Kub tooj liab hlau reacts nrog oxygen los tsim cov xim dub tooj liab oxide. Cov tooj liab oxide tuaj yeem cuam tshuam nrog cov roj hydrogen los tsim cov tooj liab hlau thiab dej. Thaum lub funnel raug tshem tawm los ntawm hydrogen kwj, lub tooj liab tseem sov txaus kom oxidized los ntawm airagain.
Tib neeg kuj nug, ua li cas thaum cov hmoov tooj liab cua sov hauv huab cua?
Thaum lub " tooj liab hmoov ”yog cua sov nyob rau hauv ib lub 'China phaj', lub tooj liab hmoov surfacebecomes coated nrog "dub xim tshuaj" vim lub formation ntawm ' tooj liab oxide 'los ntawm qhov chaw oxidation. Tooj reacts nrog oxygen nyob rau hauv lub huab cua rau cua sov thiab cov ntawv tooj liab oxide.
Puas yog tooj liab ntes hluav taws thaum rhuab? Ntxiv rau, tooj liab kab hluav taws xob ua tau tawg thaum raug rau kub , ua rau me me raug mob. Cov tooj liab explodes nrog xws li quab yuam uas txawm bystanders ua tau raug mob, raws li zoo raws li cov ncaj qha koom nyob rau hauv lub cua sov . Cov kub ntawm cov hlau ua tau ua rau nws toset hluav taws rau tsob ntoo, tsev, thiab lwm yam khoom nyob ze.
Hais txog qhov no, puas yog cua sov tooj cua hloov tshuaj los yog lub cev?
A tshuaj hloov ib txwm tsim cov khoom tshiab thiab feem ntau yog mus tas li. A hloov lub cev forms tsis muaj tshiab tshuaj thiab feem ntau yog ib ntus. Qhov no yog thaum lub compounds sib cais ua ob (los yog ntau tshaj) tshuaj. eg: tooj liab carbonate decomposes thaum cua sov tsim carbon dioxide gasand tawm dub tooj liab oxide.
Yuav ua li cas rau tooj liab thaum nws oxidizes?
Tooj , thaum raug huab cua, yuav dhau los oxidized vim muaj cov tshuaj tiv thaiv nrog oxygen. Cov tshuaj tiv thaiv tshwm sim thaum dej los yog dej noo hauv huab cua los rau hauv kev sib cuag nrog tooj liab . Ntawm no yog cov npe ntawm oxides uas tsim thaum lub sij hawm oxidation txheej txheem ntawm tooj liab rau patina.

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.

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
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
