According to the quantum-mechanical model, Phosphorous will have have similar chemical properties to an element with Z = 7

Quantum mechanics models describe the opportunity of putting electrons inside an atom through describing the main power degree, energy degree, orbital (arbitrary degree), and spin of. The quantum mechanics version is based totally on quantum theory, which states that rely has wave-like properties.

The quantum mechanical model is primarily based on quantum concept, which states that matter nonetheless has wave-related residences. The quantum mechanical model is critical for knowledge chemistry since it describes how electrons arise in atoms and how these electrons determine the chemical and physical homes of an detail.

The maximum particular clocks within the global, atomic clocks, are able to use standards of quantum idea to measure time. They screen the specific radiation frequency needed to make electrons leap among energy tiers.

explanation :

Nitrogen (Z = 7) is in Group 15 element

and will have similar properties to other Group 15 elements, like Phosphorous etc.

How can you recognize an alcohol?
gavmur [86]

Answer:

O D. It has an -OH group attached to the end of the molecule.

Explanation:

Some alcohols have hydroxyl group (OH) attached to the end of a molecule and some have it attached as a branch on the molecule

{ \rm{R - OH \:  : \: primary \: alcohol   \: (1 \degree)}}  \\  \\ { \rm{R -(OH) - R {}^{i}  \:  : secondary \: alcohol \: (2 \degree)}} \\  \\ { \rm{R - R {}^{i} (OH) - R {}^{ii}  \:  : tertiary \: alcohol \: (3 \degree)}}

  • R is aryl or alkyl group
  • OH is hydroxyl group

10)Calculate the molarity of a potassium dichromate solution prepared by placing 9.67 g of K Cro in a
lbvjy [14]

Answer:

0.33 M

Explanation:

From the question given above, the following data were obtained:

Mass of K₂Cr₂O₇ = 9.67 g

Volume of solution = 100 mL

Molarity =?

Next, we shall determine the number of mole in 9.67 g of K₂Cr₂O₇. This can be obtained as follow:

Molar mass of K₂Cr₂O₇ = (39×2) + (52×2) + (16×7)

= 78 + 104 + 112

= 294 g/mol

Mass of K₂Cr₂O₇ = 9.67 g

Mole of K₂Cr₂O₇ =?

Mole = mass /Molar mass

Mole of K₂Cr₂O₇ = 9.67 / 294

Mole of K₂Cr₂O₇ = 0.033 mole

Next, we shall convert 100 mL to litre (L). This can be obtained as follow:

1000 mL = 1 L

100 mL = 100 mL × 1 L / 1000 mL

100 mL = 0.1 L

Finally, we shall determine the molarity of the solution. This can be obtained as follow:

Mole of K₂Cr₂O₇ = 0.033 mole

Volume of solution = 0.1 L

Molarity =?

Molarity = mole / Volume

Molarity = 0.033 / 0.1

Molarity = 0.33 M

Thus, the molarity of the solution is 0.33 M
