Lub degree ntawm oxidation ntawm nitrogen - kawm deal

Nitrogen - tej zaum cov feem ntau cov tshuaj lub caij nyob rau hauv lub hnub ci zog. Yuav kom ua tau ntau tshaj ib qho, lub nitrogen yog ranked 4 feem ntau. Nitrogen nyob rau hauv cov xwm - lub inert roj.

Qhov no gas twb tsis muaj xim, tsis muaj tsis hnov tsw, nws yog heev yooj yim mus yaj nyob rau hauv dej. Txawm li cas los, nitrates, ntsev yuav teb zoo heev nrog dej. Nitrogen muaj ib tug uas tsis muaj kev ceev.

Nitrogen - tsab caij. Muaj yog speculation hais tias nws tau txais nws lub npe los ntawm lub ancient Greek lus, uas translates rau txhais hais tias nws "tsis muaj sia, puas." Yog vim li cas yog nws xws li ib tug tsis zoo tus cwj pwm mus rau lub nitrogen? Tom qab tag nrho, peb paub hais tias nws yog ib feem ntawm cov protein, thiab ua pa tsis tau nws yog yuav luag tsis yooj yim sua. Nitrogen plays ib qho tseem ceeb luag hauj lwm nyob rau hauv cov xwm. Tab sis qhov no gas yog inert cua. Yog hais tias nws yog coj no rau nws yog dab tsi nyob rau hauv nws cov thawj daim ntawv no, tej zaum nws yuav muaj ntau yam tshwm sim. Tus neeg tej zaum yuav txawm tuag ntawm txhawm chim. Tom qab tag nrho, vim hais tias cov nitrogen yog hu ua lifeless hais tias nws tsis txhawb combustion tsis respiration.

Nyob rau hauv tej yam kev mob, qhov no gas reacts nrog cov lithium txoj kev compound xws li lithium nitride Li3N. Raws li peb tau pom, cov neeg kawm ntawv ntawm oxidation ntawm nitrogen nyob rau hauv xws li ib tug compound yog 3. Nrog lwm co thiab nitrogen tebchaw, ntawm chav kawm, kuj reacts, tiam sis tsuas yog cua sov los yog los ntawm kev siv ntau catalysts. Los ntawm txoj kev hais lus -3 - ib tug tsawg dua degree ntawm oxidation ntawm nitrogen vim tsuas yog peb electron yuav tsum tau mus kiag li sau cov txheej zog.

Qhov no qhia muaj ntau yam ntawm lub ntsiab. Txhua degree ntawm oxidation ntawm nitrogen nws muaj nws compound. Tej tebchaw yog zoo dua los cia li nco ntsoov.

Yog li, lub oxidation tooj ntawm -3 zaum yuav nyob rau hauv nitrides. Lub degree ntawm oxidation ntawm nitrogen nyob rau hauv ammonia kuj sib npaug zos rau -3, li tab sis tej zaum nws yuav zoo li paradoxical. Ammonia yog ib tug tsis muaj kob roj nrog ib tug heev pungent tsw. Nco ntsoov ammonia. Nws qauv kuj muaj xws li ammonia NH3. Tso txawm tshuaj nrog ammonia. Yeej, lawv muaj qhia rau tsaus muag, kiv taub hau, mob cawv intoxication. Pungent tsw sai sai ua rau yus txoj kev xav nyob rau hauv tus neeg mob. Tseem, tom qab tag nrho cov nws tsis kam ua dab tsi rau nws los tshem tawm qhov no "tus tshwj ntxim".

Feem ntau yeej tsis muaj xws li nitrogen oxidation degree yog -1, thiab -2. Tus thawj yog pom nyob rau hauv lub thiaj li hu ua pernitridah, cov uas nws muaj nqis ntsoov teev N2H2. Qhov kawg degree ntawm oxidation tshwm sim nyob rau hauv NH2OH kev twb kev txuas. Xws li ib tug complex compound yog heev tsis ruaj tsis khov muaj zog puag. Mas siv nyob rau hauv cov organic synthesis.

Cia peb tig mus rau lub siab dua degrees ntawm oxidation ntawm nitrogen, uas muaj tseem heev ob peb. Lub degree ntawm oxidation ntawm nitrogen tshwm sim nyob rau hauv ib tug compound xws li cov pa roj nitrous oxide (N2O). Thaum ib tug me me npaum li cas ntawm cov roj yog xyaum tsis cai kev phiv. Feem ntau nws yog siv nyob rau hauv me me koob tshuaj rau tshuaj loog. Txawm li cas los, Yog hais tias lub sij hawm ntawm nqus tau pa ntawm no gas yog txaus ntev, ces tau txoj kev tuag los ntawm txhawm chim.

Lub degree ntawm oxidation ntawm TSIS MUAJ 2 muaj nyob rau hauv lub chaw tub rog. Cov oxidation 3 - nyob rau hauv lub oxide N2O3. Lub degree ntawm oxidation ntawm +4 - oxide rau NO2. Qhov no gas muaj ib tug reddish-xim av xim thiab ib tug pungent tsw. Nws yog ib tug acidic oxide.

5 - ntau dua degree ntawm oxidation nyob rau nitrogen. Nws tshwm sim nyob rau hauv nitric acid , thiab tag nrho cov ntsev, nitrates.
