Cov khoom sib xyaw yog cov khoom ntawm chav tsev kub feem ntau vim yog di-hydrogen bonding thiab dipole-dipole kev sib cuam tshuam. Txawm hais tias ammonia borane thiab diammonate ntawm diborane muaj tib cov tshuaj formula lawv txawv heev nyob rau hauv stability.
Puas ammonia puas muaj zog?
Ammonia yog roj tsis muaj xim nrog tus yam ntxwv tsw ntxhiab tsw. Nws yog qhov sib dua ntawm huab cua, nws qhov ceev yog 0.589 npaug ntawm huab cua. Nws yog yooj yim liquefied vim muaj zog hydrogen bonding ntawm molecules; cov kua boils ntawm −33.3 ° C (−27.94 ° F), thiab khov rau dawb crystals ntawm −77.7 ° C (−107.86 ° F).
YPuas ammonia borane soluble hauv dej?
7.4 Kev Hloov Hlau Hlau Nanoparticles Catalysts hauv Hydrogen Generation los ntawm Hydrolysis ntawm Ammonia Borane. Ammonia borane dissolves hauv dej tsim cov tshuaj ruaj khov thaum tsis muaj cua. Txawm li cas los xij, hydrogen raug tso tawm raws li nws cov kua qaub catalyzed hydrolysis hauv cov kua dej (Eq. (7.2)) [124].
Vim li cas NH3BH3 yog ib qho khoom?
NH3BH3 yog cov khoom nyob rau hauv chav tsev kub nrog lub siab melting point ntawm 104 ° C thaum piv rau cov tebchaw xws li isoelectronic C2H6 uas melts ntawm -183 ° C. Qhov no feem ntau yog vim dipole-dipole kev sib cuam tshuam thiab lub network ntawm dihydrogen bonding.
Ammonia borane ua li cas?
Ammonia borane tuaj yeem tsim los ntawm sib txuas ammonia chloride thiab sodium borohydride thiab tom qab ntawd decomposing rau hauv THF. Nws kuj tuaj yeem tsim los ntawm kev sib xyaw diborane thiab ammonia ntawm qhov kub thiab txias.

Yuav ua li cas ua kom khov khov ua haujlwm li cas?
Cryonics siv qhov kub qis dua -130 ° C, hu ua cryopreservation, txhawm rau txhawm rau khaws cov ntaub ntawv hlwb txaus kom tso cai rau kev txhawb siab yav tom ntej ntawm tus neeg cryopreserved. Cryopreservation tuaj yeem ua tiav los ntawm kev khov, freezing nrog cryoprotectant kom txo cov dej khov puas, lossis los ntawm vitrification kom tsis txhob muaj dej khov puas .
Vim li cas borane tsis ruaj khov?
Vim li cas qhov nruab nrab borane-hydroperoxide adduct tsis ruaj khov? Boron muaj qhov khoob p-orbital thiab muaj hluav taws xob ntau vim yog qhov tsis tiav octet . Vim li cas borane tsis ruaj khov thiab rov ua haujlwm? Cov ntawv sau cov duab:
Vim li cas ammonia inhalants tawm hauv Tshuag?
US airlines tab tom thov cov neeg tswj hwm kom tsim kom muaj kev tsis txaus ntawm cov ntsev ntsev, tseem hu ua ammonia inhalants. … Ib qho laj thawj rau cov khoom tsis txaus: cov kev cai cuam tshuam txog tshuaj nyob rau hauv Txoj Cai CARES, tib txoj cai lij choj uas tau tso cai rau Asmeskas cov tuam txhab lag luam ntau lab nyiaj thoob ntiaj teb kev pab cuam .
Vim li cas cov dej khov thiab qhov dej khov zoo ib yam?
Thaum txias, cov khoom hauv cov kua poob zog, tsis txhob txav mus los thiab nyob rau hauv qhov chaw ruaj khov, ua kom muaj zog. Freezing tshwm sim ntawm qhov kub ib yam li melting, li no, lub melting point thiab khov point ntawm ib yam khoom yog kub tib yam .
Vim li cas ammonia yog tub yees?
Ammonia yog ib qho ua tau zoo thiab nrov tub yees vim nws cov khoom siv hluav taws xob zoo tshaj plaws thiab tus nqi qis. Ammonia yog ib puag ncig zoo, muaj xoom GWP thiab xoom ODP. Nws yog qhov txaus ntshai thaum tso tawm ntau vim nws cov tshuaj lom .
