Hello!
The phase change in which a substance changes from a gas directly to a solid is nominated "deposition".
Hugs!
If atoms stay in a fixed position that means they are a solid
Serotonin acts as a weak base and has a pkb = 3. 84. The ph of a solution made by adding 0. 025 m of serotonin in water is 2.4.
A molecule called serotonin delivers information between nerve cells in the brain and other parts of the body. Body processes like mood, sleep, digestion, nausea, wound healing, bone health, blood clotting, and sexual desire are all significantly influenced by serotonin.
Tryptophan, an important amino acid, is used to make serotonin. This amino acid, which must be ingested by food, is frequently present in foods including nuts, cheese, and red meat. Lower amounts of serotonin can result from tryptophan insufficiency. Anxiety or depression may come from this, among other mood disorders. The chemical serotonin is essential for elevating mood and lowering anxiety.

Answer:
4.13×10²⁷ molecules of N₂ are in the room
Explanation:
ideal gases Law → P . V = n . R . T
Pressure . volume = moles . Ideal Gases Constant . T° K
T°K = T°C + 273 → 20°C + 273 = 293K
Let's determine the volume of the room:
18 ft . 18 ft . 18ft = 5832 ft³
We convert the ft³ to L → 5832 ft³ . 28.3L / 1 ft³ = 165045.6 L
1 atm . 165045.6 L = n . 0.082 L.atm/mol.K . 293K
(1 atm . 165045.6 L) / 0.082 L.atm/mol.K . 293K = n
6869.4 moles of N₂ are in the room
If we want to find out the number of molecules we multiply the moles by NA
6869.4 mol . 6.02×10²³ = 4.13×10²⁷ molecules
Answer: Conclusion
