Nyob rau hauv cov nqe lus ntawm electron suav formalism, lub leej faj atom muaj oxidation lub xeev ntawm +6 thiab ib tug formal nqi ntawm 0. Cov qauv Lewis muaj S = O. doublebond thiab ob S-O dative bonds tsis siv d-orbitals. Lub sij hawm hluav taws xob dipole ntawm gaseous sulfur trioxide iszero.
Tom qab ntawd, ib tug kuj nug, dab tsi yog tus nqi rau so3?
Oxidation hais hauv SO3 (g) yog: Sulfur (+6) & Oxygen (-2), vim SO3 (g) tsis muaj nqi . Txawm li cas los xij hauv ( SO3 2 - (aq) Oxidation xeev yog: Sulfur (+4) & Oxygen (-2). Tsis txhob tau txais ob qhov tsis meej pem, lawv tuaj yeem sau tau yam tsis muaj qhov nqi , mas if SO3 yog (aq) nws yuav muaj a nqi ntawm -2.
Tsis tas li ntawd, sulfur trioxide siv rau dab tsi? Nws kuj reacts hnyav nrog qee cov hlau oxides. Sulfur trioxide tseem hu ua sulfuric oxide thiab sulfuricanhydride. Nws yog siv li ib qho nruab nrab hauv kev tsim cov sulfuric acid, lwm yam tshuaj, thiab cov khoom tawg.
Kuj paub yog, yog so3 aqueous?
sulfur trioxide ( SO3 ) feem ntau yog cov kua tsis muaj xim. Nws tuaj yeem muaj nyob hauv dej khov- lossis fiber ntau zoo li crystals lossis zoo li agas. Thaum twg SO3 yog raug rau huab cua, nws sai npaum li dej thiab muab tawm dawb fumes. Nws tuaj yeem cuam tshuam nrog dej los tsim sulfuricacid.
Puas yog 3 lub sijhawm dipole?
SO3 yog trigonal planar kom tus neeg dipoles ntawm S-O daim ntawv cog lus tshem tawm thiab cov molecule muaj tsis muaj dipole sij.

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
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
Txhais li cas los ntawm tus nqi ntws ntawm tus nqi hluav taws xob?
Ib coulomb ib ob
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
