Bacriminta nitrogen. amooniyam

amooniyam waxaa ka mid ah in koox ka mid ah nitrogenous ugu muhiimsan ee Bacriminta. Nitrogen qabata kaalin muhiim ah nolosha geedka. walax Tan waxaa ka mid ah in Halabuurka ee chlorophyll, taas oo ah protein ah aqbalana iyo tamarta qoraxda, taas oo lagama maarmaan u ah dhismaha unugyada nool.

Geedaha ay awoodaan in ay ku baabbi'iyee nitrogen xidhxidhan oo kaliya ee foomka of amides, ammonium cusbada, Nitrate. Qadarka yar ee wax la aasaasay by howlgalka of sheyga ciidda. Waa in la ogaadaa in beeraha casriga ah ma jiri karo oo aan sal-dhigida ee dheeraadka ah ee group nitrogen bacriminta, kuwaas oo ka soo warshadaha nitrogen Hawada qabanaya soo jeedaan. ANAAD ka mid ahaa in this category yihiin midba midka kale ka duwan oo ah qaab dawlad wajiga xarunta (dareere ama adke). Qarsan xumadoodu physiologically iyo Bacriminta acidic.

amooniyam, kuwaas oo formula NH ₄ NO _3, waa cad walax crystalline, oo ka kooban shan iyo soddon boqolkiiba nitrogen ee amooniyam iyo foomka ammonium ah. Labada nooc kuwan waxaa si sahal ah u nuugo by dhirta. A amooniyam granular waxaa loo isticmaalaa in tiro badan oo ka hor shuqullada beeridda iyo sida labiska top. Inta ay yar yar waxaa loo isticmaalaa in soo saaridda ee qarxa.

amooniyam noqon kartaa noocyada kala duwan. Noocyada A iyo B, tusaale ahaan, waxaa loo isticmaalaa ujeedooyin warshadaha ee isku qarxa (ammonal, reer Cammoon).

Waayo, wax soo saarka ee bacrimin codsatay ammonia iyo nitric acid. Miisaanka uu leeyahay kelli ah ka helay xarunta 80.043 AMU amooniyam saafi ah ku jira boqolkiiba lixdan oxygen, hydrogen boqolkiiba shan iyo shan iyo soddon boqolkiiba nitrogen (aan ka yarayn afar iyo soddon boqolkiiba jajab nitrogen sheyga farsamo).

Iyada oo ku xidhan heerkulka, waxaa hadhay shan beddelka crystal walax. All waa thermodynamically deggan cadaadiska Hawada. Waayo, wax ka beddelid kasta uu gaar ah ay gobolka heerkulka gaar ah iyo kala guurka ah polymorphic lug badalaya qaabka baraf, nuugista ama sii daayo kulaylka, isbedel kadis ah in mugga gaar ah, entropy, awoodda kulaylka, iyo si bixi. transformations noocan oo kale ah waxaa loo arkaa enantiotropically - karo.

amooniyam waa wakiil oksidheeyeyaal ah oo awood u taageeraya sari. In kiiska halkaas oo waxyaabaha daatay kaamerada ma ay awoodaan in ay si xor ah laga saaray, walaxda qarxin karaan (qarxi) xaaladaha qaarkood.

Markii loo feydo kulka sare (laba boqol iyo toban - boqol iyo labaatan degrees) in meel bannaan oo u xiran yihiin, ammonia ururayaa, fiirsashada of nitric acid loo dhigi. Marka tan la eego, waxaa jira hoos u dhac weyn oo dareen-celin kala daatay ee. kala daatay kaamerada ku dhowaad ma joojin. Markii loo feydo kulka ka weyn, walax lagu qayilo ka sii deg deg ah ee ammonia, falcelinta waa ururtay bilaabaa inuu ka duuli la xawaaraha badan. Waxa kale oo ay keeni kartaa qarax.
