A gaseous compound of hydrogen and nitrogen, NH3, with a pungent smell and taste: -- often called volatile alkali, and spirits of hartshorn.
Helpful?           1
A colorless gas, formula NH3, with a sharp, irritating odor, having a density about six- tenths that of air at the same temperature and pressure (0.7720 g cm−3 at STP). A reduced nitrogen gas, NH3 is emitted in large quantities from animal feedstocks, sewerage plants, etc. Ammonia is very soluble in water and is scavenged from the lower atmosphere by clouds. It is the most abundant alkaline gas in the atmosphere and as such plays a large role in neutralizing acidity from sulfuric and nitric acids via formation of the ammonium ion. Large quantities of ammonia gas, and probably even ammonia crystals, occur in the atmospheres of the large planets Saturn and Jupiter. See air.

is a colourless gass with the well known pungent odour found in household cleaners. NH3 iis produced both by natural and human sources including the decay of plant material and animal waste. In Alberta, the fertilizer and commercial feedlots are the main industrial sources of NH3.

A colorless gaseous alkaline compound (chemical formula NH3). It is very soluble in water, has a characteristic pungent odor, is irritant, is lighter than air, and is formed as a result of the decomposition of most nitrogenous organic material. Because of its characteristics, ammonia is normally utilized in solution with water.

(NH3) - Type of balloon that uses ammonia as its lifting agent instead of helium, hydrogen or coal gas. Becoming very popular in 1990's. Much less costly than flying other gas bags. Has approximately .5 lifting power of helium. Popularized by Tim Cole and Dennis Brown of Colorado. Ammonia gas is readily available in agricultural areas of the USA.

(NH 3 & NH4+): Ammonia is a gaseous, alkaline compound of nitrogen and hydrogen (NH3) . High ammonia levels in an aquarium are caused by the absence of nitrifying bacteria (nitrosomonas). For more information about Ammonia and the nitrogen cycle, see article 0009 - Introduction to the Nitrogen Cycle.

NH3, this is one of the steps in the nitrogen cycle. It is toxic to most creatures, and should be at un-measurable levels after a tank has cycled.

an inorganic form of nitrogen, is contained in fertilizers, septic system effluent, and animal wastes. It is also a product of bacterial decomposition of organic matter. Ammonia NH3-N (NH3-N) becomes a concern if high levels of the un-ionized form are present. In this form NH3-N can be toxic to aquatic organisms. The presence of un-ionized ammonia is a function of the NH3-N concentration, pH, and temperature. Conversion of NH3-N to nitrite nitrogen by nitrification requires large quantities of oxygen which can kill aquatic organisms due to the lowered dissolved oxygen concentrations in water. NH3-N concentrations are reported in mg/L NH3-N.
