Qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab sib xyaw yog qhov sib xyaw ua ke muaj ob lossis ntau qhov sib txuas rau ib leeg los ntawm cov tshuaj txhais tau tias qhov sib xyaw muaj ob lossis ntau qhov sib xyaw ua ke los ntawm lub cev txhais tau tias.
Ib qho sib xyaw thiab sib tov, ob qho tib si muaj ob lossis ntau yam khoom. Txawm li cas los xij, ob hom tshuaj no txawv ntawm ib leeg raws li txoj hauv kev uas cov khoom sib xyaw thiab txoj kev uas peb tuaj yeem cais cov khoom feem ntau. Ntxiv mus, cov tebchaw feem ntau yog cov tshuaj dawb huv thaum sib xyaw yog cov khoom tsis huv.
Dab tsi yog Compound?
Cov tshuaj lom neeg yog cov khoom siv ntshiab uas muaj kev sib xyaw ua ke ntawm ob lossis ntau yam tshuaj lom neeg uas khi rau ib leeg los ntawm cov txheej txheem tshuaj. Tsis zoo li ib lub caij, uas yog qhov yooj yim heev thiab yooj yim vim tias nws tsuas muaj ib qho atom thiab electrons, cov tshuaj lom neeg muaj ntau dua. Yog li ntawd, cov tshuaj formula yog txoj kev uas peb piav txog qhov complexity ntawm lub compound uas muaj ob los yog ntau tshaj atoms.
Daim duab 01: Dej Ntshiab yog tshuaj lom neeg
Muaj ntau hom tshuaj tiv thaiv uas tuaj yeem tsim cov khoom sib txuas: ionic bonds, uas tsim cov ntsev, covalent bonds, uas tsim cov molecular compounds thiab metallic bonds, uas tsim inter-metallic compounds. Nyob ntawm qhov kub uas peb siv los tsim lawv, cov tshuaj lom neeg tuaj yeem siv rau hauv cov khoom khib nyiab, kua lossis roj. Qee qhov piv txwv ntawm cov khoom sib xyaw ua ke yog cov ntsev thiab dej.
Kev sib tov yog dab tsi?
Ib qho sib tov yog cov khoom tsis huv uas muaj ob lossis ntau yam khoom. Tsis zoo li ib qho kev sib xyaw, qhov sib tov tsis muaj qhov sib xyaw ua ke tas li; Ntxiv mus, peb tuaj yeem tsim lossis cais cov kev sib xyaw ntawm lub cev. Li no nws tsis xav tau cov txheej txheem tshuaj. Yog li ntawd, tus kheej ntawm txhua yam khoom nyob rau hauv ib tug sib tov khaws cia thiab tsis hloov.
Daim duab 02: Cov kua dej ntxuav tais diav yog ib qho sib xyaw
Tsis tas li ntawd, muaj ob hom kev sib tov. Lawv yog; homogeneous thiab heterogeneous sib tov. Thiab tseem, peb tuaj yeem faib cov khoom sib xyaw ua ke raws li ib qho ntawm cov hauv qab no: alloy (kev sib xyaw ua ke ntawm ib lossis ntau lub ntsiab lus), kev ncua (cov kua dej uas muaj cov khoom me me) lossis colloids. Piv txwv ntawm qee cov khoom sib xyaw hauv tsev muaj xws li mis nyuj thiab kua ntxuav tais diav.
Dab tsi yog qhov sib txawv ntawm Compound thiab Mixture?
Cov tshuaj lom neeg yog cov khoom siv ntshiab uas muaj kev sib xyaw ua ke ntawm ob lossis ntau yam tshuaj lom neeg thaum sib xyaw yog cov khoom tsis huv uas muaj ob lossis ntau yam khoom. Yog li, qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab kev sib xyaw yog qhov sib xyaw ua ke muaj ob lossis ntau qhov sib xyaw ua ke los ntawm cov tshuaj siv tshuaj thaum sib xyaw muaj ob lossis ntau qhov sib xyaw ua ke los ntawm kev siv lub cev. Lwm qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab sib xyaw yog tias, tsis zoo li cov khoom sib xyaw, peb tuaj yeem cais cov khoom sib xyaw yooj yim thiab lawv cais rau hauv lawv cov khoom sib xyaw. Thaum faib cov tebchaw, peb xav tau ntau lub zog los ua cov txheej txheem tshuaj lom neeg, thaum nyob rau hauv kev sib xyaw tsuas yog yuav tsum muaj peev xwm txiav txim siab seb yuav cais lawv li cas ntawm lawv qhov ntom, solubility thiab loj.
Cov hauv qab no qhia cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm qhov sib xyaw thiab sib xyaw.
Summary – Compound vs Mixture
Txawm hais tias muaj kev sib koom ua ke, cov khoom sib xyaw (cov khoom siv ntshiab) thiab cov khoom sib xyaw (cov khoom tsis huv) txawv ntawm qhov sib xyaw lossis sib cais. Yog li, qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab sib xyaw yog qhov sib xyaw ua ke muaj ob lossis ntau qhov sib txuas ua ke los ntawm kev siv tshuaj lom neeg. Thaum qhov sib tov muaj ob lossis ntau qhov sib xyaw ua ke los ntawm kev siv lub cev. Nws kuj tseem nthuav kom nco ntsoov tias lawv muaj ntau npaum li cas hauv peb lub neej txhua hnub. Raws li nws hloov tawm, muaj ntau yam sib xyaws thiab cov khoom sib xyaw uas peb haus thiab siv ua zaub mov, ntxuav cov cuab yeej thiab lwm yam.
