Answer:

C

Explanation:

I'd assume it would be C because the two electrons present in the l = 2 subshell (p) are degenerate. As a result the energy needed to remove an electron in a lower subshell (l=1) would be substantially different compared to the other subshell.

The electron configuration that corresponds to the valence electrons of an element for which there is an especially large jump between the second and third ionization energies is ns^2.

The valence electron configuration of an atom refers to the arrangement of electrons on the outermost shell of the atom.

Recall that a large jump in ionization energy occurs when electrons are removed from inner shells of the atom.

If we study our options closely, we will discover that option A has only two electrons in the valence shell (ns^2).

This means that the third ionization energy involves removing electrons from an inner shell which leads to large jump.

The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that mac
KonstantinChe [14]

The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine: TRUE

<h3>What is the book value?</h3>
  • Book value is the worth of an asset based on its balance sheet account balance in accounting.
  • The value of an asset is determined by subtracting the asset's original cost from any depreciation, amortization, or impairment expenses.
  • Traditionally, a company's book value is equal to its total assets minus intangible assets and liabilities.
  • In practice, however, depending on the source of the computation, book value may include either goodwill or intangible assets, or both.
  • The value inherent in its employees, which is part of a company's intellectual capital, is always overlooked.
  • When intangible assets and goodwill are specifically omitted, the indicator is frequently defined as "tangible book value."

Therefore, the statement "the book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine" is TRUE.

How would you prepare 500 mL of 0.360 M solution of CaCl2 from<br> solid CaCl2?
LenKa [72]

We need to measure 20.0 grams of CaCl₂ to prepare 500 mL of 0.360 M solution.

First, we need to determine the required moles of CaCl₂. We have 500 mL (0.500 L) of a 0.360 M solution (0.360 moles of CaCl₂ per liter of solution).

0.500 L \times \frac{0.360mol}{L} = 0.180 mol

Then, we will convert 0.180 moles to grams using the molar mass of CaCl₂ (110.98 g/mol).

0.180 mol \times \frac{110.98g}{mol} = 20.0 g

To prepare the solution, we weigh 20.0 g of CaCl₂ and add it to a beaker with enough distilled water to dissolve it. We stir it, heat it if necessary, and when we have a solution, we transfer it to a 500 mL flask and complete it to the mark with distilled water.

We need to measure 20.0 grams of CaCl₂ to prepare 500 mL of 0.360 M solution.
