Carbon dioxide. Izakhiwo, ukukhiqizwa, isicelo

Carbon dioxide - into ine sebuningini zezihloko: i-carbon monoxide (IV), carbon dioxide noma-carbon dioxide. Njengoba futhi ibizwa nangokuthi i-carbon anhydride. He is ngokuphelele igesi kungenambala ukuthi ayinaphunga, nge ukunambitheka omuncu. Carbon dioxide ngoyisiwula kusinda kunakho emoyeni futhi kabi oncibilikayo emanzini. Emazingeni ngezansi - 78 ° C esitheni futhi uyofana iqhwa.

Kusukela isimo gaseous ke ludlulele ketshezi okuqinile, ngoba asikwazi khona isimo uketshezi at umfutho womoya. I kwabantu ka-carbon dioxide ngaphansi kwezimo ezivamile ka 1,97 kg / M3 - izikhathi 1.5 kwabantu emoyeni. Carbon dioxide ngefomu okuqinile ibizwa ngokuthi "iqhwa". Enkulumweni ketshezi, lapho singasetshenziswa ligcinwe isikhathi eside, ke uqhubeka nenqubo ingcindezi enkulu. Ake sicabangele izidakamizwa futhi yayo isakhiwo sazo sekhemikhali.

Carbon dioxide, ogama Ifomula CO2, yakhiwa yekhabhoni nomoya-mpilo, futhi etholakale ngenxa yokushisa noma abolile izinto eziningi eziphilayo. I-carbon monoxide eziqukethwe emoyeni, komhlaba umthombo amaminerali. Abantu nezilwane futhi ikhiphe i-carbon dioxide ngesikhathi umoya air. ngaphandle ukukhanyisa izitshalo ihlaba umkhosi, futhi uye wakwenza ngokuzimisela ubamba ngesikhathi i-photosynthesis. Ngokusebenzisa inqubo umzimba amaseli wabo bonke abahlala nezidalwa carbon monoxide ingenye yezingxenye esemqoka kwemvelo.

Lokhu igesi akuyona anobuthi, kodwa uma aqoqana lokuhlala eliphezulu, usungaqala kokuziklinya (hypercapnia), futhi ngaleso ukuntula kwayo ekuthuthukiseni isimo okuphambene - hypocapnia. Carbon dioxide okuhambisa imisebe ultraviolet futhi ibonisa infrared. Uyena Igesi ebamba ukushisa, esithinta ngqo ukufudumala kwembulunga yonke. Lokhu kungenxa yokuthi ezingeni saba of wo contents lukhula emkhathini, futhi kubangela Isivuvu.

Carbon dioxide ibhalwe ngokuphakeme ezimbonini kusukela amagesi Smoky noma esithandweni, noma i-yokubola carbonates kanye dolomite namathempeli ngokhonkolo namatshe. Ingxube lezi amagesi ekhethekile wageza ngokucophelela nge isixazululo of potassium carbonate. Ngaphezu kwalokho, kwathi ingena hydrogen ne ubola lapho evuthayo, lapho-carbon dioxide ikhishwe. kwakhiwa Carbonic acid (H2CO3) is kusuka carbon dioxide ziyoncibilika emanzini, kodwa etholwe izimo zamanje kanye nezinye izindlela ezithuthukile kunalezi. Ngemva carbon dioxide kususwa, it is onomfutho, selehlile futhi akhishwa phakathi amasilinda.

Ngo umkhakha, le nto kabanzi futhi evame ukusetshenziswa. abasebenzi umkhakha Ukudla uyisebenzisa njengendlela disintegrator (isib nomkhombe), noma njengoba uyakulondoloza (E290). Ngosizo carbon dioxide ukukhiqiza ehlukene tonic iziphuzo kanye soda, okuyinto ngakho abathandwa hhayi kuphela izingane kodwa futhi abadala. Carbon dioxide isetshenziswa womshini baking soda, ubhiya, ushukela, iwayini bubbly.

Carbon dioxide lisetshenzisiwe nangokuqondene womshini mlilo ngempumelelo. Ukusebenzisa i-carbon dioxide elakhiwe naphakathi esebenzayo edingekayo lapho Welding wire. At igesi lokushisa eliphezulu carbon arc ubola kube umoya-mpilo ne-carbon monoxide. Oxygen ixubana metal liquid oxidize ke. Carbon dioxide cartridges isetshenziswa emoyeni ngezibhamu ngesibhamu.

Model izindiza ukusebenzisa lolu ketshezi njengoba yokubasela onobuhle zabo. Ukusebenzisa i-carbon dioxide kungaba ngokuphawulekayo ngcono ezithela izitshalo etshalwa kule abamba ukushisa. Futhi kule mboni kabanzi iqhwa yikuphi ukudla kuyagcinwa ngcono kakhulu. Isetshenziselwa njengoba refrigerant e amafriji, nokuqondisayo, ugesi kagesi, kanye nezinye izitshalo amandla ezishisayo.
