Hydrogen bond

this property it contains hydrogen bonding as well as dipole-dipole forces, two of the strongest and most significant forces that affect the solubility of the solution. Each separate group has hydrogen’s bonded on to the group, so either the oxygen’s having…

high per- centage of nitrogen. It has two conjugated ni- trogen rings, which are negatively charged, and a positively charged component consisting of nitrogen, carbon, and hydrogen. In addition to the high-energy content of this compound, as a salt, it has a lower heat of degradation due to the ease of breaking its ionic bonds. GAT was found to react with N100, a com- mon curative for HTPB. An alternative isocyan- ate curative was found, polyisocyanate (PAPI), with which it did…

Water, scientifically known as H2O is defined by online website as a transparent, odorless, tasteless liquid, a compound of hydrogen and oxygen, freezing at 32°F or 0°C and boiling at 212°F or 100°C. The earth is covered by approximately seventy-one percent (71%) of water and out of that percentage ninety-seven percent (97%) of it is saltwater and three (3%) percent of it is fresh water. Lakes, rivers, and swamps accounts for all surface freshwater supply and out of all the water on earth, only…

In the Monster Who Fed the World you learn about a German Jew named Fritz Haber. Haber was a genius chemist who learned how to take nitrogen out of the air and turn it into a liquid form to contain to use for fertilizer to help grow food for the overpopulated German nation and later the world. Unfortunately, some things and most things can have good and bad uses. Fritz Haber was born on December 9th, 1868. He was the son of a Jewish merchant in a small town. He had all ways longed for a better…

The remaining acid chloride then reacts with diethylamine. Diethylamine is used in excess to neutralize the hydrogen chloride produced in the reaction. The lone pair of electrons on the nitrogen atom performs a nucleophilic attack on the carbonyl carbon, while a pair of electrons in the double bond is pushed to the oxygen atom. When an electron pair from the oxygen atom restores the double bond, the chloride ion will act as a leaving group. The nitrogen atom is deprotonated by a chloride atom,…

A chemical reaction is a process in which one or more substances, which are the reactants, are converted to one or more different substances, which are the products. The substances in a chemical reaction are either chemical elements or compounds. There are different observations that indicate a chemical reaction has taken place. Formation of precipitate, which is a solid formed in a chemical reaction. Precipitate can take place when solutions containing ionic compounds are mixed and an insoluble…

The carbon supported PtFeS catalysts were prepared by a modified polyol method. In brief, 0.3 g carbon (Ketjen-black heat-treated at 2250 °C, SE = 160 m2 g-1) was dispersed in 135 g ethylene glycol. 5.993 g of 8 wt% H2PtCl6 (Umicore; Pt content, 39.8 wt%), 1.874 g of 8 wt% FeCl3. 6H2O (Sigma-Aldrich), and 0.352 g of 8 wt% (NH2)2SC (Sigma-Aldrich) previously mixed in ethylene glycol were added to the dispersion. The pH of the stirred reaction mixture was adjusted to ∼11 using 1 M NaOH dissolved…

and 18F. Fluorine is more stable in when it has 10 neutrons. Fluorine is a halogen and is placed on the right near the noble gas neon. B is for… Bonds Fluorine can bond with almost every element! It can create an ionic bond by bonding with another element such as sodium to create NaF. It can also use covalent bonds when bonding. Hydrogen…

reactants. These factors influence the rates of reaction by manipulating the frequency of successful collisions that occur between reactants. Successful collisions occur when reacting particles collide with enough force to separate or produce new bonds.…

I. Science fair question How does temperature affect the rate at which UV beads lose their color? II. Background Research Did you know that most of the ultraviolet light produced by the Sun is blocked by the atmosphere, but some light does still reach Earth? Ultra violet light can be detected using electronic devices. Important terms that will be discussed in this paper are ultraviolet light, photochromism, chemical reactions, and absolute zero. Relating to electromagnetic radiation having…
