Cov qauv rau sodium zincate yog Na2ZnO2. Thaum peb ntxiv ib co sodium hydroxide rau daim zinc hlau ces sov nws a ntsev yog tsim namely, sodium zincate hydrogen gas tso tawm.
Tsis tas li cov lus nug yog, dab tsi yog cov mis rau sodium zincate?
H4Na2O4Zn
Ib tug kuj yuav nug, dab tsi yog lub xeev ntawm sodium zincate? Cov mis ntawm Sodium Zincate yog Na2ZnO2. Peb tuaj yeem tau txais Sodium Zincate Thaum peb sib tov qee cov zinc granules hauv sodium hydroxide. Ib tug compound yog tsim nrog hydrogen gas. Qhov sib xyaw uas tau tso rau hauv peb lub thawv hauv aqueous xeev.
Raws li qhov no, yuav ua li cas sodium zincate tsim?
Txais Cov Lus Teb: Thaum lub hauv paus reacts nrog ib tug hlau, ces cov hlau ntsev thiab hydrogen gas yog tsim . Thaum twg sodium hydroxide tov yog rhuab nrog zinc, ces sodium zincate thiab hydrogen gas tsim.
Dab tsi yog Valency ntawm Zincate?
Sodium Zincate yog tsim los ntawm Sodium cation (Na +) thiab Zincate anion (ZnO2-2), yog li, muab cov tshuaj formula ntawm Na2ZnO2. Ntawm no, zincate anion muaj valency 2.

Cov kev hloov ntawm lub cev txawv ntawm cov tshuaj hloov pauv li cas muab ib qho piv txwv ntawm txhua tus?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
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
Thaum muab piv cov qauv sau rau ib tus neeg raug liam cov ntaub ntawv lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub tshaj kaum ob lub hlis?
Thaum piv cov qauv sau rau tus neeg raug liam? cov ntaub ntawv, lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub ntau tshaj rau rau kaum ob lub hlis. Tus lej txaus ntawm tus qauv yog qhov tseem ceeb rau kev txiav txim siab qhov tshwm sim ntawm kev sib piv
Yuav ua li cas tshwm sim thaum koj muab cov khoom them nqi ze ntawm Electroscope thiab vim li cas?
Hauv cov txheej txheem induction ntawm kev them nyiaj, ib qho khoom them raug coj los ze rau tab sis tsis kov lub electroscope. Qhov no tau piav qhia los ntawm cov kev them nqi zoo li lub hauv paus ntsiab lus. Lub zais pa uas tsis zoo tiv thaiv cov hluav taws xob tsis zoo, yog li yuam kom lawv txav mus los
