Carbon dioxide, physico-yawo yamakhemikhali izakhiwo kanye nokubaluleka kwamasiko

Carbon dioxide, noma Silica - igama omqondofana eyaziwa kahle -carbon dioxide. Ngokusho ngezigaba kwamakhemikhali, izidakamizwa - carbon oxide (IV), CO _2. Ngaphansi kwezimo ezivamile, kwakwakhe lisasesimweni gaseous, Ayinambala futhi ayinaphunga, kodwa has a ukunambitheka omuncu. Oncibilikayo emanzini, ukwakha carbonic (carbonate acid). Isici-carbon dioxide wukuthi ngesikhathi ingcindezi evamile asemkhathini (101325 Pa noma 760 mm HG. V.) Akukho esimweni liquid, kodwa kuphela ngesimo igesi noma okuthiwa iqhwa elomile. Lolu ketshezi carbon dioxide kungenzeka kuphela uma ingcindezi umfutho. Kuleli fomu kungashiwo uthuthwa amasilinda futhi esetshenziselwa nezinye izinjongo: kwabashiselayo, ukukhiqizwa uphuzo carbonated, umnkantsha futhi iyapholisa imikhiqizo ukudla nasezintweni zokucima umlilo. Le nto usetshenziselwa ukuvimbela ukubola kokudla kanye no-E 290, a disintegrant kanye refrigerant for the test.

Carbon dioxide - nitrous esidi, ngakho-ke kungaba asabela nge oxides eziyisisekelo futhi alkalies, kanjalo zakha isimiso usawoti - carbonates noma bicarbonates, namanzi. ukuphendula qualitative ukucacisa CO ₂ ukuxhumana yayo nge -calcium hydroxide. Ukuba khona kwalesi igesi izobonisa turbidity yesixazululo futhi kwenze. Ezinye ane-alikhali futhi ane-alikhali emhlabeni izinsimbi (umsebenzi) ungafaka ngaphansi kwesimo-carbon dioxide, wayencisha ke umoya-mpilo. Futhi, dioxide carbon engena ukusabela ikhemikhali esikhundleni futhi ngaphezu izakhi organic.

Senzeka nemvelo futhi ayingxenye ye-imvilophu umoya womhlaba. Imvelo ahlukanisa eziphilayo bokuphefumula, futhi izitshalo ukukuqonda e-photosynthesis futhi lisetshenziswe izinqubo bokuphila kwamakhemikhali.

Ngenxa okusezingeni eliphezulu ukushisa umthamo wayo, uma kuqhathaniswa nezinye yamagesi asemkhathini, uglikisly igesi lapho lokuhlushwa imvelo kubangela okweqile yayo, ngenxa aphansi ukushabalalisa ukushisa emkhathini. A ukunyuka kwezinga lokushisa kuholela ukuncibilika kwezinguzunga zeqhwa , futhi ngenxa yokushintsha kwesimo sezulu emhlabeni jikelele. Ososayensi balinganisela futhi waphetha ngokuthi isinqumo yale nkinga (ekulweni kwamagesi abamba ukushisa emkhathini) kungasiza izitshalo eziluhlaza, ekwazi ukuncela CO2 okuningi kuka manje ziphonswe.

Naphezu kweqiniso lokuthi isikhutha ehilelekile umzimba zezitshalo nezilwane, anda nokuqukethwe kwalo emkhathini kungabangela ukozela, ubuthakathaka, ikhanda, ngisho umoya. Ukuze ugweme hypercapnia kuyadingeka ukuze pholisa igumbi, ikakhulukazi ezindaweni ibuthelele inani elikhulu labantu.

Ngakho, i-carbon dioxide - kuyinto oxide acid ukuthi yendalo futhi liwumkhiqizo umzimba yezimila nezilwane ezihlukahlukene. ekuqongeleleni yayo kulo moya ozungeze umhlaba inhlamvu kwamagesi abamba ukushisa emkhathini. Carbon dioxide ukusabela ngamanzi lwakha carbonic acid engazinzile uyakwazi uwohloka emanzini kanye CO2.
