Ntau lawm. Potassium oxide yog tsim los ntawm cov tshuaj tiv thaiv ntawm oxygen thiab poov tshuaj ; qhov tshuaj tiv thaiv no muaj peev xwm poov tshuaj peroxide, K2O2. Kev kho mob ntawm peroxide nrog poov tshuaj tsim cov oxide : K2O2 + 2 K → 2 K2O.
Hauv qhov no, cov poov tshuaj oxide tsim li cas?
Potassium oxide yog ib qho ionic compound tsim los ntawm kev sib txuas poov tshuaj thiab oxygen. Nws nqa cov tshuaj formula K2O. Potassium nrhiav tsis tau dawb vim nws yog reactive heev. Nws muaj valency +1 thiab sib txuas nrog cov pa oxygen atoms tsim K2O.
Puas yog potassium oxide yog lub hauv paus? Basic oxides -Nws yog ib tug complex tshuaj oxides , uas tsim cov ntsev nrog tshuaj lom neeg cov tshuaj tiv thaiv nrog acids los yog acidic oxides thiab tsis hnov mob nrog hauv paus los yog yooj yim oxides . Piv txwv li, qhov yooj yim oxides suav nrog cov hauv qab no: K2O ( poov tshuaj oxide ), CaO (calcium oxide ), FeO (hlau oxide 2- zoo).
Tom qab ntawd, cov poov tshuaj oxide siv rau dab tsi?
Txog Potassium Oxide Potassium Oxide yog ib tug heev insoluble thermally ruaj khov Potassium qhov chaw haum rau iav, optic thiab ceramic daim ntaub ntawv. Oxide compounds tsis conductive rau hluav taws xob.
Qhov sib npaug ntawm cov poov tshuaj oxide yog dab tsi?
Teb thiab piav qhia: Cov tshuaj formula rau potassium oxide yog K2 O , txhais tau tias cov molecule yog ua los ntawm ob lub poov tshuaj atoms thiab ib tug oxygen atom.

Yog vim li cas sodium poov tshuaj twj tso kua mis active thauj?
Lub twj tso kua mis sodium-potassium yog ib qho piv txwv ntawm kev thauj mus los vim tias lub zog yuav tsum tau txav cov sodium thiab potassium ions tawm tsam qhov concentration gradient. Lub zog siv los roj lub twj tso kua mis sodium-potassium los ntawm kev tawg ntawm ATP rau ADP + P + Zog
Yuav ua li cas thaum barium chloride reacts nrog poov tshuaj sulfate?
Thaum barium chloride reacts nrog potassium sulfate, barium sulfate thiab potassium chloride arc tsim. Qhov sib npaug sib npaug rau cov tshuaj tiv thaiv no yog: BaCl_2(aq) + K_2SO_4(aq) rightarrow BaSO_4(s) + 2KCl(aq) Yog tias 2 moles ntawm poov tshuaj sulfate react, Cov tshuaj tiv thaiv noj moles ntawm barium chloride
Yuav ua li cas ib tug crystal ntawm alum txawv ntawm ib tug crystal ntawm poov tshuaj sulfate?
A) Teb yog: potassium aluminium sulfate yog siv lead ua nrog cubic qauv, potassium aluminium sulfate dodecahydrate (alum) yog hydrate (muaj dej los yog nws cov ntsiab lus)
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Yuav ua li cas koj ua foob pob ua ntxaij roj nrog poov tshuaj nitrate?
Siv cov nplai, ntsuas 14 grams ntawm potassiumnitrate los yog saltpeter (KNO3) thiab 7 grams qab zib.Qhov no ua kom txaus propellant rau ib qho 2'-ntev rocketmotor. Muab cov khoom xyaw los ntawm muab tso rau hauv ib lub thawv yas nruj nreem kaw nrog ib txhais tes ntawm cov hlau lead nuv ntses loj lossis. 50-caliber lead pob
