Basic tshuaj thaj chaw ntawm cov pa roj carbon dioxide

Ua ntej xav tias cov tshuaj thaj chaw ntawm cov pa roj carbon dioxide hais ib co ntawm cov yam ntxwv ntawm cov compound.

Txheej txheem cej luam

Carbon dioxide yog lub loj feem ntawm dej qab zib dej. Nws yog nws leej twg muab cov dej haus ib tug tshiab, sparkling. Qhov no compound yog ib tug acidic ntsev-txoj kev oxide. Tus kwv tij molecular loj ntawm cov pa roj carbon dioxide yog 44 g / mol. Qhov no gas yog hnyav dua huab cua thiab sau nyob rau hauv lub qis ib feem ntawm lub chav tsev. Qhov no compound yog tsis zoo soluble nyob rau hauv cov dej.

tshuaj zog

Cov tshuaj thaj chaw ntawm cov pa roj carbon dioxide luv luv. Nyob rau hauv kev sib cuag nrog dej lub tsim ntawm cov uas qaug zog carbonic acid. Nws yuav luag tam sim ntawd tom qab lub tsim ntawm hydrogen dissociates rau hauv cations thiab anions yog carbonate los yog bicarbonate. Cov uas ua compound yog reacted muaj tus nquag co, oxides, thiab kuj nrog alkali.

Yuav ua li cas yog qhov yooj yim tshuaj thaj chaw ntawm cov pa roj carbon dioxide? Cov tshuaj tiv thaiv sib npaug paub meej tias acidic cim ntawm lub compound. Carbon monoxide (4) yog tau tsim carbonates nrog yooj yim oxides.

lub zog

Nyob rau hauv tej yam kev mob, lub compound yog nyob rau hauv lub gaseous lub xeev. Thaum lub siab nce yuav hloov nws mus rau ib tug kua hauv lub xeev. Qhov no gas yog tsis muaj kob, ntxhiab, muaj ib tug me ntsis acidic saj. Liquefied carbon dioxide yog ib tug tsis muaj kob, pob tshab, acid-ntws, xws li cov nyob rau hauv nws cov sab nraud tsis ether los yog haus dej cawv.

Tus kwv tij molecular loj ntawm cov pa roj carbon dioxide yog 44 g / mol. Nws yog yuav luag 1.5 lub sij hawm tshaj qhov ntawd li ntawm huab cua.

Nyob rau hauv rooj plaub no tus kub yog lowered mus rau -78,5 degrees Celsius tsim ntawm qhuav dej khov. Nws yog nws hardness yog zoo li tus Cretaceous. Thaum evaporation ntawm cov tshuaj tsim los ntawm gaseous carbon oxide (4).

zoo tshuaj tiv thaiv

Thaum xav txog cov tshuaj thaj chaw ntawm carbon dioxide, nws yog tsim nyog los xaiv lub zoo teb. Nyob rau hauv cov tshuaj tiv thaiv ntawm cov tshuaj nrog txiv qaub dej (calcium hydroxide) yog tsim ib tug pos huab precipitate ntawm calcium carbonate.

Cavendish tau los xyuas xws yam ntxwv lub cev thaj chaw ntawm cov pa roj carbon monoxide (4), cov solubility nyob rau hauv dej thiab siab kev nqus.

Lavoisier twb tau soj xyuas tshuaj xyaum ua tej yam, thaum lub sij hawm uas nws sim cais tawm ib tug dawb huv hlau oxide caw txhua.

Qhia raws li ib tug ntawm xws li kev tshawb fawb thiab tshuaj thaj chaw ntawm cov pa roj carbon dioxide tau paub tseeb hais tias yuav txo tau thaj chaw ntawm lub compound. Lavoisier ignition lead oxide nrog carbon monoxide (4) tswj kom tau txais cov hlau. Nyob rau hauv thiaj li yuav xyuas kom meej tias tus thib ob cov ntaub ntawv uas yog cov pa roj carbon monoxide (4), nws yog dhau los ntawm ib tug roj txiv qaub dej.

Tag nrho cov tshuaj thaj chaw ntawm cov pa roj carbon dioxide qhia acidic cim ntawm lub compound. Lub ntiaj teb huab cua muaj cov compound nyob rau hauv txaus kom muaj nuj nqis. Nrog ib tug systematic nce nyob rau hauv lub ntiaj teb huab cua, qhov no compound tej zaum yuav ua rau loj nyab xeeb kev hloov (ntiaj teb no ua kom sov).

Uas cov pa roj carbon dioxide plays ib qho tseem ceeb luag hauj lwm nyob rau hauv cov xwm, vim hais tias cov tshuaj tau kev koom tes nyob rau hauv lub metabolism ntawm nyob hlwb. Nws yog ib yam tshuaj compound yog lub txiaj ntsim ntawm ib tug ntau yam ntawm oxidative dab txuam nrog kev ua pa uas muaj sia nyob.

Carbon dioxide muaj nyob rau hauv cov cua yog ib qho loj qhov chaw ntawm carbon rau nyob nroj tsuag. Nyob rau hauv tus txheej txheem ntawm photosynthesis (lub teeb) tshwm sim photosynthesis, uas yog nrog los ntawm cov tsim ntawm qabzib, qhov kev tso tawm ntawm oxygen nyob rau hauv cov cua.

Carbon dioxide twb tsis muaj tshuaj lom zog, nws tsis txhawb ua tsis taus pa. Thaum ntau dua ntawm cov tshuaj yeeb dej caw nyob rau hauv cov cua tshwm sim nyob rau tus neeg tuav lub ua tsis taus pa, muaj loj heev mob taub hau. Nyob rau hauv muaj sia nyob, cov pa roj carbon dioxide yog ntawm kuj zoo kawg physiological tseem ceeb, piv txwv li, nws yog tsim nyog rau cov kev cai ntawm vascular laus.

peculiarities ntawm

Nyob rau hauv industrial scale carbon dioxide yuav tau muab cais los ntawm lub flue roj. Ntxiv mus, CO2 yog ib tug byproduct ntawm lub decomposition ntawm dolomite, limestone. Niaj hnub nimno cov nroj tsuag rau zus tau tej cov carbon dioxide yuav tsum tau siv ntawm ib tug aqueous tov ntawm ethanamine adsorbing roj muaj nyob rau hauv flue roj.

Nyob rau hauv lub laboratory, cov pa roj carbon dioxide zoo tu qab tso los ntawm reacting ib carbonate los yog hydrogen nrog ib tug acid.

Cov kev siv ntawm cov pa roj carbon dioxide

Qhov no acidic oxide siv nyob rau hauv kev lag luam raws li ib tug disintegrating neeg sawv cev los yog preservative. Nyob rau cov khoom ntim, qhov no compound yog qhia raws li E290. Cov kua carbon dioxide yog siv nyob rau hauv lub tua hluav taws rau extinguishing hluav taws kub. Carbon monoxide (4) yog siv los tsim dej qab zib dej thiab ID haus.
