Thaum tshav kub ua ke, tooj liab thiab sulfur sib tov form a sulfide ntawm tooj liab . Qhov tshaj sulfur vaporizes tsim gaseous sulfur , uas khiav tawm ntawm lub crucible. Thaum kub sulfur gas ncav cuag huab cua, nws reacts nrog oxygen los tsim gaseous oxides ntawm sulfur (tseem ceeb sulfur Dioxide, SO2).
Ua raws li qhov no, puas sulfur hnov mob nrog tooj liab?
Cov tooj liab hlau reacts npaj nrog thehot sulfur gas (S8, S4 thiab S2), ua ib qho tsaus grey, nkig crystalline khoom ntawm tooj liab sulfide.
Kuj Paub, yuav ua li cas rau sulfur thaum rhuab? Ntawm cua sov cov tshuaj tiv thaiv sib tov, lub sulfur melts thiab reacts nrog cov hlau exothermically rau formiron (II) sulfide. Cov ntxhia wool ntsaws rau hauv lub qhov ncauj ntawm thetest-tube tiv thaiv sulfur vapor escaping thiab possiblycatching hluav taws.
Ib yam li ntawd, nws raug nug, vim li cas Sulfur hu ua yeeb ncuab ntawm tooj liab?
Sulfur yog paub los rhuav tshem cov metallicproperties ntawm tooj liab . Sulfur kev tawm tsam tooj liab los tsim qhov chaw dub ntawm Tooj Sulphide thiab yog li ntawd paub ' yeeb ncuab ntawm tooj '. Nyob rau hauv lub xub ntiag ntawm sulfur , tooj liab reacts nrog nws kom rov qab mus rau nws tus thawj lub xeev ntawm tooj liab sulphate uas yog lub ntuj daim ntawv ntawm tooj liab.
Puas yog tooj liab sulfide tshuaj lom?
Tooj Compounds: Feem ntau cov soluble ionizedsalts ntawm tooj liab muaj ntau ntau tshuaj lom dua li cov insoluble los yog me ntsis dissociated tebchaw. Sulfides : Sulfides ntawm cov hlau hnyav feem ntau yog insoluble thiab yog li muaj tsawg tshuaj lom kev txiav txim tshwj tsis yog los ntawm kev ywj pheej ntawm hydrogen sulfide.

Yuav ua li cas thaum koj sib tov zinc thiab iodine?
Zinc hmoov yog ntxiv rau kev daws ntawm iodine hauv ethanol. Cov tshuaj tiv thaiv exothermic redox tshwm sim, tsim zinc iodide, uas tuaj yeem tau txais los ntawm evaporating cov kuab tshuaj. Qhov kev sim tuaj yeem txuas ntxiv los qhia qhov decomposition ntawm ib qho chaw rau hauv nws cov ntsiab lus los ntawm electrolysing zinc iodide
Yuav ua li cas tshwm sim thaum aqueous tov ntawm sodium sulphate thiab barium chloride sib tov?
Thaum cov tshuaj aqueous ntawm sodium sulphate reacts nrog ib tug aqueous tov ntawm barium chloride, precipitate ntawm barium sulphate yog tsim thiab tom qab cov tshuaj tiv thaiv tshwm sim. ii. Yog hais tias cov reactants nyob rau hauv lub cev muaj zog, ces cov tshuaj tiv thaiv yuav tsis tshwm sim. Nws yog ib qho kev hloov pauv ob npaug nrog rau nag lossis daus
Yuav ua li cas tshwm sim thaum koj sib tov lead nitrate thiab sodium iodide?
Yog hais tias ob qho ntawm cov ions nyob rau hauv lub resulting sib tov sib xyaw ua ib qho insoluble compound los yog precipitate, ib qho kev tshwm sim tshwm sim. Thaum cov xim tsis muaj xim ntshiab ntawm cov hmoov lead nitrate (Pb(NO3)2) ntxiv rau cov xim tsis muaj xim ntawm sodium iodide (NaI), cov xim daj ntawm cov hmoov lead iodide (PbI2) tshwm
Yuav ua li cas thaum koj sib tov sodium chloride thiab potassium nitrate?
Yuav ua li cas sodium chloride thiab potassium nitrate teb ua ke? Yog li, koj yuav tau txais tsuas yog ib homogeneous sib tov ntawm ob ntsev, muaj cov Na +, Cl-, K + thiab NO3- ions hauv dej. Yog tias koj rhaub cov khoom sib tov ntawm ob cov ntsev, tsuas yog cov nitrate yuav decompose rau nitrite nrog cov evolution ntawm oxygen
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
