Chemical Properties of Oxygen
Ntawm tus qauv kub thiab siab (STP), ob lub atoms ntawm lub caij khi rau hauv daim ntawv dioxygen, tsis muaj xim, tsis muaj ntxhiab, tsis muaj roj diatomic nrog cov mis O 2 . Oxygen yog ib tug tswv cuab ntawm pawg chalcogen nyob rau hauv lub sij hawm lub sij hawm thiab yog ib tug heev reactive nonmetallic keeb.
Ntxiv mus, 2 lub cev lub cev ntawm oxygen yog dab tsi?
Lub cev muaj zog ntawm Oxygen yog raws li nram no:
- Xim: Xim tsis muaj xim.
- Phase: Gas.
- Cov ntxhiab tsw: Oxygen yog cov pa roj tsw qab.
- Saj: Ib qho roj tsw qab.
- Conductivity: Ib tug tsis zoo conductor ntawm tshav kub thiab hluav taws xob.
- Solubility: Me ntsis soluble hauv dej, cawv thiab qee cov kua dej.
- Ceev: Nws yog denser tshaj huab cua.
Dab tsi yog cov khoom nthuav dav uas muaj cov pa oxygen? Ntawm qhov qub siab , oxygen lom tshwm sim thaum cov roj ntau tshaj 50%. Cov pa oxygen tsis muaj xim, tsis muaj ntxhiab, thiab tsis qab. Nws feem ntau yog purified los ntawm fractional distillation ntawm liquefied cua, tab sis lub caij muaj nyob rau hauv ntau lub tebchaw, xws li dej, silica, thiab carbon dioxide. Cov kua thiab cov pa oxygen yog xim daj ntseg.
Ib yam li ntawd ib tug yuav nug, dab tsi yog 5 yam tshuaj lom neeg ntawm oxygen?
Chemical properties of oxygen - Kev noj qab haus huv los ntawm oxygen - Environmental teebmeem ntawm oxygen

Cov khoom ntawm oxygen thiab hydrogen yog dab tsi?
Yam ntxwv thiab Cov khoom Ntawm qhov ntsuas kub thiab siab hydrogen yog ib qho tsis muaj xim, tsis muaj ntxhiab tsw, thiab tsis muaj roj. Hydrogen yog heev flammable thiab hlawv nrog ib tug tsis pom nplaim taws. Nws hlawv thaum nws los rau hauv kev sib cuag nrog oxygen . Lub byproduct ntawm a hydrogen thiab oxygen tawg yog dej los yog H2 O.
