Can you think of another experiment that can manifest a random variable???​

i'm assuming that the correct answer is indeed the first one/ "a"..

i think its 5049.

i hope this !

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
