xeb yog lwm lub npe rau hlau oxide, uas tshwm sim thaum hlau los yog hlau alloy uas muaj hlau, zoo li hlau, raug oxygen thiab ya raws rau lub sij hawm ntev. Nyob rau tib lub sijhawm, cov pa oxygen ua ke nrog cov hlau ntawm qib atomic, tsim cov khoom siv tshiab hu ua oxide thiab ua rau cov hlau tsis muaj zog.
Ib yam li ib tug yuav nug, dab tsi yog qhov ua rau xeb?
Kev xeb yog ua rau los ntawm oxidization ntawm cov hlau hauv cov hlau tsim hlau oxide. Qhov no feem ntau yog ua rau thaum muaj dej noo thiab oxygen.
Tsis tas li ntawd, dab tsi yog qhov ua rau xeb ntawm peb lub tsheb? Feem ntau, xeb , los yog oxidation ntawm hlau, tshwm sim thaum cov hlau raug hlau, oxygen, los yog dej. Cov tshuaj tiv thaiv ntawm cov hlau thiab hlau, oxygen lossis dej tawg, lossis oxidizes, hlau ua rau qhov tsos ntawm xeb . Cov feem ntau ua rau xeb ntawm tsheb yog nthuav cov hlau rau dej.
Tom qab ntawd, lo lus nug yog, rusts sai npaum li cas?
Cov hlau tshiab raug rau qhov cua kub uas muaj oxygen thiab dej ntau daim ntawv ib txheej nyias ntawm xeb tam sim ntawd (tab sis yog tias koj saib lub sijhawm luv luv tom qab nthuav tawm cov hlau nto, koj yuav muaj qhov tsawg heev. xeb ).
Puas yog xeb sib xyaw?
Cov lus teb ceev yog: Pob zeb diamond yog cov khoom ntshiab, carbon; kub yog ib yam khoom ntshiab, kub; thiab xeb yog ib tug compound, Iron Oxide, ntawm hlau thiab Oxygen. xeb yog ib tug compound: Iron Oxide.
Pom zoo:
Cov khoom dab tsi tuaj yeem xeb?
Cov hlau twg yuav tsim xeb? Hlau. Hlau yuav xeb sai heev. Yog tias hlau raug tso cai kom ntub thiab raug huab cua pom xim av xeb tuaj yeem txhim kho hauv ob peb teev xwb. Aluminium. Aluminium kuj tseem mined tawm hauv av raws li oxidized compound hu ua Bauxite. Tooj. Tooj liab rusts los ntawm nws cov xim hlau ntuj xim av ntxoov ntxoo mus rau ib tug kaj ntsuab
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
Dab tsi ua rau cov npuas tsim thaum koj ntxiv cov hydrochloric acid rau zinc hlau?
Mercuric oxide. Mercury hlau. Thaum zincreacts nrog hydrochloric acid, cov tshuaj tiv thaiv bubblesvigorously li hydrogen gas yog tsim. Thaum zinc reacts nrog hydrochloric acid, lub raj kuaj ua kom sov asenergy yog tso tawm thaum lub sij hawm cov tshuaj tiv thaiv
Dab tsi yog qhov ua rau ntuj tsim ua rau nce qib co2 hauv lub voj voog carbon?
Cov pa roj carbon dioxide ntxiv rau hauv qhov chaw ib txwm muaj thaum cov kab mob ua pa los yog decompose (kev lwj), carbonate pob zeb raug huab cua, hluav taws kub hav zoov tshwm sim, thiab hluav taws kub tawg. Cov pa roj carbon dioxide kuj ntxiv rau cov huab cua los ntawm tib neeg kev ua ub no, xws li kev hlawv cov fossil fuels thiab hav zoov thiab kev tsim cov cement
