Thaum koj muab ib daim ntawm aluminium nyob rau hauv acid kom tshem tawm cov oxide txheej. Tshem tawm thiab muab tso rau hauv acetone thiab tom qab ntawd ether. Koj yuav rau ib lub sij hawm luv heev pom ntshiab Aluminium . Nws yog electropositive heev thiab yuav hnov mob nrog oxygen sai heev rau daim ntawv Aluminium oxide.

Tsuas yog li ntawd, thaum txhuas thiab oxygen muab cov qauv?

Qhov no txhais tau hais tias cov tshuaj formula rau aluminium oxide tsuas yog Al2 O3. Ntawd yog 2 aluminium atoms rau txhua txhua 3 oxygen atoms.

Ib sab saum toj no, Aluminium teb li cas nrog huab cua? Cov tshuaj tiv thaiv ntawm aluminium nrog cua Aluminium reacts nrog oxygen, tsim cov txheej txheem tiv thaiv ntawm alumnium (III) oxide uas tiv thaiv ntxiv tshuaj tiv thaiv nrog oxygen. Zoo li magnesium, aluminium burns nyob rau hauv oxygen nrog ib tug ci ntsa iab nplaim dawb. Cov khoom hauv qhov no tshuaj tiv thaiv tseem yog alumnium (III) oxide.

Kuj Paub, yuav ua li cas thaum Aluminium reacts nrog chlorine?

Thaum twg aluminium hlau los ntawm kev sib cuag nrog tshuaj chlorine gas nyob rau hauv muaj cua sov, tsausmuag tshuaj tiv thaiv pib thiab Aluminium chloride hmoov / granule cov ntaub ntawv. Qhov no yog ib qho exothermic tshuaj tiv thaiv . Tom qab pib lub tshuaj tiv thaiv thiab vim exothermic tshuaj tiv thaiv kub siab pab hauv nws pib tshuaj tiv thaiv nyob rau hauv-nruab nrab aluminium thiab Chlorine.

Yuav ua li cas thaum koj sib tov oxygen thiab poov tshuaj?

Potassium oxide yog tsim los ntawm cov tshuaj tiv thaiv ntawm oxygen thiab poov tshuaj ; qhov tshuaj tiv thaiv no muaj peev xwm poov tshuaj peroxide, K2O2. Potassium hydroxide tsis tuaj yeem ua kom lub cev qhuav dej ntxiv rau cov oxide tab sis nws tuaj yeem hnov mob nrog molten poov tshuaj los tsim nws, tso hydrogen raws li ib tug byproduct.
