Which of the following would most likely replace P in a solid solution?

I know for sure that it is not silicon. That means that it either has to be nitrogen or aluminum. Out of those two, I think nitrogen would make more sense.

Answer: Nitrogen

Explanation: Out of silicon, nitrogen and aluminum, Nitrogen can be used effectively and can replace Phosphorous in solid solution .

Because Nitrogen and Phosphorous belong to the same family of Pnictogens that is Group 15.

They are placed in the same group due to the similarities in the valence electrons of the outermost shell and due to the similarities in the chemical and physical properties.

Outermost electron configuration of Group 15 elements is

ns2 np3

where n = electron shell.

In the process of ionization, what is the relationship between the second ionization energy (I2) and the third ionization energy

dimulka [17.4K]

The first ionization energy is the energy that is obligatory in order to eliminate the first electron from an atom(neutral) in the GAS phase
, the second ionization energy is defined as the energy required to remove the second electron from an atom(+1 ion) in the GAS phase.
the third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.)
 Ionization energy will normally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods
hope it helps

Rank and explain how the freezing point of 0.100 m solutions of the following ionic electrolytes compare. List from lowest freez

Elden [556K]

Answer:

The solutions are listed from the lowest freezing point to highest freezing point.

Mg₃(PO₄)₂ - AlBr₃ - BeBr₂ - KBr

Explanation:

Colligative property of freezing point, is the freezing point depression.

Formula is:

ΔT = Kf . m . i

Where ΔT = T° freezing pure solvent - T° freezing solution

Kf is the cryoscopic constant

m is molality and i is the Van't Hoff factor (number of ions, dissolved in solution)

In this case, T° freezing pure solvent is 0° because it's water, so the Kf is 1.86 °C/m, and m is 0.1 molal.

The i modifies the T° freezing solution. The four salts, are ionic compounds, so for each case:

BeBr₂ → Be²⁺ + 2Br⁻ i = 3

AlBr₃ → Al³⁺ + 3Br⁻ i = 4

Mg₃(PO₄)₂ → 3Mg²⁺ + 2PO₄⁻³ i = 5

KBr → K⁺ + Br⁻ i = 2

Solution of Mg₃(PO₄)₂ will have the lowest temperature of freezing and the solution of KBr, the highest (always lower, than 0°).
