YOG TSIS MUAJ LI RETRIEVE ib lub raj mis ntawm sulfate Vim SULFATE ua TSIS MUAJ IB QHOV CHEMICAL COMPOUND. Sulfate yog polyatomic ion. Ib qho polyatomic ions yog hais txog pawg atoms uas nqa cov nqi. Sulfate nqa tus nqi ntawm +2.
Tsuas yog li ntawd, pawg ntawm atoms puas tuaj yeem them nqi?
A pawg atom uas muaj ib tug zoo los yog tsis zoo nqi yog hu ua polyatomic ion. Txhua ion muaj ntau cov electrons ntau dua li tag nrho cov protons hauv nws atoms . Piv txwv li, nitrite ion muaj 18 electrons thiab tag nrho ntawm 17 protons hauv nitrogen thiab oxygen atoms.
Ib tug kuj nug, dab tsi yog cov mis rau Perphosphate? Common Compounds ntawm Perphosphate PO5 -- EndMemo.
Yog li, qhov zoo sib xws thiab qhov sib txawv ntawm cov sulfate thiab sulfite ions hauv Model 1 yog dab tsi?
Ob leeg ions muaj -2 nqi, thiab txhua ion suav nrog ob qho tib si sulfur thiab oxygen atoms. Sulfate muaj plaub oxygen atoms; sulfite tsuas muaj peb.
Vim li cas polyatomic ions muaj nqi?
Qauv ntawm polyatomic ions Tom qab tau txais ib qho hluav taws xob, chloride anion muaj 17 protons thiab 18 electrons. Hauv ib polyatomic ion , pawg ntawm covalently bonded atoms nqa ib lub vas nqi vim hais tias tag nrho cov electrons nyob rau hauv lub molecule tsis sib npaug zos rau tag nrho cov protons nyob rau hauv lub molecule.

Los ntawm "encapsulating cov khoom siv hluav taws xob hauv cov pob zeb diamond," tus thawj coj tshawb fawb Tom Scott ntawm University of Bristol hais tias cov graphite tuaj yeem hloov mus ua hluav taws xob ruaj khov, tsis muaj zog heev ntawm cov roj teeb pob zeb diamond
Koj puas tuaj yeem qhia los ntawm cov kev nqus dej no seb lub teeb liab puas ua haujlwm zoo hauv kev tsav tsheb photosynthesis?
Ib qho tsis tuaj yeem qhia los ntawm daim duab no, tab sis vim tias chlorophyll ib lub teeb liab, peb tuaj yeem kwv yees tias nws yuav ua tau zoo hauv kev tsav tsheb photosynthesis. Cov xim no muaj peev xwm nqus tau ntau lub teeb ntawm lub teeb (thiab yog li ntau lub zog) dua li chlorophyll ib leeg tuaj yeem nqus tau

Txhawm rau txiav txim siab, yog koj tuaj yeem loj hlob sequoia hauv koj lub tiaj nraum qaum tsev, koj tsuas yog xav txog qhov yuav tshwm sim mus ntev rau kev tswj hwm tsob ntoo thaum nws loj heev. Giant Sequoias thiab Coast Redwoods yog cov ntoo loj tshaj plaws hauv ntiaj teb
Peb puas tuaj yeem pib lub teeb lub raj tsis muaj qhov pib?
Txhawm rau pib lub raj txias yam tsis muaj astarter yuav tsum muaj lwm txoj hauv kev ntawm kev tsim lub tshuab hluav taws xob siab, thiab txij li thaum nyob rau hauv lub raj txias cov mercury vaporhas condensed, qhov no yuav tsum muaj qhov hluav taws xob ntau dua li ua ntej. Buttonce lub raj teeb, nws sov txaus kom vaporize therest ntawm cov mercury
