Zeolites - 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 aluminosilicat..

. 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..

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 + 5 2x - y = 5 (1) When x is diminished by 4, fraction..
