Dipole moment of HC1 = 1.03 D, HI = 0.38 D. Bond length of HC1 = 1.3 and HI = 1.6A .The ratio of fraction of an electric charge, δ, existing on each atom in HC1 and HI is
If the bond length and dipole moment of a diatomic molecule are 1.25 A and 1.0D respectively,what is the percent ionic character of the bond
The molar ionic conductivities of NH4+ and OH- at infinite dilution are 72 and 198 ohm-1cm2mol-1 respectively.The molar conductance of a centinormal NH4OH solution at the same temperature is found to be 9 ohm-1cm2mol-1,The percentage dissociation of NH4OH at this concentration will be
One mole of A and 2 moles of B are allowed to react in a one lit flask. What is the value of Kc if at equilibrium,0.4 moles of C is formed in the reaction A+2B⇔C+2D
H3O++OH-→2H2O
The solubility of AgCl in NaCl solution is less than that in pure water,because
The equilibrium constant for the reaction H2(g)+I2(g)⇔2HI(g) is 81 at a certain temperature.If the concentrations of H2 and I2 are 3mole.lit each at equilibrium,the equilibrium concentration of HI is
consider the following reaction equilibrium N2(g)+3H2(g)⇔2NH3(g).Initially 1 mole of N2 and 3 moles of H2 are taken in a 2 litre flask.At equilibrium state if the number of moles of N2 is 0.6 what is the total number moles of all gases present in the flask at equilibrium
On passing a current through molten KCl 19.5g of K is deposited.The amount of aluminium deposited by the same quantity of electricity if passed through molten AlCl3 is
A quantity of PCl5(g) was heated in a 10 litre vessel at 2500C PCl5(g) ⇔PCl3(g)+Cl2(g) At equilibrium the vessel contains 0.1 mole of PCl5 0.2 mole of PCl3 and 0.2 mole of Cl2 .The equilibrium constant is
