Ammonia can form four hydrogen bonds per molecule. The lone pair on nitrogen can accept one hydrogen to form a hydrogen bond, and the three hydrogen atoms can bond to lone pairs to form three additional hydrogen bonds. However, if ammonia is the only molecule present, this bonding pattern is problematic because each molecule only has one lone pair per three hydrogen atoms. Thus, an average molecule would likely only have two hydrogen bonds, out of the maximum of four.
3H2 + N2 --> 2NH3 Since Hydrogen (H) and Nitrogen (N) both appear in nature diatomically they only appear as H2 and N2. We must add 3 molecules of Hydrogen and 1 molecule of Nitrogen to get 2 molecules of ammonia. We cannot, in nature, have half of a diatomic Hydrogen or Nitrogen atom, for that reason the equation must yield 2 molecules of Ammonia.
Yes, those are both ways of describing water. The reason for the difference, is that to an inorganic chemist, the water molecule is the combination of hydrogen and oxygen, hence hydrogen oxide, whereas to an organic chemist, the water molecule is the combination of hydrogen and the hydroxide radical (which is composed of hydrogen and oxygen).
In a water molecule, oxygen (which is a quite more electronegative than hydrogen), tends to attract electrons close to it, so it gets a residual negative charge, while hydrogen gets positively charged.That's the reason why water has a high boiling temperature, because water molecules establish electrostatic bonds, between the oxygen and hydrogen from different molecules, creating a kind of net of interactions, which make it harder to evaporate it.
Hydrogen bonding is when two water molecules get close enough and the hydrogen bonds in the molecule form a bond to other oxygen bonds. The reason this occurs is because to the charges in the elements. The hydrogen bonds have a slight positive charge while the oxygen bonds have a slight negative charge. They connect because opposite charges attract.
No, acetone cannot form hydrogen bonds with water. Acetone is a polar molecule with a carbonyl group, but it lacks hydrogen atoms bonded to highly electronegative atoms such as oxygen or nitrogen that are necessary for hydrogen bonding.
Ammonia is a polar molecule because the different electronegativity's of the nitrogen and the hydrogen molecules makes the hydrogen slightly positive and the nitrogen slightly negative. However there are 2 valance electons of the nitrogen atom which are not bonded to anything, which are called lone pairs. The lone pairs means that the ammonia molecule is not symmetrical therefore the electronegativity's do not cancel eachother, creating a polar molecule. ( The reason why the shape is no longer symmetircal is because lone pairs repel more than the bond pairs of the N-H, and essentially the bonding pairs are "squeezed" together, which accounts for the smaller than expected bond angle of 107 degrees)
Organic Chemistry it is the branch of Chemistry that studies molecules with carbon atoms. Ammonia (NH3) is a molecule that can be found in both the living and non-living realms. A good exemple of the later it is vulcanic activity. However, the reason this molecule is considered inorganic in Chemistry is that it does not have any carbon atom in it. Ammonia (NH3) contains only nitrogen and hydrogen atoms. Any molecule which contains carbon (C) is considered "Organic", e.g., CaCO3. Limestone, for example is primarily CaCO3, calcium carbonate, and is an organic molecule.

Ammonia dissolves in water due to its ability to form hydrogen bonds with water molecules. This interaction allows ammonia molecules to be surrounded by water molecules, leading to the formation of ammonium hydroxide. This process results in ammonia being soluble in water.

Two gasses at the same temperature have the same average amount of kinetic energy per molecule. An ammonia (NH3) molecule has less mass than hydrochloric acid (hydrogen chloride, HCl) molecule. Since the NH3 has the same amount of kinetic energy as the more massive HCl, ammonia molecules will move faster and thus diffuse faster. Kinetic energy ~ 1/2*m*v2
First, trace amounts of ammonia are everywhere. Second, there is no reason to run and hide from ammonia. Ammonia is nothing to be afraid of.
Hydrogen. It's reason is to be Hydrogen.
Ammonia is a toxic substance that can cause illnesses in animals. For this reason, ammonia must be eliminated from their bodies.
Water is not a hydrogen bond. Water is made up of hydrogen and oxygen atoms covalently bonded together by the sharing of electrons. Its molecular formula is H2O. Its structural formula is H-O-H. Water is a polar molecule, which is due to the fact that the large oxygen atom has a greater attraction for the shared electrons than the smaller hydrogen atoms. This makes the oxygen end of the molecule slightly negative and the hydrogen end slightly positive. For this reason, the oxygen atom of one water molecule will form a weak bond with another water molecule's hydrogen atom. This is the hydrogen bond.

In the illustration, d+ and d- refer to the partial positive and negative charges on the hydrogen and oxygen atoms.
The reason why it is advantageous to have weak hydrogen bonds between complementary base pairs and strong covalent bonds between phoshate and deoxyribose groups in a DNA molecule is because the strong covalent bonds running along the "ladder" of the DNA molecule (the phospate and deoxyribose units) keep the molecule together during its existence and more importantly its reproduction. The weak hydrogen bonds in the middle keep the reproduction cycle going on forever because it is able to perform an easy split between the hydrogen bonds throughout the middle of the molecule.
Hydrogen bonds. These bonds form between the positively charged hydrogen atoms in one water molecule and the negatively charged oxygen atoms in other water molecules. They give water its unique properties such as surface tension and cohesion.
