Teb
- Teb.
- kev 15.
- HIO = Hypoiodous acid; IO-=Hypoiodite. HIO2 = iodous acid; IO2 = iod. HIO3 = iodic acid; IO3 = iod. HIO4 = Periodic acid; IO4-= lub sij hawm.
- Nyem qhia rau lwm tus paub, nws yuav pab tau li cas.
Tsis tas li ntawd, oxyanion yog dab tsi muab ob qho piv txwv?
Piv txwv Oxyanion Nitrate (NO3-), Nitrite (NO 2 -), sulfite (SO3 2 -thiab hypochlorite (ClO-) yog tag nrho oxyanions.
Tsis tas li ntawd, dab tsi yog qhov xaus lus thaum tsis muaj oxygen atoms hauv cov mis? Cov-ate lus yog siv rau feem ntau oxyanion (xws li sulfate SO42- los yog nitrate TSIS MUAJ 3-). Qhov-ib lus yog siv rau ntawm oxyanion nrog ib oxygen atom tsawg dua (xws li sulfite SO32- los yog nitrite TSIS MUAJ 2-). Qee zaum nyob ntawd tuaj yeem yog hypo-prefix, lub ntsiab lus ib oxygen atom tsawg dua rau-ite.
Kuj tseem paub yog, oxyanion yog dab tsi thiab nws lub npe li cas?
Qee lub ntsiab lus tuaj yeem tsim ntau dua ib qho oxyanion ua (polyatomic ions uas muaj cov pa oxygen), txhua tus muaj cov lej sib txawv ntawm cov pa oxygen. Lub anion nrog ib qho ntxiv oxygen atom tshaj li (hauv paus) noj anion yog npe los ntawm kev muab per- ntawm qhov pib ntawm lub hauv paus thiab - noj thaum kawg.
Po3 npe hu li cas?
PO 3 3- yog hu ua Phosphite. Ib qho phosphite hauv inorganic chemistry yog ntsev ntawm phosphorous acid, H3PO3 thiab ua raws li IUPAC naming cov lus pom zoo phosphite ion yuav yog. PO 3 - 3, ntsev ntawm P (OH) 3. Keeb kwm phosphite tau xa mus rau cov ntsev uas muaj HPO2-

Plaub hom kev nyob deb nroog yog dab tsi?
R.L. Singh pom plaub yam tseem ceeb: (i) compact settlements, (ii) semi-compact or hemleted cluster, (iii) semi-sprinkled or fragmented or hamleted settlements and (iv) sprinkled or dispersed type. Raws li tus naj npawb ntawm cov zos, hamlets thiab tus naj npawb ntawm cov neeg nyob, R.B. Singh tau txheeb xyuas plaub qhov chaw nyob
Plaub hom xov tooj cua sib tham yog dab tsi?
Cov ntsiab lus 2.1 Uranium-lead dating method. 2.2 Samarium-neodymium yos txoj kev. 2.3 Potassium-argon dating method. 2.4 Rubidium-strontium yos txoj kev. 2.5 Uranium-thorium yos txoj kev. 2.6 Radiocarbon dating method. 2.7 Fission taug kev sib tam txoj kev. 2.8 Chlorine-36 dating method
Plaub hom polymers yog dab tsi?
Muaj plaub yam yooj yim ntawm biomacromolecules: carbohydrates, lipids, proteins, thiab nucleic acids.Cov polymers no yog tsim los ntawm cov monomers sib txawv thiab ua haujlwm sib txawv. Carbohydrates: molecules tsim los ntawm qab zib monomers. Lawv tsim nyog rau kev khaws cia hluav taws xob
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Qhov twg ntawm cov plaub hau plaub hau yog ib txwm plaub hau plaub hau?
square Tsis tas li ntawd nug, qhov ntsuas ntawm ib lub quadrilateral tsis tu ncua yog dab tsi? Yog, sab hauv lub kaum sab xis ntawm txhua lub ces kaum ntawm ib lub quadrilateral tsis tu ncua yog txhua 90 degrees (360 degrees / 4 fab).
