Q. The equilibrium cell potential of the galvanic cell
is found to be Ecell,eq = 1.410 V at 298.15K. The standard cell potential is Ecell,eq = 1.360V.
(a) Write the cell reaction and calculate its thermodynamic equilibrium constant at 298.15K.
(b) Use the cell measurement to calculate the mean ionic activity coefficient of aqueous HCl at 298.15K and a molality of 0.500 mol kg-1.
Alkali metals belong to S-block ? why?
Benzaldehyde - Aldehydes and Ketones Benzaldehyde is simple aromatic aldehyde. It occurs in bitter almonds in the type of its glucoside, amygdalin (C 20 H 27 O 11 N). While amy
Calculate the ratio of d number of molecules in two energy levels at 27''c given E2=9.75x10"-13erg/mol E1=6.95X10"-13erg/mol g1=2 g2=3
10 g of h2 and 64 g of o2 are filled in a steel vessel and exploded amount of water produced in this reaction
Substitution reactions Replacement of a molecule or set/group of the substrate by any another type of atom or group is termed as substitution reactions. Examples :
#sulphuric acid can be made with concentration of 99%.however for diferent industrial requirement ,62% h2so4 is used which has density of 1.55 g/ml.calculate the molarity,molality
If 8686 C of charge is passed through molten magnesium chloride, calculate the number of moles of Mg(l) produced
USE THE KINETIC PARTICLE THEORY TO EXPLAIN THE EXISTENCE OF THE DIFFERENT STATES OF MATTER
