Puas yog tooj liab yog cov khoom ntshiab (vim li cas los yog vim li cas?)

Yuav tsum tau muab cais ua ib yam khoom ntshiab, ib qho khoom siv lossis cov khoom sib txuas yuav tsum muaj ib hom atom lossis molecule. Cua, dej thiab nitrogen yog cov piv txwv ntawm cov khoom ntshiab. Tab sis li cas txog tooj liab? Puas yog tooj liab yog cov khoom ntshiab?

Yog, tooj liab hlau yog ib yam khoom ntshiab. Nws tsuas muaj tooj liab atoms. Txawm li cas los xij, cov lus no tsis yog ib txwm muaj tseeb. Qee zaum tooj liab hlau tuaj yeem sib xyaw nrog lwm cov hlau. Thaum qhov no tshwm sim, peb tsis tuaj yeem faib cov hlau tooj liab ua cov khoom ntshiab.

Puas yog tooj liab yog cov khoom ntshiab (vim li cas los yog vim li cas tsis)?

Peb tuaj yeem faib cov tooj liab raws li cov khoom ntshiab uas tau hais tias cov hlau no tsuas muaj cov atoms tooj liab xwb. Ntawm no yog electron thiab proton faib ntawm tooj liab.

Vim li cas tooj liab tsis tuaj yeem dawb huv?

Raws li tau hais los saum toj no, kom ua cov khoom ntshiab, cov khoom siv lossis cov khoom sib xyaw yuav tsum muaj tsuas yog ib hom ntawm lub tsev thaiv. Nws tuaj yeem yog cov khoom xws li kub lossis cov khoom sib xyaw zoo li ntsev.

Tswv yim: Ntsev yog tsim los ntawm sodium thiab chlorine.

Txawm li cas los xij, cov ntsiab lus thiab cov tebchaw no yuav tsis muaj nyob hauv lawv daim ntawv ntshiab txhua lub sijhawm. Yog li, tooj liab tuaj yeem sib xyaw nrog lwm yam khoom. Piv txwv li, vim muaj kuab paug, tooj liab tuaj yeem sib xyaw nrog lwm yam khoom.

Txawm hais tias peb sau tooj liab ua cov khoom ntshiab, koj tuaj yeem pom cov tooj liab uas tsis yog tooj liab dawb.

Puas yog tooj liab yog lub ntsiab?

Yog lawm, nrog rau lub cim Cu, tooj liab yog ib yam khoom uas muaj cov yam ntxwv ntawm cov hlau mos thiab ductile. tooj liab yog tus lej 29 ntawm lub sijhawm teem sijhawm. Hauv cov tooj liab hlau, koj tuaj yeem pom cov atoms tooj liab xwb.

Tooj liab muaj hluav taws xob conductivity siab. Lub ntsej muag tooj liab yuav muaj xim liab-txiv kab ntxwv.

Ib yam khoom paub uas tsis tuaj yeem muab faib ua lwm yam yog hu ua lub ntsiab. Piv txwv li, oxygen yog ib yam khoom. Thiab hydrogen yog lub ntsiab. Tab sis dej tsis yog lub ntsiab lus. Dej yog tsim los ntawm oxygen thiab hydrogen atoms. Yog li ntawd, nws tuaj yeem muab faib ua ob yam sib txawv.

Puas yog tooj liab yog qhov sib xyaw?

Tsis yog, tooj liab tsis yog qhov sib xyaw. Yuav kom suav hais tias yog ib qho kev sib xyaw, ob yam khoom sib txawv yuav tsum tsim kom muaj kev sib raug zoo nrog ib leeg. Piv txwv li, carbon dioxide yog qhov sib xyaw. Nws yog tsim los ntawm carbon thiab oxygen.

Puas yog tooj liab sib xyaw?

Tsis yog, tooj liab tsis yog sib tov. Yuav tsum tau muab cais ua ib qho sib tov, lub hom phiaj tshuaj yuav tsum muaj ob los yog ntau dua cov khoom sib txawv. Txawm li cas los xij, cov tshuaj no yuav tsum muaj nyob hauv tib cheeb tsam lub cev. Tsis tas li ntawd, cov khoom yuav tsum nyob twj ywm unbound.

Tooj liab tsuas muaj ib yam khoom xwb, thiab yog li ntawd tooj liab tsis yog sib tov.

Txawm li cas los xij, qee cov khoom siv tooj liab yuav raug sau tias yog kev sib xyaw. Piv txwv li, manufacturers sib tov lwm cov hlau nrog tooj liab los hloov lawv lub cev yam ntxwv. Nov yog qee qhov piv txwv ntawm kev sib xyaw tooj liab.

• Sliding hlau (Cu - 95% thiab Zn - 5%)
• Cartridge tooj dag (Cu - 70% thiab Zn - 30%)
• Phosphor bronze (Cu - 89.75% thiab Sn - 10%, P - 0.25%)

Yog tias koj tab tom nrhiav rau ob peb lwm yam piv txwv, dej ntsev thiab dej qab zib yog cov khoom sib xyaw uas siv ntau tshaj plaws uas koj tuaj nyob rau txhua hnub.

Cov hlau tooj liab muaj dab tsi?

Feem ntau, tooj liab hlau tuaj yeem raug cais raws li cov khoom ntshiab. Nws tsuas muaj tooj liab atoms. Txawm li cas los xij, raws li tau hais ua ntej, qee cov tuam ntxhab ntxiv lwm cov hlau los hloov cov yam ntxwv ntawm lub cev ntawm cov hlau tooj liab. Cov kev hloov no yog pib los txhim kho lub zog thiab kav ntev ntawm tooj liab hlau. Cov piv txwv feem ntau yog tooj dag, titanium thiab tooj liab. Yog li ntawd, yog hais tias peb xav txog cov tooj liab hlau tag nrho, ces tooj liab hlau tsis yog ib yam khoom ntshiab.

Puas yog tooj liab hlau sib xyaw?

Nws nyob ntawm hom tooj liab hlau. Yog tias cov hlau tooj liab tsuas suav nrog cov tooj liab ntshiab xwb, peb tsis tuaj yeem xav txog cov hlau tooj liab raws li kev sib xyaw. Tab sis yog tias cov hlau tooj liab muaj lwm yam hlau, nws tuaj yeem sau npe tias yog sib xyaw.

Puas yog tooj liab hlau yog homogeneous lossis heterogeneous sib xyaw?

Ua ntej paub txog hom tooj liab hlau compound, koj yuav tsum tau nkag siab zoo dua rau ntau hom kev sib txuas. Yeej muaj ob hom kev sib tov; Homogeneous sib tov los yog heterogeneous sib tov. (1)

Homogeneous sib tov

Yog hais tias cov ntaub ntawv nyob rau hauv ib tug sib tov yog chemically homogeneous, peb hu nws ib homogeneous sib tov.

heterogeneous sib tov

Yog hais tias cov ntaub ntawv nyob rau hauv ib tug sib tov yog chemically heterogeneous, peb hu nws ib heterogeneous sib tov.

Yog li ntawd, thaum nws los txog rau tooj liab, yog tias nws tsuas muaj tooj liab, peb tuaj yeem hu nws ua homogeneous khoom. Nco ntsoov, tooj liab tsuas yog homogeneous tshuaj, tsis yog homogeneous sib tov.

Txawm li cas los xij, yog tias cov hlau tooj liab yog tsim los ntawm lwm cov hlau, qhov sib xyaw no yog homogeneous.

Nco ntsoov: Nws muaj peev xwm nrhiav tau hom tooj liab hlau uas tsis yog tshuaj lom neeg homogeneous. Qhov no yog vim muaj qhov tsis xws ntawm kev tsim khoom. Qhov no txhais tau hais tias cov hlau tooj liab tsis ua raws li cov hlau muaj zog. Tab sis, nrog rau cov cuab yeej siv niaj hnub no, nws nyuaj rau nrhiav tau cov xov tooj tooj liab.  

qhov sib txawv ntawm cov khoom ntshiab thiab sib tov

Cov khoom ntshiab tsuas muaj ib hom atom lossis ib hom molecule. Cov molecules no yuav tsum tau tsim los ntawm ib yam khoom nkaus xwb.

Yog li, raws li koj nkag siab, tooj liab tsuas muaj ib hom atom xwb, thiab qhov no yog cov khoom ntshiab.

Yuav ua li cas dej kua?

Cov dej ua kua yog tsim los ntawm oxygen thiab hydrogen atoms, thiab lawv tsim H₂O. Tsis tas li ntawd, cov dej ua kua tsuas muaj H₂Molecules O. Vim li no, kua dej yog ib yam khoom ntshiab. Tsis tas li ntawd, lub rooj ntsev, aka NaCl, yog cov khoom ntshiab. NaCl tsuas muaj sodium thiab chlorine atoms.

Tej yam uas tau tsim los ntawm ntau hom molecules lossis atoms uas tsis muaj cov qauv tsis tu ncua yog hu ua kev sib xyaw. Qhov piv txwv zoo tshaj yog vodka.

Vodka yog tsim los ntawm ethanol molecules thiab dej molecules. Cov molecules sib xyaw ua ke hauv ib qho tsis xwm yeem. Yog li, vodka yog sib tov. Salami kuj tuaj yeem raug cais raws li kev sib xyaw. Nws muaj cov rog thiab cov proteins uas muaj cov molecules sib txawv. (2)
