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.

A gas is collected in a 34.3L container at a temperature of 31.5°C. Later, the container has a volume of 29.2L, a temperature of
goldenfox [79]

Answer:

108 kPa  

Step-by-step explanation:

To solve this problem, we can use the <em>Combined Gas Laws</em>:

p₁V₁/T₁ = p₂V₂/T₂             Multiply each side by T₁

   p₁V₁ = p₂V₂ × T₁/T₂      Divide each side by V₁

      p₁ = p₂ × V₂/V₁ × T₁/T₂

Data:

p₁ = ?;                 V₁ = 34.3 L; T₁ = 31.5 °C

p₂ = 122.2 kPa; V₂ = 29.2 L; T₂ = 21.0 °C

Calculations:

(a) Convert temperatures to <em>kelvins </em>

T₁ = (31.5 + 273.15) K = 304.65 K

T₂ = (21.0 + 273.15) K = 294.15 K

(b) Calculate the <em>pressure </em>

p₁ = 122.2 kPa × (29.2/34.3) × (304.65/294.15)  

   = 122.2 kPa × 0.8542 × 1.0357

   = 108 kPa
