Ammonia NH 3 , colourless, pungent gas composed of nitrogen and hydrogen. It is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds. The major use of ammonia is as a fertilizer.

The effect of heat and ammonia treatment on colour response of oak wood Quercus robur and comparison of some physical and mechanical properties. Corresponding author. In this paper the effect of heat and ammonia treatment on the change in colour of oak wood Quercus robur. The results show that the heat treatment contributed to darkening of sapwood and heartwood and the total colour change increased up to

Deionized, tap and two kinds of commercially available mineralized water, after supplementation with ammonia, were treated with low-pressure, low-temperature glow plasma GP of low frequency. Treating hard water with ammonia provided the removal of permanent and temporary water hardness already at room temperature. On such treatment, mineralized water supplemented with ammonia was partly demineralized. The rate and yield of precipitation depended on the concentration of admixed ammonia and the GP treatment time. Ammonia served as a ligand of calcium, magnesium and ferric central atoms of corresponding salts constituting the hardness. Moreover, ammonia constituting the atmosphere of the treatment was arrested inside aqueous clathrates. So, stabilized ammonia solutions could potentially be utilized as an environmental-friendly nitrogen fertilizer.

Ammonia is a compound of nitrogen and hydrogen with the formula NH 3. A stable binary hydride , and the simplest pnictogen hydride , ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste , particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water.

With the analysis of the molecular dynamics trajectories by use of the bond auto-correlation function, we identify three distinct pressure-temperature regions for local chemical structures of ammonia. We derive the diffusivity and viscosity of strong correlated ammonia with high accuracy through fitting the velocity and stress-tensor autocorrelation functions with complex functional form which includes structures and multiple time scales. The statistical error of the transport properties is estimated.

Ammonia is highly stable. However, it can be decomposed into hydrogen and nitrogen by passing over heated metallic catalysts or when electric discharge is passed through it. Ammonia is combustible in air. However, it will burn in an atmosphere of oxygen. Ammonia molecule has a strong tendency to donate its lone pair of. For example,. Ammonia gets oxidized to nitrogen, when passed over heated metal oxides.

Selected chemical and physical properties, toxicokinetic and mechanistic data, and inhalation-exposure levels from the National Research Council NRC and other agencies are also presented. Ammonia is a corrosive alkaline gas at room temperature Budavari et al. It is colorless and has a distinctive odor that has been described as sharp, pungent, and irritating HSDB

ГЛАВА 54 - Пусти. А потом раздался нечеловеческий крик. Это был протяжный вопль ужаса, издаваемый умирающим зверем. Сьюзан замерла возле вентиляционного люка. Крик оборвался столь же внезапно, как и раздался.

 Нет! - отрезала.  - Не думаю, что он знал, что имеет дело с вирусом. Я думаю, он был введен в заблуждение. Бринкерхофф молчал. Мидж Милкен явно чего-то не поняла.

 - Ах да… Я, кажется, что-то такое читала. - Не очень правдоподобное заявление. - Согласна, - сказала Сьюзан, удивившись, почему вдруг Хейл заговорил об.  - Я в это не верю.

 Да. К счастью, Дэвид это обнаружил. Он проявил редкую наблюдательность. - Но ведь вы ищете ключ к шифру, а не ювелирное изделие.

Беккер кивнул. - Ты же сказала, что не колешься. Девушка засмеялась: - Это же чудо-маркер. Я чуть кожу не содрала, пытаясь его стереть. Да и краска вонючая.

Казалось, Стратмор ее не слышал. - В последние несколько лет наша работа здесь, в агентстве, становилась все более трудной. Мы столкнулись с врагами, которые, как мне казалось, никогда не посмеют бросить нам вызов. Я говорю о наших собственных гражданах. О юристах, фанатичных борцах за гражданские права, о Фонде электронных границ - они все приняли в этом участие, но дело в другом. Дело в людях. Они потеряли веру.

Смерть остановит боль. Она будет опять рядом с Дэвидом. Шифровалка начала вибрировать, словно из ее глубин на поверхность рвалось сердитое морское чудовище. Ей слышался голос Дэвида: Беги, Сьюзан, беги.

 Ужасное уродство, правда.
