Zeolites are microporous aluminosilicates of general formula M x / n [AlO 2 ] x [SiO 2 ].mH 2 O and may be considered as open structures of silica in which aluminium has been substituted in a fraction x / (x+y) of the tetrahedral sites. The negative charge of the aluminosilicate framework..

. This gives In the temperature range in which resistivity increases linearly with temperature, the temperature coefficient of resistivity a is defined as the fractional increase in resistivity per unit increase in temperature. Ohm's law is obeyed by many substances, but it is n..

. When the rate of adsorption equals the rate of desorption, dynamic equilibrium is attained. If q is the fraction of the total available surface covered with gas molecules, at any instant, then (1- q ) is the fraction of the surface of the solid which is empty. From kinetic the..

It is the fraction of the total number of molecules, which dissociate into simpler ions i.e.,..

D m = {zm p + {A-Z}m n - m N } Total B.E = ( D m) C 2 = [zm p + ((A-Z)m n ) - m N ]c 2 Average B.E per nucleon Natural radioactivity is the phenomenon of emission of active radiations by heavy nuclei, on their own, without any external provocation. The three types of radi..

Find the fraction which becomes when the denominator is increased by 5 and is equal to when the numerator is diminished by 4. Let the fraction by When y is increased by 5, fraction becomes or 2x = y +..
