1 Fluoroantimonic acid muaj H0 (Hammett acidity function) tus nqi ntawm -31.3. Dissolves iav thiab ntau lwm yam ntaub ntawv thiab protonates ze li ntawm tag nrho cov organic tebchaw (xws li txhua yam nyob rau hauv koj lub cev). Cov kua qaub no yog khw muag khoom hauv PTFE (polytetrafluoroethylene) ntim
fluoroantimonic acid khaws cia nyob qhov twg?
Fluoroantimonic acid yog tsim los ntawm kev ua tib zoo sib xyaw hydrogen fluoride (HF) thiab antimony pentafluoride (SbF5). Fluoroantimonic muaj zog txaus noj nws txoj hauv kev los ntawm iav, txhais tau tias nws yuav tsum tau muab cia rau hauv tshwj xeeb tsim cov fluorine polymer coated ntim.
YKoj ua li cas fluoroantimonic acid?
Fluoroantimonic acid yog tsim los ntawm sib txuas hydrogen fluoride (HF) nrog antimony pentafluoride (SbF 5) , ua rau cov kua qaub uas yog 1016 zaug muaj zog dua sulfuric acid. Lub hydrogen ion nyob rau hauv HF yog txuas nrog fluorine los ntawm ib tug tsis muaj zog dipolar daim ntawv cog lus, uas account rau cov huab acidity ntawm lub superacid.
Leej twg ua fluoroantimonic acid?
Lub sij hawm superacid yog thawj zaug los ntawm James Bryant Conant hauv xyoo 1927 los piav txog cov kua qaub uas muaj zog dua li cov ntxhia hauv cov pa roj carbon monoxide.
Puas kua qaub rhuav tshem pob zeb diamond?
In luv, acids tsis yaj pob zeb diamond vim tias tsuas yog tsis muaj kua qaub txaus los rhuav tshem cov roj carbon muaj zog ntawm lub pob zeb diamond.

Ntawm qhov chaw twg tsis pom los ntawm qhov pom sab hauv?
Lub qhov ntswg zoo tshaj plawsyog nyob tom qab thiab yog li tsis pom nyob rau sab xub ntiag. Cov duab 9.1, 9.3, 9.5, 9.7, thiab 9.10 N/A Pab txhawb rau anterior cranial fossa; tsim ib feem ntawm qhov ntswg septum thiab qhov ntswg kab noj hniav;
Pom caproic acid nyob qhov twg?
Caproic acid muaj nyob rau hauv ntau yam nroj tsuag thiab tsiaj rog thiab roj . Cov khoom noj dab tsi muaj caproic acid? Cov khoom noj ntawm caproic acid Nws tshwm sim li glycerol ester hauv cov tsiaj rog zoo li cov tam sim no hauv butter, cheddar thiab lwm yam cheesesthiab hauv cov txiv maj phaub roj.
Qhov qhov muag tsis pom ntawm lub tsheb thauj khoom nyob qhov twg?
Tsev tsheb ciav hlau qhov muag tsis pom muaj xws li: Ncaj nraim rau pem hauv ntej ntawm lub tsheb thauj khoom mus txog 20 ko taw Ncaj nraim hauv qab lub tsheb thauj khoom li 30 ko taw Txhua sab ntawm lub tsheb thauj mus rau sab nraub qaum Tam sim ntawd hauv qab thiab qab tus neeg tsav tsheb qhov rais Puas muaj qhov muag tsis pom kev tsheb thauj mus los?
Pom elaidic acid nyob qhov twg?
Elaidic acid (EA) yog oleic acid trans isomer (trans-9-18: 1). Nws yog qhov tseem ceeb trans fatty acid nyob rau hauv Western noj mov. EA muaj nyob rau hauv margarine, ib nrab hydrogenated zaub roj, thiab zaub mov kib . Elaidic acid tsim li cas?
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
