Kev tshawb nrhiav ua li cas thaum muaj kev sib tw tooj liab carbonate yog cua sov . Thaum ntsuab tooj liab carbonate {CuCO3} yog cua sov nws decomposes tsim tooj liab oxide {CuO} thiab carbon dioxide {CO2}.
Tsis tas li lo lus nug yog, Dab tsi xim yog tooj liab carbonate tig thaum rhuab?
Qee cov tebchaw tawg thaum cua sov, tsim ob lossis ntau yam khoom los ntawm ib qho reactant. Hom tshuaj tiv thaiv no hu ua thermal decomposition. Copper carbonate yog ntsuab thiab tooj liab oxide yog dub. Koj tuaj yeem pom qhov hloov xim ntawm ntsuab kom dub thaum lub sij hawm cov tshuaj tiv thaiv.
Tsis tas li ntawd, puas tooj liab carbonate decompose rhuab? Copper carbonate decomposes yooj yim rau cua sov ua tooj liab oxide thiab carbon dioxide.
Kuj tseem paub, vim li cas cua sov tooj liab carbonate yog cov tshuaj tiv thaiv decomposition?
Cov roj formula: Cu(OH) 2 Cov tshuaj tiv thaiv decomposition : Cov tshuaj tiv thaiv decomposition tshwm sim thaum kub yog siv rau cov khoom ntshiab thiab cov khoom rov ua dua rau hauv ob lossis ntau dua cov khoom tshiab. Thaum twg carbonates yog cua sov lawv tawg mus rau hauv cov hlau oxide thiab carbon dioxide, uas yog muab tawm raws li ib tug roj.
Yuav ua li cas yog tias koj noj tooj liab carbonate?
Ua phem yog nqos. Kev noj haus yuav ua rau mob plab, xeev siab, ntuav thiab raws plab. Kev noj cov khoom tuaj yeem ua rau kub hnyiab hlau, mob khaub thuas zoo li mob. Cov tsos mob ntawm cov hlau fume kub taub hau tuaj yeem ua npaws, qaug zog, ntuav, mob nqaij thiab ua tsis taus pa.

Yuav ua li cas thaum koj sib tov tooj liab thiab sulfur?
Thaum rhuab ua ke, tooj liab thiab sulfur sib xyaw ua ib qho sulfide ntawm tooj liab. Qhov ntau sulfurvaporizes tsim gaseous sulfur, uas khiav tawm ntawm lub crucible. Thaum cov roj sulfur kub ncav cuag huab cua, nws reacts nrog oxygen los tsim gaseous oxides ntawm leej faj (tsuas yog sulfur dioxide, SO2)
Yuav ua li cas rau tooj liab thaum nws rhuab?
Heated tooj liab hlau reacts nrog oxygen los tsim cov dub tooj liab oxide. Cov tooj liab oxide tuaj yeem cuam tshuam nrog cov roj hydrogen los tsim cov hlau thiab dej. Thaum lub funnel raug tshem tawm los ntawm hydrogen kwj, cov tooj liab tseem sov txaus kom oxidized los ntawm airagain
Yuav ua li cas thaum ammonium hydroxide ntxiv rau tooj liab sulphate?
Ib qho kev daws teeb meem ntawm ammonium hydroxide yog ntxiv rau cov xim xiav xiav ntawm tooj liab sulfate, ua rau lub ntsej muag xiav xiav uas tseem raug tshem tawm ze ntawm qhov chaw ntawm cov tshuaj
Yuav ua li cas thaum tooj liab oxide reacts nrog sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
