Pepsi [2]3 years ago
3 0

Answer:

2, 8, 18

Explanation:

The number of orbitals for any level of interest n is calculated by a formula o = n^2. Since each orbital contains a maximum of 2 electrons, we can calculate the total number of electrons in an nth orbital by e = 2n^2.

  • As a result, the first energy level for n = 1 can hold a maximum of 2n_1^2 = 2\cdot 1^2 = 2 electrons,
  • The second energy level can hold a maximum of 2n_2^2 = 2\cdot 2^2 = 8 electrons,
  • The third energy level can hold a maximum of 2n_3^2 = 2\cdot 3^2 = 18 electrons.

Answer:

The natural ligand of the cytosolic Aryl hydrocarbon receptor which is still not known.

Explanation:

Dioxin is formed during some industrial chemical processes. It is considered harmful because it causes cancer, weakens the immune system, results in nervous breakdown and also affects reproduction.

The mechanism of operation of Dioxins has not been fully understood. However, it is known that dioxins works through a receptor known as the Aryl hydrocarbon receptor. This receptor is useful in gene expression and also acts as a transcription factor.

When gases dissolve in gases or when liquids and gases dissolve in liquids, _________eventually spreads the particles evenly thr
natulia [17]

When gases dissolve in gases or when liquids and gases dissolve in liquids, particles movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.​

Explanation:

When gases dissolve in gases or when liquids and gases dissolve in liquids, particle movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.​

Solid particles do not dissolve easily like liquids and gases dissolve. Solid particles when dissolved in solid the particles moves very little. After getting heated and becomes molten then they get mixed.

But in the liquids and gases atoms moves and the particles get eventually spread and also get mixed after cooled.

What does lower case k stand for?
DaniilM [7]
Just for more clarification, lowercase k is the rate constant. Uppercase K is the equilibrium constant. You can actually use k to find K (equilibrium constant). K=k/k' This means that the equilibrium constant is the rate constant of the forward reaction divided by the rate constant of the reverse reaction

This sounds good so far.
