hlau oxide

Tsis tas li ntawd, cov tshuaj tiv thaiv ntawm hlau thiab oxygen yog dab tsi?

Rust yog tsim thaum hlau reacts nrog oxygen nyob rau hauv cov huab cua noo. Cov kev sib npaug tshuaj hauv qab no sawv cev rau tshuaj tiv thaiv : 4Fe + 3O2 → 2Fe2O3. Dej yog tsim nyog rau oxidation tshuaj tiv thaiv tshwm sim thiab kom yooj yim thauj cov electrons.

Ib tug kuj yuav nug, puas muaj hlau nyob rau hauv oxygen? Hlau yog ib qho tseem ceeb rau kev tsim cov ntshav. Kwv yees li 70 feem pua ntawm koj lub cev hlau muaj nyob rau hauv tus Cov qe ntshav liab ntawm koj cov ntshav hu ua hemoglobin thiab hauv cov leeg hlwb hu ua myoglobin. Hemoglobin yog qhov tseem ceeb rau kev hloov pauv oxygen hauv koj cov ntshav los ntawm tus lub ntsws rau tus cov ntaub so ntswg.

Ib tug kuj yuav nug, yog hlau thiab oxygen yog cov tshuaj tiv thaiv combustion?

Nws yog ib qho piv txwv ntawm kev tsim tshuaj tiv thaiv , ib redox tshuaj tiv thaiv , thiab a combustion tshuaj tiv thaiv . Hlau combusts hauv oxygen tsim ntau yam hlau oxides, feem ntau hlau (III) oxide: 4 Fe (s) + 3 O 2 (g) ==> 2 Fe 2O 3 (s) Hlau nyob rau hauv nws ib txwm bulk daim ntawv yuav tsuas hlawv thaum nyob rau hauv ntshiab oxygen nrog thaum tshav kub kub txaus.

Cov tshuaj tiv thaiv dab tsi yog xeb?
