Hauv alchemy, lub cim rau tooj liab kuj yog lub cim rau lub ntiaj teb Venus. Cov ntsiab lus tuaj yeem raug cais raws li lawv lub cev lub xeev (States of Matter) e.g. gas , khoom los yog kua. Cov khoom no yog ib qho khoom. Copper yog cais raws li "Kev Hloov Hlau" uas nyob hauv Pawg 3 - 12 ntawm Lub Sij Hawm Lub Sij Hawm.
Yog li ntawd, CU puas yog ib qho khoom los yog aqueous?
Tooj Compounds Lub +1 ion muaj tetrahedral lossis square planar geometry. Hauv khov kho cov khoom xyaw, tooj liab (I) feem ntau yog lub xeev ruaj khov nyob rau nruab nrab kub. Cov tooj liab (II) ion feem ntau yog lub xeev ruaj khov dua hauv dej kev daws teeb meem.
Tsis tas li ntawd, yog tooj liab soluble los yog insoluble? Nws yog tsim nyob rau hauv ib tug loj teev los ntawm kev txo ntawm tov tooj liab oxide ore nrog tooj liab hlau los yog electrolysis ntawm aqueous tov ntawm sodium chloride siv tooj liab electrodes. Cov ntshiab compound yog insoluble hauv dej tab sis soluble nyob rau hauv hydrochloric acid los yog ammonia.
Tom qab ntawd, lo lus nug yog, yog cuno3 aqueous?
Cu(NO3 2 yog tooj liab (2) nitrate lossis cupric nitrate. Ib txwm kuaj tooj liab nitrate yog Cu(NO3 ) 2. xH2O, uas yog hydrate nrog cov dej sib txawv. Tag nrho cov ntaub ntawv no yog soluble hauv dej.
Puas yog tooj liab nyob rau hauv chav tsev kub?
Tooj yog a chemical element nrog cim Cu thiab atomic tooj 29. Classified as a kev hloov hlau, Tooj yog ib qho khoom ntawm chav tsev kub.

Dab tsi yog qhov sib npaug ionic rau cov tshuaj tiv thaiv ntawm aqueous lead II nitrate nrog aqueous sodium bromide?
Cov tshuaj tiv thaiv ntawm aqueous sodium bromide thiab aqueous lead (II) nitrate yog sawv cev los ntawm qhov sib npaug net ionic equation. 2Br−(aq)+Pb2+(aq) →PbBr2(s) 2 B r − (a q) + P b 2 + (a q) → P b B r 2 (s)
Puas yog h2s aqueous los yog khov?
Dej: H2S yog soluble hauv aqueous daws tab sis tuaj yeem tawm ntawm cov dej ntau theem lossis tsim sulfides thiab lwm cov tshuaj sulfur-muaj
Qhov twg zoo dua steel lossis tooj liab?
Hlau yog hnyav dua, thiab nws cov ductility txawv heev. Tooj liab muaj ib txwm muaj, raws li nws yog ib qho khoom, whereas steel yog ib qho alloy. 2. Cov hlau muaj zog thiab hnyav dua tooj liab, thiab ob qho tib si tuaj yeem corrode nyob rau hauv ib puag ncig ntub
Puas yog tooj liab yog ib qho nyuaj lossis soft acid?
Copper(i) tau muab cais ua ib qho khoom muag muag. Txawm li cas los xij, lub peev xwm ntawm tooj liab (i) los khi cov neeg pub dawb los yog muag muag thiab qhov sib txawv ntawm cov reactivities nthuav tawm los ntawm tooj liab (i) complexes tau tsa qee cov lus nug txog qhov xwm ntawm tooj liab (i)
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
