Qhov Tseem Ceeb Qhov txawv - Isomorphism vs Polymorphism
Cov tshuaj muaj peev xwm muaj nyob hauv ntau hom kev sib txawv. Cov ntaub ntawv sib txawv no tuaj yeem sib txawv morphologies lossis cov qauv sib txawv. Cov qauv ntawm cov tshuaj sib xyaw ua ke txiav txim siab lub cev lub cev ntawm cov khoom sib xyaw. Qee zaum cov khoom siv tshuaj lom neeg kuj raug txiav txim los ntawm cov qauv. "Morphism" yog ib lo lus siv rau lub npe lub sij hawm "morphology". Nws piav txog cov tsos sab nraud ntawm ib qho kev sib txuas. Cov ntsiab lus isomorphism thiab polymorphism yog siv los piav txog cov tsos mob sab nraud. Polymorphism txhais tau hais tias muaj ib qho chaw nyob hauv ntau tshaj ib daim ntawv crystalline. Isomorphism yog qhov muaj nyob ntawm ob lossis ntau lub tebchaw uas muaj tib lub morphology. Qhov sib txawv tseem ceeb ntawm isomorphism thiab polymorphism yog tias isomorphism yog hais txog qhov muaj ob lossis ntau lub tebchaw nrog cov morphologies zoo tib yam thaum polymorphism hais txog qhov sib txawv ntawm cov morphologies ntawm tib yam khoom.
Isomorphism yog dab tsi?
Isomorphism hais txog qhov muaj ob lossis ntau qhov sib xyaw nrog cov morphologies zoo tib yam. Qhov no txhais tau hais tias lub hav zoov ntawm tib cov qauv siv lead ua nyob rau hauv cov tebchaw sib txawv. Cov tshuaj no yog hu ua isomorphous tshuaj. Cov tshuaj isomorphous muaj ze li qhov zoo ib yam thiab cov qauv.
Cov tebchaw no muaj qhov sib piv ntawm cov atoms tam sim no hauv cov tebchaw. Qhov no qhia tau hais tias cov qauv empirical ntawm cov tshuaj isomorphous zoo ib yam. Tab sis lub cev lub cev ntawm cov tshuaj isomorphous yog qhov sib txawv ntawm ib leeg vim tias lawv muaj cov atomic sib txawv. Piv txwv li: huab hwm coj, ntom, tshuaj reactivity yog qee yam ntawm lub cev muaj zog uas txawv ntawm cov tshuaj isomorphous. Cia peb xav txog qee qhov piv txwv kom nkag siab tias isomorphism hauv chemistry yog dab tsi.
Calcium carbonate (CaCO3) thiab sodium nitrate (NaNO3).
Daim duab 01: Kev Sib piv ntawm Calcium Carbonate thiab Sodium Nitrate as Isomorphous Substances
Ob leeg calcium carbonate thiab sodium nitrate yog trigonal hauv cov duab. Qhov sib piv atomic ntawm cov atoms tam sim no hauv txhua qhov sib xyaw yog 1: 1: 3. Tab sis cov tebchaw no muaj lub cev thiab tshuaj lom neeg sib txawv. Lawv cov molar pawg kuj txawv ntawm ib leeg (Calcium carbonate=100g / mol thiab sodium nitrate=85 g / mol).
Sodium phosphate (Na 3PO4) thiab sodium arsenate (Na3AsO 4).
Cov tebchaw no muaj nyob hauv cov duab tetrahedral, thiab cov qauv ntawm cov tshuaj no muaj qhov sib piv atomic 3: 1: 4. Tab sis lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv.
YPolymorphism yog dab tsi?
Polymorphism yog hais txog qhov muaj qhov sib txawv ntawm cov morphologies ntawm tib yam khoom. Cov khoom uas qhia tau hais tias polymorphism yog hu ua polymorphic tshuaj. Ntawm no, ib qho kev sib xyaw muaj nyob hauv cov duab sib txawv thiab cov ntaub ntawv crystalline.
Polymorphic tshuaj qhia qhov zoo sib xws thiab qhov sib txawv raws li cov qauv. Tab sis feem ntau ntawm cov sij hawm, cov khoom siv tshuaj yog tib yam vim nws yog tib lub compound uas muaj nyob rau hauv ntau hom. Tab sis lub cev muaj zog txawv., CaCO3 (calcium carbonate) muaj nyob hauv daim ntawv orthorhombic lossis hauv daim ntawv hexagonal.
Daim duab 02: Allotropes ntawm Carbon
Allotropy yog ib lo lus cuam tshuam rau polymorphism. Allotropy yog hais txog polymorphism ntawm ib lub caij. Cov tebchaw uas qhia txog allotropy yog hu ua allotropes. Allotropes tshwm sim thaum lub caij tsim cov qauv crystalline nrog kev sib txawv. Piv txwv li carbon daim ntawv allotropes xws li pob zeb diamond lossis graphite. Cov allotropes no muaj cov tshuaj lom neeg thiab lub cev sib txawv.
Qhov txawv ntawm Isomorphism thiab Polymorphism yog dab tsi?

Summary – Isomorphism vs Polymorphism
Isomorphism thiab polymorphism qhia ob lub tswv yim sib txawv. Qhov sib txawv ntawm isomorphism thiab polymorphism yog tias isomorphism hais txog qhov muaj ob lossis ntau lub tebchaw nrog cov morphologies zoo tib yam whereas polymorphism hais txog qhov sib txawv ntawm cov morphologies ntawm tib yam khoom.
