An expression for the Ksp for hydroxyapatite would be written as follows:
Ksp =
<h3>What is
solubility constant?</h3>
In Chemistry, the solubility product constant (Ksp) can be defined as the equilibrium constant that describes a solid substance (solute) which is being dissolved in an aqueous solution.
This ultimately implies that, Ksp is typically used in chemistry to denote an equilibrium level at which a solute dissolves in an aqueous solution.
Mathematically, an expression to represent the solubility product constant (Ksp) for hydroxyapatite is written as follows:
Ksp =

Explanation:
Using the addition law of probability which states that for two events A and B, the probability that A or B will occur is the sum of their individual probabilities minus the probability that both A and B will occur. The addition rule is given by the formula:
P(A or B) = P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Let probability that a college freshman takes a math class the first semester = P(A) = 0.75
probability that a college freshman takes an English class the first semester = P(B) = 0.70
probability that a college freshman takes both a math class and an English class the first semester = P(A ∩ B) = 0.60
the probability that a college freshman takes a math class or an English class the first semester = P(A ∪ B) = P(A or B)
Therefore, P(A or B) = P(A ∪ B) = P(A) + P(B) - P(A ∩ B) = 0.75 + 0.7 - 0.6 = 0.85
P(A or B) = 0.85
Answer:
A) True, the American Federation of Labor focused on one goal-to improve working conditions in the United States. The improvement of working conditions in the United States includes collective bargaining about wages, benefits, working conditions in the workplace and representing their members in the workplace and regarding members in disputes in the workplace.
<em>The concentration, mobility, and valence state of the ionized species in a solution, as well as the temperature at which the measurement is done, all have a role. The conductivity of water increases with the concentration of ions in it.</em>
