Which explains the change in ionization energy that occurs between removing the first and second electrons from an atom?

a)the ionization energy decreases because the ratio of the protons to electrons increases.

b)the ionization energy increases because the ratio of the protons to electrons increases.

c)the ionization energy decreases because the ratio of the protons to electrons decreases.

d)the ionization energy increases because the ratio of the protons to electrons decreases.

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.
