dissociation. Now, solubility...

THE QUESTION IS ABOUT INTERFACIAL AND SURFACE TENSION It is given that surface tension is the net downward pull or force if liquid (water) is taken but if two immiscible liquid is taken then...
 
 
At liquid-air interfaces, surface tension results from the greater attraction of water molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion). The net...
