Standard temperature and pressure (stp), in the context of gases, refers to

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

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
