Muaj ntau yam loj ammonia Cov chaw tsim khoom thoob ntiaj teb, ua tau tag nrho ntawm 144 lab tonnes ntawm nitrogen (sib npaug rau 175 lab tonnes ntawm ammonia ) xyoo 2016. Suav teb ua 31.9% ntawm kev tsim khoom thoob ntiaj teb, tom qab ntawd Russia nrog 8.7%, Is Nrias teb nrog 7.5%, thiab Tebchaws Meskas nrog 7.1%.
Thiab cov lus nug yog, qhov twg ammonia tsim nyob rau hauv lub cev?
Koj lub siab yuav tsis ua haujlwm zoo yog tias koj muaj qib siab ammonia hauv koj cov ntshav. Ammonia yog ib yam tshuaj uas ua los ntawm cov kab mob hauv koj cov hnyuv thiab koj lub cev cell thaum koj ua cov protein. Koj lub cev kho ammonia raws li cov khoom pov tseg, thiab tshem tawm los ntawm lub siab.
Ib yam li ntawd, lub teb chaws twg yog cov neeg tsim khoom loj tshaj plaws ntawm ammonia? Tuam Tshoj
Yog li ntawd, lawv ua li cas ammonia?
Cov txheej txheem Haber muab cov nitrogen los ntawm huab cua nrog hydrogen muab los ntawm cov pa roj (methane) rau hauv ammonia . Cov tshuaj tiv thaiv yog reversible thiab ntau lawm ntawm ammonia yog exothermic. Lub catalyst yog qhov tseeb me ntsis nyuab dua li cov hlau ntshiab.
Ammonia puas tuaj yeem tua koj?
TEKAMAH, Neb. if koj nqus tau nws thiab nws nkag mus rau hauv koj cov hlab cua thiab koj lub ntsws nws yuav ua rau hlawv muaj qhov ntawd yog dab tsi yuav feem ntau tua koj - yog koj nqus tau concentrated ammonia roj, hais tias Nebraska Regional Poison Center's Ron Kirschner.

Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov twg hauv qab no zoo tshaj plaws sawv cev rau qhov sib npaug molecular rau cov tshuaj tiv thaiv ntawm aqueous ammonia nrog sulfuric acid?
Nqe Lus Nug: Qhov Sib npaug Sib npaug rau Kev Ua Haujlwm Ntawm Aqueous Sulfuric Acid Nrog Aqueous Ammonia yog 2NH3 (aq) + H2SO4 (aq) --> (NH4) 2SO4 (aq) A
Qhov twg yog qhov zoo dua qhov kev xaiv ntuj los yog kev xaiv dag Yog vim li cas?
Thaum lub sij hawm xaiv ntuj, hom ciaj sia thiab kev yug me nyuam txiav txim siab cov yam ntxwv. Txawm hais tias tib neeg tuaj yeem txhim kho lossis ua rau lub cev muaj peev xwm los ntawm kev xaiv kev yug me nyuam, qhov xwm txheej cuam tshuam nws tus kheej nrog cov yam ntxwv uas tso cai rau qhov zoo rau cov tsiaj muaj peev xwm ua phooj ywg thiab muaj sia nyob
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
