Koj tuaj yeem txheeb xyuas cov khoom tsis paub zoo li cas?
- Thaum twg koj tuaj yeem ntsib nrog tsis paub tshuaj nyob hauv lub ntiaj teb tiag?
- Kev sim yooj yim koj tuaj yeem ua tau.
- Cov txheej txheem chromatographic.
- Spectroscopic txoj kev.
- X-ray crystallography (x-ray diffraction, lossis XRD)
- Loj spectrometry.
Tom qab ntawd, ib tug kuj yuav nug, ua li cas koj txheeb xyuas cov khoom?
Lub cev muaj zog yog cov uas tuaj yeem txiav txim siab lossis ntsuas yam tsis tau hloov pauv qhov muaj pes tsawg leeg lossis tus kheej ntawm tus kheej yam khoom . Cov khoom no muaj xws li xim, tsw, saj, ntom, melting point, boiling point, conductivity, thiab hardness.
Ib yam li ntawd, koj tuaj yeem txheeb xyuas cov kua tsis paub li cas? Rau txheeb xyuas ib tug ntshiab ua kua Cov khoom siv lub cev muaj zog ntawm solubility, ntom, thiab boiling point. Cov khoom ntawm lub cev ntawm cov khoom ntshiab tuaj yeem ntsuas yam tsis hloov qhov muaj pes tsawg leeg ntawm cov khoom. Hauv qhov kev sim no koj yuav kawm cov tswv yim rau kev txiav txim solubility, ceev, thiab boiling point.
Yog li ntawd, koj yuav ua li cas kuaj cov tshuaj tsis paub?
Hauv nag lossis daus, koj tuaj yeem ntxiv ib tshuaj mus rau ib qho kev daws teeb meem thiab saib seb cov ntaub ntawv precipitate. Acid / puag kuaj yuav qhia koj cov pH ntawm cov khoom thiab seb nws yog cov kua qaub, lub hauv paus lossis cov khoom nruab nrab. nplaim taws kuaj yog siv los txheeb xyuas cov ions raws li cov xim uas cov nplaim taws tawm.
Yuav siv qhov ntom ntom los txheeb xyuas cov khoom tsis paub?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub los ntawm kev ntsuas nws ceev thiab muab koj cov txiaj ntsig sib piv rau cov npe uas paub ceev . Qhov ntom = loj / ntim. Xav tias koj yuav tsum tau txheeb xyuas qhov tsis paub hlau. Koj faib cov huab hwm coj los ntawm lub ntim thiab muab piv rau ceev mus rau ib daim ntawv uas paub ceev.

Koj puas tuaj yeem txheeb xyuas lub luag haujlwm uas cov neeg tsim khoom ua si hauv lub voj voog carbon?
Cov neeg tsim khoom, cov neeg siv khoom, thiab cov decomposers ua lub luag haujlwm hauv lub voj voog carbon? ~ Cov neeg tsim khoom tsim lawv cov khoom noj los ntawm kev ua kom zoo nkauj siv lub zog los ntawm lub hnub ci thiab carbon dioxide los ntawm huab cua. Lawv ua pa rov qab carbon dioxide rau hauv qhov chaw. Cov neeg siv khoom siv cov khoom noj uas tsim los ntawm cov neeg tsim khoom rau lub zog
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Koj tuaj yeem txheeb xyuas cov hlau li cas los ntawm kev ntsuas nplaim taws?
Chemists siv tib lub hauv paus ntsiab lus los txiav txim seb tus kheej ntawm cov hlau tsis paub siv qhov ntsuas nplaim taws. Thaum kuaj nplaim hluav taws, chemists coj ib qho hlau tsis paub thiab muab tso rau hauv qab nplaim taws. Cov nplaim taws yuav tig xim sib txawv raws li cov hlau nyob hauv cov khoom. Cov kws tshawb fawb tuaj yeem txheeb xyuas lawv cov khoom tsis paub
Koj puas tuaj yeem txheeb xyuas cov ntxhia los ntawm ib qho khoom xwb?
Koj tuaj yeem txheeb xyuas cov ntxhia los ntawm nws cov tsos thiab lwm yam khoom. Cov xim thiab luster piav txog cov tsos ntawm cov ntxhia, thiab streak piav txog cov xim ntawm cov hmoov ntxhia. Mohs hardness scale yog siv los sib piv cov hardness ntawm minerals
Puas yog qhov ceev yog ib txoj kev txhim khu kev qha ntawm kev txheeb xyuas tag nrho cov khoom tsis paub?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub los ntawm kev ntsuas nws qhov ntom thiab sib piv koj cov txiaj ntsig rau cov npe paub qhov ntom ntom. Qhov ntom = loj / ntim. Xav tias koj yuav tsum txheeb xyuas cov hlau tsis paub. Koj tuaj yeem txiav txim siab qhov loj ntawm cov hlau ntawm qhov ntsuas
