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?
oxidation
Pom zoo:
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Hom tshuaj tiv thaiv dab tsi yog bh3?
Cov tshuaj formula: BH3
Dab tsi yog qhov sib txawv tseem ceeb ntawm tshuaj lom neeg thiab cov tshuaj tiv thaiv nuclear Lub hlwb?
(1) Cov tshuaj tiv thaiv Nuclear cuam tshuam nrog kev hloov pauv ntawm inan atom lub nucleus, feem ntau tsim cov khoom sib txawv, nrog rau kev tawm ntawm cov hluav taws xob xws liα, β thiab gamma; lwm ray. Cov tshuaj tiv thaiv tshuaj, ntawm qhov tod tes, tsuas yog muaj kev hloov pauv ntawm cov hluav taws xob thiab tsis cuam tshuam nrog kev hloov pauv hauv cov nuclei
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
