Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq).
In an aqueous solution, it can be expelled by boiling. The aqueous solution of ammonia is basic, and may be described as aqueous ammonia or ammonium hydroxide. [30] The maximum concentration of ammonia in water (a saturated solution) has a specific gravity of 0.880 and is often known as '.880 ammonia'. [31]
Ammonolysis can be used to synthesize nitrides (and oxynitrides) by reacting various metal precursors with ammonia, some options include chemical vapor deposition, [3] treating metals or metal oxides with ammonia gas, [15] or liquid supercritical ammonia (also known as "ammonothermal" synthesis, analogous to hydrothermal synthesis).
Solutions obtained by dissolution of lithium in liquid ammonia. The solution at the top has a dark blue color and the lower one a golden color. The colors are characteristic of solvated electrons at electronically insulating and metallic concentrations, respectively. A lithium–ammonia solution at −60 °C is saturated at about 15 mol% metal ...
Hydrogen can also be produced from water and electricity using electrolysis: at one time, most of Europe's ammonia was produced from the Hydro plant at Vemork. Other possibilities include biological hydrogen production or photolysis , but at present, steam reforming of natural gas is the most economical means of mass-producing hydrogen.
Studying the whales, scientists came up with an idea to invent the submarine, so as to sail under the vast oceans. The design of the submarines is based on the shape of whales.
Coyotes can also be very territorial and aggressive to people (or animals) that they don't know very well. It wouldn't be wise to have a coyote in a home with children or bring them around strangers.
Cases of norovirus appear to be on the rise in various parts of the U.S., according to data from the Centers for Disease Control and Prevention. More than 90 norovirus outbreaks were reported ...
