Ammoniaak (Ammonia - wc puhastis) Ammoniaaki kasutatakse peamiselt väetiste, lõhkeainete ja polümeeride tootmisel. Looduses tekib orgaaniliste ainete lagunemisel. Laboris saadakse ammooniumsooladest. Ammoniaak on vees hästi lahustuv, läbipaistev, kirbe lõhnaga söövitav leeliseline aine, mille keemiline valem on NH3. Õhust kergem mürgine gaas. Vees lahustub väga hästi.

gravitational attraction keeping the ring particles on track between the orbits of the moon (Yenne 126). The first spacecraft flyby accomplished by Pioneer 11 in 1979 accomplished many findings of Saturn's composition. The planet has an internal heat source like Jupiter and radiates about twice as much energy as it receives from the Sun. As suspected, Saturn must have internal shells of liquid and metallic hydrogen, small amounts of helium, ammonia, water, and perhaps a small rocky core. A magnetic field was also discovered around Saturn, larger than the Earth's, but smaller than that of Jupiter. It is five times as weak as predicted by theory. The axis of this magnetic field is aligned parallel to the planet's rotation axis, contrary to thecircumstances in both Jupiter and Earth. The boundary of the magnetic field varies due to changes in the pressure of the solar wind on the sunward side,as was found in the case of Jupiter

commonly results in the formation of new C-N bonds. In alkaline solution, azobenzene results, whereas arsenic acid produces the violet-coloring matter violaniline. Chromic acid converts it into quinone, whereas chlorates, in the presence of certain metallic salts (especially of vanadium), give aniline black. Hydrochloric acid and potassium chlorate give chloranil. Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black. Hypochlorous acid gives 4-aminophenol and para-amino diphenylamine. Oxidation with persulfate affords a variety of polyanilines compounds. These polymers exhibit rich redox and acid-base properties. 5.

However, there are specialized heterotrophic bacteria capable also of decomposing cellulose, lignin, chitin, keratin, hydrocarbons, phenol, and other substances. Heterotrophic bacteria take an active part in the natural recycling of substances. Autrotrophic bacteria Autotrophic bacteria make their own food, either by photosynthesis (which uses sunlight, carbon dioxide and water to make food) or by chemosynthesis (which uses carbon dioxide, water and chemicals like ammonia to make food - these bacteria are called nitrogen fixers and include the bacteria found living in legume roots and in ocean vents). Fungi - is a member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds (British English: moulds), as well as the more familiar mushrooms.

popped. One barrel of crude oil, when refined, produces about 19 gallons of finished motor gasoline, and 9 gallons of diesel, as well as other petroleum products. Most of the petroleum products are used to produce energy. For instance, many people across the United States use propane to heat their homes and fuel their cars. Other products made from petroleum include: ink, crayons, bubble gum, dishwashing liquids, deodorant, eyeglasses, records, tires, ammonia, and heart valves. 17.3 How Does Oil Impact The Environment? Products from oil (petroleum products) help us do many things. We use them to fuel our airplanes, cars, and trucks, to heat our homes, and to make products like medicines and plastics. Even though petroleum products make life easier - finding, producing, moving, and using them can cause problems for our environment like air and water pollution. Over

chemical, called the reagent. For example, when a spy writes in iron sulfate, nothing will be visible until it is painted over with a solution of potassium cyanate, when the two chemicals will combine to form ferric ferrocyanide, or Prussian blue, a particularly lovely hue. The colorless writing of lead sub-acetate will turn into a visible brown compound when moistened with sodium sulfhydrate. Copper sulfate can be developed with ammonia fumes, and it may have been this chemical that was used for the secret writing on the handkerchief of George Dasch, leader of the eight Nazi spies who landed by submarine on Long Island in 1942 to blow up American defense plants, railroad bridges, and canal locks. The red letters that appeared as if by magic when the pungent ammonia reached it spelled out the names and addresses of a mail drop in Lisbon and of two reliable sources for help in the United States.
