What is the wavelength (in meters) of an electron travelling at 8.10 x 106 m s-l? Remember that 1 Joule = 1 kg m’s-?

a

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
