QUIZLET Set A contains 52 elements and Set B contains 46 elements. If Sets A and B have 29 elements in common, what is the total number of elements in either Set A or Set B.

69

Explanation:

Set A = 52 elements, set B = 46 elements, A intersection B = 29 elements.

A only = 52 - 29 = 23

B only = 46 - 29 = 17

Total number of elements in either set A or set B = number of elements in A only + number of elements in B only + number of elements in A intersection B

                    = 23 + 17 + 29

                         = 69 elements

Hence, the total number of elements in either Set A or Set B is 69

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

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
