Qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab kev daws yog qhov sib xyaw muaj ob lossis ntau lub ntsiab lus uas muaj tshuaj lom neeg ua ke thaum cov tshuaj muaj ob peb yam tshuaj uas tsis muaj tshuaj lom neeg ua ke ua ke.
Cov tshuaj thiab cov tshuaj yog cov sib xyaw ntawm cov ntsiab lus lossis lwm cov khoom sib xyaw. Cov ntsiab lus ib leeg tsis tshua ruaj khov nyob rau hauv tej yam ntuj tso. Lawv tsim ntau yam kev sib txuas ntawm lawv lossis nrog lwm cov ntsiab lus kom muaj nyob. Thaum qhov no tshwm sim, cov khoom ntawm ib lub ntsiab sib txawv thiab ua rau muaj kev sib xyaw tshiab-rau-tshiab.
Dab tsi yog Compound?
Compounds yog ib yam tshuaj uas muaj ob los yog ntau tshaj cov tshuaj sib txawv. Txawm li cas los xij, peb tsis xav txog kev sib xyaw ua ke ntawm ob lossis ntau dua ntawm tib yam tshuaj lom neeg ua ke; lawv yog cov molecules, tsis sib txuas. Piv txwv li, diatomic molecules zoo li O2, H2, N2 lossis polyatomic molecules zoo li P 4 tsis yog cov tebchaw, tab sis lawv yog cov molecules. Qee qhov piv txwv ntawm cov sib xyaw ua ke yog NaCl, H2O, HNO3, thiab C6H 12O6
Daim duab 01: Ib qho Molecule muaj ntau dua ib qho tshuaj lom neeg yog cov khoom sib xyaw
Yog li ntawd, cov tebchaw yog ib pawg ntawm cov molecules; Yog li, tag nrho cov tebchaw yog molecules, tab sis tsis yog tag nrho cov molecules yog cov tebchaw. Cov ntsiab lus nyob rau hauv ib qho kev sib txuas nrog ib leeg ntawm covalent bonds, ionic bonds, metallic bonds, thiab lwm yam. Cov qauv ntawm cov compound muab tus naj npawb ntawm atoms nyob rau hauv lub compound thiab lawv ratios. Nyob rau hauv ib qho kev sib xyaw, cov ntsiab lus muaj nyob rau hauv ib qho kev faib ua feem. Peb tuaj yeem pom cov ntsiab lus no yooj yim los ntawm kev saib cov tshuaj formula ntawm ib qho chaw sib xyaw. Ntxiv mus, cov tebchaw ruaj khov, thiab lawv muaj cov yam ntxwv zoo, xim, khoom, thiab lwm yam.
Kev daws yog dab tsi?
Ib tshuaj yog ib homogeneous sib tov ntawm ob los yog ntau yam tshuaj. Peb hu nws homogenous sib tov vim hais tias muaj pes tsawg leeg yog uniform thoob plaws hauv cov tshuaj. Lub Cheebtsam ntawm kev daws yog feem ntau ntawm ob hom solutes thiab cov kuab tshuaj. Cov kuab tshuaj dissolves lub solutes thiab tsim ib tug uniform tov. Yog li ntawd, feem ntau cov kuab tshuaj yog siab tshaj qhov solute kom muaj nuj nqis.
Daim duab 02: Kev daws teeb meem sib txawv
Tsis tas li ntawd, tag nrho cov khoom hauv cov tshuaj muaj qhov loj ntawm cov molecule lossis ib qho ion. Yog li, peb tsis tuaj yeem saib lawv ntawm qhov muag liab qab. Tsis tas li ntawd, cov kev daws teeb meem tuaj yeem muaj xim yog tias cov kuab tshuaj los yog cov kuab tshuaj tuaj yeem nqus pom lub teeb. Txawm li cas los xij, cov kev daws teeb meem feem ntau yog pob tshab.
Ntxiv mus, cov khoom sib xyaw no tuaj yeem tshwm sim hauv cov kua, gaseous lossis cov khoom muaj zog. Tab sis, feem ntau cov kuab tshuaj yog kua. Tsis tas li ntawd, ntawm cov kua, peb suav tias dej yog cov kuab tshuaj thoob ntiaj teb, vim tias nws tuaj yeem yaj ntau yam ntau dua li lwm cov kuab tshuaj. Tsis tas li ntawd, peb tuaj yeem yaj cov roj, cov khoom siv los yog lwm yam kua hauv cov kua ua kua. Txawm li cas los xij, hauv cov kuab tshuaj roj, tsuas yog cov kua roj ntsha yuav yaj.
Muaj qhov txwv ntawm cov kuab tshuaj uas peb tuaj yeem ntxiv rau qee yam ntawm cov kuab tshuaj. Thaum nws ncav cuag qhov siab tshaj plaws, cov tshuaj yuav saturated. Tab sis, yog hais tias tus nqi ntawm solute yog tsawg heev, cov tshuaj yuav diluted. Yog hais tias muaj ntau cov kuab tshuaj nyob rau hauv cov tshuaj, nws yog ib tug concentrated tov. Los ntawm kev ntsuas qhov concentration ntawm cov tshuaj, peb tuaj yeem tau txais ib lub tswv yim hais txog tus nqi ntawm cov kuab tshuaj hauv cov tshuaj.
Dab tsi yog qhov sib txawv ntawm Compound thiab tshuaj?
Cov tshuaj yog cov tshuaj uas muaj ob lossis ntau dua cov tshuaj sib txawv sib koom ua ke. Txawm li cas los xij, kev daws teeb meem yog homogeneous sib xyaw ntawm ob lossis ntau yam tshuaj. Yog li, qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab kev daws yog qhov sib xyaw ua ke muaj ob lossis ntau lub ntsiab lus uas muaj tshuaj lom neeg ua ke thaum cov tshuaj muaj ob peb yam tshuaj uas tsis muaj tshuaj lom neeg ua ke ua ke.
Ntxiv mus, nyob rau hauv ib qho kev sib xyaw, cov ntsiab lus muaj nyob rau hauv ib qho piv txwv, tab sis nyob rau hauv ib qho kev daws, cov khoom hauv nws yuav tsum tsis tas yuav muaj nyob rau hauv qhov tseeb. Tsis tas li ntawd, lwm qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab kev daws yog tias peb tuaj yeem cais cov khoom sib xyaw hauv cov tshuaj los ntawm kev siv tshuaj thiab lub cev, tab sis peb tuaj yeem cais cov khoom sib xyaw hauv ib qho chaw los ntawm cov tshuaj txhais tau tias tsuas yog.
Cov hauv qab no infographic ntawm qhov sib txawv ntawm qhov sib xyaw thiab cov tshuaj muab cov ntsiab lus ntxiv ntawm qhov sib txawv no.
Summary – Compound vs Solution
Cov tshuaj thiab cov kev daws teeb meem yog sib xyaw ntawm cov tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab kev daws yog qhov sib xyaw ua ke muaj ob lossis ntau lub ntsiab lus uas muaj tshuaj lom neeg ua ke thaum cov tshuaj muaj ob peb yam tshuaj uas tsis muaj tshuaj lom neeg ua ke ua ke.
