The boiling point of Cl2 is -35°C and the boiling point of C2H5Cl is +13°C. These molecules are isoelectronic, so why are the boiling points different?

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

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
