Explanation:

Condensation is defined as the process in which vapor or gaseous state of a substance changes into liquid state.

Evaporation is defined as the process in which liquid state of a substance changes into gaseous state.

Sublimation is defined as the process in which a solid substance directly changes into gaseous state without undergoing liquid state.

Freezing is defined as the process in which liquid state of a substance changes into solid state.

Therefore, the given terms are matched as follows.

  • Condensation : D) A phase change from a gas to a liquid
  • Evaporation : B) A phase change from a liquid to a gas
  • Sublimation : C) A phase change from a solid to a gas
  • Freezing : A) A phase change from a liquid to a solid

F a shell can hold a maximum of 32 electrons, what is the value of n? 2 3 4 5
Arte-miy333 [17]

Answer: 4

Explanation:

Principle Quantum Numbers: This quantum number describes the size of the orbital. It is represented by n.

Azimuthal Quantum Number: This quantum number describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number: This quantum number describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from (-l\text{ to }+l). When l = 2, the value of m_l will be -2, -1, 0, +1, +2.

Given : a f subshell, thus l = 3 , Thus the subshells present would be 3, 2, 1, 0 and thus n will have a value of 4.

Also electrons give are 32.

The formula for number of electrons is 2n^2.

2n^2=32

n=4

Thus principal quantum no will be n= 4.

In which state of the following compounds does nitrogen have the most positive oxidation state? group of answer choices no2 nano
Amiraneli [1.4K]

The compound nitrogen have most positive oxidation state is NO₂. The correct option is b.

<h3>What is oxidation state?</h3>

The total number of electrons gained or lost by an atom in order to form a chemical bond with another atom.

The charge on an ion is equal to the sum of the oxidation states of all the atoms in the ion. A substance's more electronegative elements are given a negative oxidation state.

A positive oxidation state is assigned to the less electronegative element.

Thus, the correct option is b, NO₂.
