Carbon dioxide
Ikhabhon dayoksayidi (carbon dioxide) yikhemikhali enefomula ye-CO2. Yenziwe ngeeathom zekhabhoni enye edityaniswe ngokuphindwe kabini kwiiathom zeoksijini ezimbini. Ifumaneka kwi-gas state kwiqondo lobushushu begumbi, kwaye njengomthombo wekhabhoni ekhoyo kumjikelo wekhabhoni, i-CO2 ye-atmospheric ngumthombo oyintloko wekhabhoni wobomi emhlabeni. Emoyeni, ikharbhon diokside ibonakala elubala ekukhanyeni okubonakalayo kodwa ifunxa imitha ye-infrared, isebenze njengegesi yegreenhouse. Ikharbon diokside iyanyibilika emanzini yaye ifumaneka kumanzi aphantsi komhlaba, kumachibi, kwimiphetho yomkhenkce nakumanzi olwandle.
