Helium, neon, thiab argon yeej tsis tau pom los tsim cov tebchaw nrog oxygen, txawm tias nyob rau hauv qhov xwm txheej hnyav. Qhov hnyav dua cov pa roj - krypton, xenon, thiab radon - tuaj yeem yaum kom muaj kev sib raug zoo nrog oxygen, tab sis lawv tsis ua li ntawd raws li tus qauv txheej txheem.
Ntawm no, lub ntsiab lus twg tsis hnov mob nrog oxygen ncaj qha?
Platinum
Tsis tas li ntawd, puas yog tag nrho cov hlau puas muaj oxygen? Cov hlau reacts nrog oxygen ua form hlau oxides. Cov no hlau oxides yog qhov tseem ceeb hauv qhov xwm txheej. Magnesium oxide yaj hauv dej los tsim magnesium hydroxide tov. Magnesium hydroxide hloov liab litmus rau xiav uas qhia tau hais tias magnesium oxide yog ib qho yooj yim oxide.
Yog li ntawd, cov hlau twg tsis hnov mob nrog oxygen?
Ob hlau uas tsis hnov mob nrog oxygen yog nyiaj thiab kub . Lawv tsis hnov mob nrog oxygen txawm nyob rau qhov kub thiab txias.
Tsis hnov mob nrog oxygen thaum rhuab?
Cov tshuaj tiv thaiv Ntawm Cov Hlau nrog Cua Lawv nkaus xwb teb nruab nrab txawm tias thaum yog cua sov muaj zog. Qee cov hlau yog heev inert (??) thiab tsis txhob hnov qab nrog cua / oxygen nyob rau hauv tag nrho txawm nyob rau hauv heev muaj zog cua sov . Cov qauv ntawm reactivity muab cov Hlau Reactivity Series (?????).

Vim li cas beryllium tsis hnov mob nrog hydrogen?
Beryllium tsis hnov mob ncaj qha nrog hydrogen tsis zoo li lwm yam alkaline ntiaj teb hlau los tsim ionic hydride. Qhov no yog vim oxidation peev xwm ntawm beryllium tsawg heev thiab yog li nws tsis pub nws cov electrons yooj yim rau hydrogen
Vim li cas qhov loj ntawm magnesium nce thaum nws hnov mob nrog oxygen?
Thaum cov magnesium yog cua sov, tag nrho cov huab hwm coj nce vim magnesium reacts nrog oxygen, tsim magnesium oxide (yog li nws txhawb qhov kev xav). Qhov hnyav nce yog vim muaj oxygen
Puas yog KMnO4 hnov mob nrog alkanes?
Thaum cov xim liab ntawm cov oxidizing tus neeg sawv cev KMnO4 ntxiv rau alkene, alkene yog oxidized rau diol thiab KMnO4 hloov mus rau xim av MnO2. Alkanes thiab aromatic tebchaw tsis hnov mob nrog poov tshuaj permanganate
