Which of the following statements about molecules is false? O They can be represented by an electron-dot diagram
O They are not useful to humans
O They contain two or more atoms
O They are the smallest particles of a covalent compound

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
