Xim dab tsi oxygen hlawv?
Koj tau txais blue cov pa taws nrog cov pa roj carbon monoxide thaum koj muaj pa txaus rau kev sib xyaw kom tiav. Thaum koj muaj oxygen txaus, cov nplaim taws tshwm xiav vim tias kev sib xyaw ua tiav tsim lub zog txaus los ua kom txaus siab thiab ionize cov roj molecules hauv nplaim taws.
oxygen ua li cas thaum hlawv?
Hluav taws siv oxygen thaum nws hlawv. Tab sis nws kuj tsim carbon dioxide. Cov pa oxygen molecule muaj ob lub pa oxygen atom hauv nws. Cov hluav taws siv qhov no los tsim cov pa roj carbon dioxide los ntawm kev ntxiv ib qho carbon atom los ntawm hluav taws cov roj (ntoo, piv txwv li).
