Basic chemical izakhiwo-carbon dioxide

Ngaphambi kokucabangela le nezakhi ezithile zamakhemikhali-carbon dioxide hlandla nye of izici kwakwakhe.

Uhlolojikelele

Carbon dioxide iyona isici esiyinhloko sokulawula amanzi soda. Nguye onika isiphuzo fresh, elikhazimulayo. Le ngxube kuyinto azibukhali oxide usawoti-ukwakha. Isihlobo mass yamangqamuzana -carbon dioxide 44 g / Mol. Lokhu igesi ngoyisiwula kusinda kunakho emoyeni futhi iqoqa engxenyeni engezansi egumbini. Le ngxube kuyinto kabi oncibilikayo emanzini.

chemical izakhiwo

I chemical izakhiwo-carbon dioxide kafushane. Ukuxhumana amanzi ukwakheka ababuthakathaka carbonic acid. It cishe ngokushesha ngemva kokwakhiwa hydrogen dissociates ku cations futhi anions kukhona carbonate noma Bicarbonate. Egcekeni kwaphumela is wasithukuthelela insimbi asebenzayo, oxides nangamalungu alikhali.

Yiziphi eziyisisekelo chemical izakhiwo-carbon dioxide? Ukusabela zibalo uqinisekise uhlamvu azibukhali kwakwakhe. I-carbon monoxide (4) uyakwazi ukwakha carbonates nge oxides eziyisisekelo.

izakhiwo

Ngaphansi kwezimo ezivamile, kwakwakhe lisasesimweni gaseous. Lapho ukwanda Ingcindezi ingakhula ibe ulithumele isimo uketshezi. Lokhu igesi Ayinambala, ayinaphunga, kunobuciko okuncane ene-asidi. Liquefied carbon dioxide kuyinto kungekho nto enemibala emihle, okusobala, acid-fudlana ezifanayo imingcele yangaphandle yayo ether noma utshwala.

Isihlobo mass yamangqamuzana-carbon dioxide 44 g / Mol. Kuyinto cishe 1.5 izikhathi obukhulu kunobukaJohane emoyeni.

Uma kwenzeka izinga lokushisa sehliselwe -78,5 degrees Celsius kumiswa iqhwa. He is ubulukhuni bayo kufana Cretaceous. Phezu ukuhwamuka we izinto ezakhiwe gaseous carbon oxide (4).

ukuphendula qualitative

Lapho uhlola nezakhi ezithile zamakhemikhali-carbon dioxide, kubalulekile ukukhetha impendulo qualitative. Ngo ukusabela chemical ngamanzi lime (calcium hydroxide) Kumiswa a kwenze esinamafu-calcium carbonate.

Cavendish bakwazi ukuthola izakhiwo ezinjalo isici ngokomzimba we-carbon monoxide (4), solubility ngamanzi okusezingeni eliphezulu gravity ethize.

Lavoisier lwenziwe experiment zamakhemikhali, lapho yena wazama ukuhlukanisa oxide metal okumsulwa iwayini ngamunye.

Ukhombe ngenxa izifundo ezinjalo nezakhi ezithile zamakhemikhali-carbon dioxide isikuqinisekisile ukunciphisa izakhiwo egcekeni. Lavoisier ukuthungela phambili oxide ne-carbon monoxide (4) uphatha ukuthola metal. Ukuze uqinisekise ukuthi into yesibili i-carbon monoxide (4), it is idlule emanzini igesi lime.

Zonke izakhiwo chemical-carbon dioxide kuqinisekisa uhlamvu azibukhali kwakwakhe. emkhathini iqukethe kwakwakhe Ubuningi obanele. Nge ukukhuphuka ehlelekile emkhathini woMhlaba, le kwakwakhe kungadala sina ukuguquka kwesimo sezulu (ukufudumala kwembulunga yonke).

Lokho-carbon dioxide linendima ebalulekile emvelweni, ngoba amakhemikhali iye bahileleke umzimba izinhlayiya zamangqamuzana aphilayo. Kuyinto kwakwakhe chemical kuwumphumela ezihlukahlukene oxidative izinqubo ezihlobene ne emishinini yokuphefumula yezinto eziphilayo.

Carbon dioxide eziqukethwe kulo moya ozungeze umhlaba umthombo enkulu carbon izitshalo ophilayo. Ngo inqubo ye-photosynthesis (ukukhanya) kwenzeka inqubo ye-photosynthesis, okuyinto kuhambisana kumiswa glucose, ukukhululwa oksijini emkhathini.

Carbon dioxide akanazakhiwo anobuthi, ayisekeli ukuphefumula. Ngezinye lokuhlala ephakeme we ketshezi emkhathini kwenzeka umuntu ubambe umoya, kukhona zekhanda ezinamandla. Ngo eziphilayo, i-dioxide carbon kubaluleke kakhulu bokuphila, isibonelo, kubalulekile ukulawulwa ithoni semithambo.

izici of

Ngo isikali zezimboni carbon dioxide kungenziwa uhlukane igesi flue. Ngaphezu kwalokho, CO2 kuyinto eceleni we yokubola dolomite, namathempeli ngokhonkolo namatshe. izitshalo Modern ukwenziwa carbon dioxide ezidinga ukusetshenziswa ikhambi aqueous of ethanamine adsorbing igesi eziqukethwe igesi flue.

Endaweni yokucwaninga, i-dioxide carbon zibuyiswe ukusabela a carbonate noma i-hydrogen ne-acid.

Ukusetshenziswa kwe-carbon dioxide

Lokhu oxide esidi elisetshenziswa umkhakha njenge-ejenti uwohloka noma uyalondoloza. On womkhiqizo, lokhu kwakwakhe kuboniswa njengoba E290. Lolu ketshezi carbon dioxide isetshenziswa mlilo ukuze zokucisha imililo. I-carbon monoxide (4) isetshenziswa ukukhiqiza amanzi soda lemonade isiphuzo.
