Thaum KClO3 yog cua sov muaj zog, nws tawg, tso pa oxygen thiab tawm hauv qab lub thermally ruaj khov (piv txwv li, kub -insensitive) cov khoom seem ntawm cov ionic potassium compound. Muaj tsawg kawg yog peb qhov plausible tshwm sim ib qho ua tau sau rau tus txheej txheem, tab sis tsuas yog ib qho tshwm sim rau txhua qhov tseem ceeb.
Yog li ntawd, yuav ua li cas thaum KClO3 rhuab?
Thaum cov poov tshuaj chlorate ( KClO3) yog rhuab Nyob rau hauv lub xub ntiag ntawm manganese dioxide catalyst, nws decomposes tsim poov tshuaj chloride thiab oxygen gas.
Ib sab saum toj, dab tsi yog qhov decomposition ntawm KClO3? Lub thermal decomposition ntawm poov tshuaj chlorate los tsim cov poov tshuaj chloride thiab oxygen. Cov tshuaj tiv thaiv no tshwm sim ntawm qhov kub ntawm 150-300 ° C. Hauv cov tshuaj tiv thaiv no, cov catalyst tuaj yeem yog manganese (IV) oxide.
Ib yam li ntawd, thaum cov khoom poov tshuaj chlorate rhuab nws puas decompose?
Nrog ntxiv cua sov , poov tshuaj perchlorate decomposes rau poov tshuaj chloride thiab oxygen: KClO4 → KCl + 2 O. Kev nyab xeeb ntawm cov tshuaj tiv thaiv no yuav tsum muaj cov reagents ntshiab heev thiab ceev faj tswj kub.
Puas yog qhov decomposition ntawm KClO3 yog cov tshuaj tiv thaiv redox?
Decomposition ntawm poov tshuaj chlorate yog ib qho piv txwv ntawm tshuaj tiv thaiv redox.

Yuav ua li cas tshwm sim rau kev daws qhov concentration thaum nws rhuab?
Yuav ua li cas tshwm sim rau qhov saturation concentration thaum ib tug tov lub temp yog nce. Yuav ua li cas tshwm sim raws li ib tug tov yog rhuab? Yog tias koj ua kom sov ib yam khoom ntau dua koj lub taub hau nws cov suab thaj ntau dua tam sim no lub solubility yuav siab dua, thaum rhuab vim nws yuav siv sij hawm ntau dua rau cov khoom kom saturated.

Thaum twg cov khoom yog rhuab thiab hloov mus rau hauv cov kua nws?
Yog tias dej khov (ib qho khoom) tau rhaub nws hloov mus rau dej (kua kua). Qhov kev hloov no hu ua MELTING. Yog hais tias dej yog rhuab, nws hloov mus rau chav (gas). Qhov kev hloov no hu ua BOILING
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
Thaum boric acid h3bo3 yog rhuab ntawm 140 C nws tsim?
Tshaj 140 ° C, boric acid lossis lwm hom metaboric acid hloov mus rau cubic metaboric acid
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
