UAN yog kev daws ntawm urea thiab ammonium nitrate hauv dej siv los ua chiv. Qib feem ntau siv ntawm cov tshuaj chiv no yog UAN 32.0. 0 (32% N) kuj hu ua UN 32 los yog UN-32 , uas muaj 45% ammonium nitrate, 35% urea thiab tsuas yog 20% dej.
Piv txwv li, yog urea thiab ammonium nitrate tib yam?
Urea thiab ammonium nitrate yog ob hom tshuaj sib txawv kiag li. Molecular formula ntawm Ammonium nitrate yog: (NH4) (NO3) los yog N2H4O3. Txij li thaum lawv cov mis molecular txawv, lawv yuav nthuav tawm lawv tus kheej cov khoom tshwj xeeb. Yog li, nws yog qhov yooj yim, UREA tsis yog ib yam raws li AMMONIUM NITRATE.
Tsis tas li ntawd, pes tsawg nkas loos ntawm 32 nitrogen nyob rau hauv ib tuj? Ib feem plaub ntawm cov nitrogen yog ammonic, ib feem plaub yog nitrate thiab ib nrab yog urea. Nws hnyav 11.08 lbs. rau nkas loos , muaj pH ntawm kwv yees li 7 thiab muaj qhov tsis zoo vapor siab. Txhua nkas loos of UA 32 % Cov tshuaj muaj 3.55 lbs.
Kuj nug yog, ua li cas ua tau?
Cov kua dej urea-ammonium nitrate ( UA ) chiv yog qhov yooj yim los tsim. Ib tug rhuab tov uas muaj yaj urea yog tov nrog ib tug rhuab tov ntawm ammonium nitrate los ua ib tug ntshiab kua chiv. UA yog ua hauv cov khoom siv hauv qee qhov chaw lossis hauv cov txheej txheem txuas ntxiv hauv lwm tus.
10 34/0 kua chiv hnyav npaum li cas?
Ua kua:
| Ua kua: | ||
|---|---|---|
| 1 nkas loos 28% (28-0-0) | = | 10.66 Ib. |
| 1 nkas loos 10-34-0 | = | 11.65 Ib. |
| 1 hli 7-21-7 | = | 11.00 Nws. |
| 1 nkas loos 9-18-9) | = | 11.11 Ib. |

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
