Ceeb toom: cov pa roj ntshiab ntshiab muaj cov molecules tab sis nws tseem suav tias yog lub ntsiab lus, dua li cov khoom sib xyaw, vim cov molecules yog tsim los ntawm ib hom ntawm cov khoom.

Puas yog oxygen yog lub ntsiab lus lossis qhov sib xyaw?

oxygen (O), nonmetallic chemical element ntawm pab pawg 16 (VIa, los yog cov pa oxygen) ntawm lub sij hawm.

Yog O2 yog ib qho khoom lossis cov khoom sib xyaw lossis sib xyaw?

O₂ sawv cev rau lub molecule ntawm oxygen uas yog tsim los ntawm ob lub atoms ntawm oxygen; cov tshuaj muaj xws li ntau hom ntsiab lus piv txwv li HO. Yog li, O yog ib lub ntsiab.

Puas yog oxygen Ib qho piv txwv ntawm kev sib xyaw?

Txhua lub tebchaw yog cov molecules tab sis tsis yog txhua lub molecules yog cov khoom sib txuas. Molecular hydrogen (H2), molecular oxygen (O2) thiab molecular nitrogen (N2) tsis yog cov tebchaw vim hais tias txhua yam yog tsim los ntawm ib lub caij. Dej (H2O), carbon dioxide (CO2) thiab methane (CH4) yog cov tebchaw vim hais tias txhua yam yog tsim los ntawm ntau tshaj ib lub caij..

Na2o nqus pa oxygen?

Cov octahydrate yog tsim los ntawm kev kho sodium hydroxide nrog hydrogen peroxide. Sodium peroxide tuaj yeem npaj rau ntawm qhov loj me los ntawm cov tshuaj tiv thaiv ntawm cov hlau sodium nrog oxygen ntawm 130-200 ° C, txheej txheem uas tsim cov sodium oxide, uas nyob rau hauv ib theem absorbs oxygen: … 2 Na 2_{O + O}2 _{→ 2 Na}2_O.
