Bromine-Oxygen bonds hauv nws cov oxides siab dua yog qhov ruaj khov ntawm lwm yam Halogen-Oxides, vim tias nws tsis muaj ob qho: Ntau dua polarity xws li iodine thiab ntau daim ntawv cog lus koom nrog cov d-orbitals ib yam li cov tshuaj chlorine.
Halogen oxide yam twg ruaj khov?
Kev ruaj ntseg ntawm oxides ntawm iodine yog ntau dua li cov tshuaj chlorine thaum bromine oxides yog qhov tsawg tshaj plaws.
Vim li cas cov oxides siab dua ntawm halogens ruaj khov dua?
Vim tias cov siab dua qis dua cov qis dua thiab qhov loj ntawm cov atoms siab dua yog li lawv tsis tshua muaj zog thiab yog li cov oxides ruaj khov dua. Qhov kev sib tham no yog vim li cas cov oxides siab dua ntawm halogens zoo li ruaj khov dua cov qis dua? yog ua tiav ntawm EduRev Study Group los ntawm NEET Cov Tub Ntxhais Kawm.
Puas yog bromine reactive lossis ruaj khov?
Zoo li lwm yam halogens, bromine muaj xya electrons nyob rau hauv nws lub plhaub sab nrauv thiab is reactive heev. Koj yuav pom bromine hauv ntau cov ntsev sib xyaw nrog alkali hlau.
Qhov twg ntawm halogens ruaj khov dua?
Qhov nyiam ntawm cov ntsiab lus halogen los ua cov ntsev zoo li (piv txwv li, ionic heev) cov khoom sib xyaw ua ke nce hauv qhov kev txiav txim hauv qab no: astatine < iodine < bromine < chlorine < fluorine. Fluorides feem ntau ruaj khov dua li cov tshuaj chlorides, bromides, lossis iodides.

Vim li cas cov hlau oxides tsis yog acidic?
Thaum tsis yog xim hlau oxides sib xyaw nrog dej, nws tsim cov oxyacid ions uas yog electronegative thiab nkag tau yooj yim dissociates muab hydrogen ions, yog li acidic xwm . Vim li cas cov hlau tsis yog hu ua acidic oxides? Metallic oxide yog qhov tseem ceeb hauv cov xwm txheej vim tias thaum nws yaj hauv dej ces nws yog lub hauv paus.
Vim li cas thiaj ua rau lub sijhawm nyob ruaj khov?
Lub Sijhawm series nyob ruaj khov yog tias lawv tsis muaj qhov sib txawv lossis raws caij nyoog. Cov ntaub ntawv txheeb cais suav nrog lub sijhawm ua haujlwm zoo ib yam li lub sijhawm, zoo li qhov nruab nrab lossis qhov sib txawv ntawm qhov kev soj ntsuam.
Vim li cas tiv thaiv kev ua kom ruaj khov dua?
Raws li nws txuas ntxiv tig, nws ntsib qhov tsis zoo eclipsed conformation uas ib pawg methyl eclipses hydrogen. Raws li kev sib hloov txuas ntxiv mus, cov molecule los mus rau kev tiv thaiv conformation, uas yog qhov ruaj khov tshaj plaws vim cov neeg hloov pauv tau staggered thiab cov methyl pawg nyob deb ntawm ib leeg li sai tau Dab tsi ua rau kev sib haum xeeb ruaj khov?
Puas yog riam phom nuclear ruaj khov lossis tsis muaj kev ruaj ntseg?
Txoj kev tshawb fawb tau txiav txim siab tias thaum riam phom nuclear txhawb kev ruaj ntseg, thiab tiv thaiv kev ua tsov rog loj, lawv ib txhij tso cai rau kev tsis sib haum xeeb qis dua . Puas yog riam phom nuclear puas ncaj ncees? Kev txwv tsis pub muaj riam phom nuclear yog kev ncaj ncees rau tib neeg, kev ncaj ncees, thiab kev cai lij choj.
Muaj pes tsawg calories mucking tawm ruaj khov?
nce koj qhov kev ua si lossis tej zaum muaj ob peb ponies los txheeb tom qab 30 feeb ntawm kev tawm mus yuav ua rau muaj kev txaus siab 228 calories raug kib. Yog tias koj yog cov taum muaj zog, koj tuaj yeem hlawv txog 460 calories! Txawm li cas los xij tsuas yog tias koj tab tom ua qee qhov kev siv zog ntau dhau ib teev… tsis yog peb lub tswv yim lom zem .
