Use the diagram to answer each question. Explain how researchers might have obtained the data shown in the table

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

the answer is 75.0%.

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
