A) Cl- ion

B) These energies are equal for all forms of the same element

Explanation:

The ionization energy for a chlorine atom is equal in magnitude to the electron affinity of Cl⁻ ion because these energies are equal for all forms of the same element.

  • Electron affinity is the energy released  in adding an electron to  a neutral atom in the gas phase.
  • Ionization energy is the amount of energy required for the removal of an electron in atom or ion.
  • Here the energy released when an electron is added to the Cl atom(electron affinity) to form a chlorine ion is the same energy that would be required to remove the added electron from the ion to form an atom(electronegativity).
  • Here we find out that both energies are the same for the atom of Cl that is gaining electron and for the ion in which electron is being removed.

What is the percentage error of length measurement of 0.229cm if the correct value is 0.225cm
Mars2501 [29]

Percent error is the difference between the measured and known value, divided by the known value, multiplied by 100%.

So first, we take our measured value, .299 cm, minus our known value, .225 cm.

.299 cm - .225 cm=.004 cm

Next, we divide that by our known value

\frac{.004}{.225}=.0177777778

Finally, multiply your answer by 100

.0177777778 x 100= 1.77777778 %

Round to three significant figures, and you're done.

=1.78 % error

2.what is the purpose of the sodium sulfate? (1 pt) why did you rinse the sodium sulfate with an additional portion of methylene
suter [353]

To ensure that the 9-Fluorenone was totally dry, it had to be washed with methylene chloride. To make sure that methylene chloride is present in a pure solution, sodium sulfate binds to water and precipitates.

<h3>What is the purpose of the sodium sulfate?</h3>
  • Although it has numerous additional uses, sodium sulfate is primarily employed in the production of detergents and in the Kraft process of paper pulping.
  • The decahydrate's natural mineral form, mirabilite, accounts for about half of the world's output, with the other half coming from chemical byproducts. Sodium sulfate was used as a drying, isolating, and anhydrous salt for the 9-fluorenone.
  • To make sure that methylene chloride is present in a pure solution, sodium sulfate binds to water and precipitates.
  • The sodium salt of sulfuric acid is known as sodium sulfate. Na2SO4 is the chemical formula for sodium sulfate. The mineral thenardite, which is also known as anhydrous sulfate, is described as a white, crystalline solid, whereas the decahydrate Na2SO4. 10H2O is also known as Glauber's salt or the mirabilis salt.

Repulsion of electrons within two interacting molecules produces changes in electron distribution. This change in electron distr
ycow [4]

Answer:

D

Explanation:

This explains how two noble gases molecules can have an attractive force between them.

This force is called as van dar Waals forces.

It plays a fundamental role in fields in as diverse as supramolecular chemistry structural biology .

If no other forces are present, the point at which the force becomes repulsive rather than attractive as two atoms near one another is called the van der Waals contact distance. This results from the electron clouds of two atoms unfavorably coming into contact.[1] It can be shown that van der Waals forces are of the same origin as the Casimir effect, arising from quantum interactions with the zero-point field.[2] The resulting van der Waals forces can be attractive or repulsive.[3] It is also sometimes used loosely as a synonym for the totality of intermolecular forces.[4] The term includes the force between permanent dipoles (Keesom force), the force between a permanent dipole and a corresponding induced dipole (Debye force), and the force between instantaneously induced dipoles
