Ammonium Nitrate vs Urea

Cov tshuaj uas muaj Nitrogen feem ntau yog siv los ua chiv vim tias nitrogen yog ib qho tseem ceeb ntawm cov nroj tsuag kev loj hlob thiab kev loj hlob. Ammonium nitrate thiab urea yog cov nitrogen uas muaj cov khib nyiab.

Ammonium nitrate muaj cov tshuaj formula NH₄NO_{3. Qhov no yog nitrate ntawm ammonia, thiab nws muaj cov qauv hauv qab no.}

Nyob rau hauv chav tsev kub thiab tus qauv siab ammonium nitrate muaj nyob ua ib qho tsw tsw, dawb crystalline khoom. Qhov no yog acidic ntsev nrog pH txog 5.4. Nws molar mass yog 80.052 g / mol. Melting point ntawm ammonium nitrate yog hais txog 170 ° C thiab nws decomposes thaum rhuab mus txog 210 ^{o C. Ammonium nitrate feem ntau yog siv rau kev ua liaj ua teb. Nws yog nplua nuj nyob rau hauv nitrogen, yog li nws yog siv los ua chiv, muab nitrogen rau cov nroj tsuag. Txij li thaum nws qhov kev sib cuag ncaj qha nrog tshuaj tsis muaj kev phom sij thiab toxicity ntawm nws tsawg dua, nws yog qhov zoo rau siv los ua chiv. Ntxiv mus, cua sov los yog ignition ua rau ammonium nitrate tawg. Yog li ntawd, nws yog siv los ua oxidizing tus neeg sawv cev hauv cov khoom tawg. Vim tias qhov xwm txheej tawg no, thaum khaws cov ammonium nitrate peb yuav tsum ceev faj ntxiv. Ammonium nitrate yog qhov ruaj khov, tab sis thaum nws nyob hauv lub xeev molten qhov kev pheej hmoo rau tawg yog siab dua. Qhov kev pheej hmoo yuav nce ntxiv yog tias nws tuaj yeem tiv tauj nrog cov ntaub ntawv oxidizable xws li roj, diesel, ntawv, rag, lossis straw. Kev tsim cov ammonium nitrate yog ib qho tshuaj lom neeg yooj yim. Thaum nitric acid reacted nrog ammonia kua, ammonium nitrate nyob rau hauv daim ntawv tov yog tsim. Industrially, concentrated nitric acid thiab ammonia gas yog siv rau ntau lawm. Txij li qhov no yog ib qho exothermic heev thiab ua phem tawm tsam, nws yog qhov nyuaj los tsim nws hauv cov nplai loj. Ua ntsev, ammonium nitrate yog soluble hauv dej. Yog li ntawd, thaum nws yog siv raws li ib tug fertilizer yuav ntxuav tawm thiab accumulates nyob rau hauv dej lub cev. Qhov no tuaj yeem ua rau tuag taus rau cov dej hauv dej.}

Urea

Urea muaj cov qauv molecular ntawm CO(NH₂)_{2 thiab cov qauv hauv qab no.}

Nws yog carbamide nrog pab pawg ua haujlwm C=O. Ob NH_{2 pab pawg raug khi rau cov carbonyl carbon los ntawm ob sab. Urea yog ib txwm tsim nyob rau hauv cov tsiaj txhu hauv cov metabolism hauv nitrogen. Qhov no yog hu ua lub voj voog urea, thiab oxidation ntawm ammonia lossis amino acids tsim urea hauv peb lub cev. Feem ntau ntawm cov urea yog tawm los ntawm ob lub raum nrog cov zis thaum qee qhov tawm hws. Cov dej solubility siab ntawm urea yuav pab tau thaum tshem tawm ntawm lub cev. Urea yog cov xim tsis muaj xim, tsis muaj ntxhiab tsw, thiab nws tsis muaj tshuaj lom. Ntxiv rau qhov ua cov khoom lag luam metabolic, nws qhov tseem ceeb yog siv los tsim cov chiv. Urea yog ib qho ntawm feem ntau cov nitrogen tso chiv, thiab nws muaj cov ntsiab lus nitrogen siab piv rau lwm cov khoom siv nitrogenous chiv. Hauv av, urea hloov mus rau ammonia thiab carbon dioxide. Cov ammonia no tuaj yeem hloov mus rau nitrite los ntawm cov kab mob hauv av. Tsis tas li ntawd, urea yog siv los tsim cov khoom tawg xws li urea nitrate. Nws kuj tseem siv los ua cov khoom siv raw los tsim cov tshuaj xws li plastics thiab adhesives.}

Qhov txawv ntawm Ammonium Nitrate thiab Urea yog dab tsi?

• Molecular formula of ammonium nitrate is NH₄NO_3. Molecular formula of urea is CO(NH₂)_2.

• Ammonium nitrate yog ntsev, qhov urea tsis yog. Nws yog carbamide (organic molecule).

• Thaum yaj hauv dej ammonium nitrate tsim cov kua qaub. Hauv qhov sib piv urea cov ntsiab lus tsis yog acidic lossis alkaline.
