A) Teb yog: poov tshuaj aluminium sulfate yog siv lead ua nrog kub qauv, poov tshuaj aluminium sulfate dodecahydrate ( alum ) yog hydrate (muaj dej los yog nws cov ntsiab lus).
Ua li no, vim li cas Alum thiaj li ua cov muaju?
tshwm sim vim hais tias raws li kev daws teeb meem, qee cov dej ua kua yuav maj mam evaporate ntawm qhov chaw xws li txav mus rau hauv huab cua raws li cov dej vapor (gas). Qhov no txhais tau hais tias muaj dej tsawg dhau los tuav tag nrho cov yaj alum thiab ib co ntawm cov alum particles yuav tsum tawm los ntawm cov tshuaj raws li khoom.
Qhov thib ob, cov duab ntawm alum siv lead ua yog dab tsi? OCTAHEDRAL
Ib yam li ntawd ib tug yuav nug, ua li cas koj thiaj li tau txais poov tshuaj los ntawm Aluminium sulphate crystals?
Alum crystals Ob tbsp. ntawm alum yog tov nrog 1/2 khob dej thiab rhaub rau ntawm qhov cub los yog hauv lub microwave kom txog thaum lub alum yog yaj tag. Ncuav rau hauv ib lub tais uas muaj kuab heev, kub-pov thawj thiab cia zaum rau 24 teev. Tus kheej siv lead ua yuav daim ntawv uas yog ces muab tshem tawm los ntawm kev loj hlob ntau heev tov.
Nws siv ntau npaum li cas alum los ua crystals?
Alum crystals yog cov uas yooj yim thiab ceev tshaj plaws siv lead ua koj tuaj yeem loj hlob. Tsuas yog sib tov 1/2 khob dej kub heev nrog 2-1/2 tablespoons ntawm alum . Koj tuaj yeem tau txais alum los ntawm cov txuj lom ntawm lub khw muag khoom noj los yog nrog cov kaus poom thiab cov khoom siv pickling. Cov siv lead ua kev loj hlob yuav pom tom qab ob peb feeb.

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
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
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 yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
