Cov khoom uas pab geologists txheeb xyuas a ntxhia nyob rau hauv lub pob zeb yog: xim, hardness, luster, siv lead ua daim ntawv, ntom, thiab cleavage. Crystal form, cleavage, thiab hardness yog txiav txim siab feem ntau los ntawm siv lead ua qauv nyob rau theem atomic. Xim thiab ntom yog txiav txim siab Feem ntau los ntawm cov tshuaj muaj pes tsawg leeg.
Yog li, dab tsi yog qhov muaj pes tsawg leeg thiab cov qauv siv lead ua ntawm cov zaub mov?
Cov ntxhia muaj tshuaj lom neeg sau ntawv , nrog cov yam ntxwv tshuaj qauv . Cov ntxhia yog cov khib nyiab uas tsim los ntawm cov txheej txheem inorganic. Tshuaj muaj pes tsawg leeg thiab crystal structure txiav txim ib cov ntxhia cov khoom, nrog rau qhov ntom, zoo, hardness, thiab xim.
Tom qab, lo lus nug yog, dab tsi yog cov qauv ntawm cov zaub mov? A ntxhia yog ib qho inorganic, crystalline khoom. A ntxhia yog tsim los ntawm cov txheej txheem ntuj tsim thiab muaj cov tshuaj muaj pes tsawg leeg. Cov ntxhia tuaj yeem txheeb xyuas los ntawm lawv cov yam ntxwv ntawm lub cev xws li crystalline qauv , hardness, streak, thiab cleavage.
Hauv qhov no, puas yog tag nrho cov ntxhia muaj cov qauv siv lead ua?
Yog lawm, tag nrho cov minerals muaj cov qauv siv lead ua , heev yooj yim vim cov ntxhia yog DEFINED raws li muaj tseeb siv lead ua qauv . Txawm li cas los xij, muaj ntau yam sib txawv uas tshwm sim los ntawm tib yam li cov ntxhia uas yog heev ntxhia -zoo li, uas tsis yog siv lead ua.
Vim li cas nws tseem ceeb kom paub cov duab ntawm cov ntxhia pob zeb muaju?
Thaum loj hlob, cov ntxhia tuaj yeem txhim kho qhov sib txawv siv lead ua daim ntawv nrog du, tiaj dav hlau hu ua siv lead ua ntsej muag. Lub geometric qauv ntawm lub siv lead ua lub ntsej muag qhia txog lub internal atomic kev npaj ntawm lub siv lead ua qauv. Qhov no yog ib qho ntawm feem ntau tseem ceeb yam hais txog a ntxhia.

Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Yuav ua li cas koj txiav txim siab lub active site ntawm ib tug enzyme?
Kev Taw Qhia. Cov chaw nquag yog cov cheeb tsam feem ntau nyob rau saum npoo ntawm cov enzymes tshwj xeeb los ntawm cov xwm txheej thaum evolution uas yog catalyze cov tshuaj tiv thaiv los yog lub luag hauj lwm rau substrate khi. Qhov chaw nquag tuaj yeem yog, yog li ntawd, muab faib ua ob ntu, uas suav nrog qhov chaw catalytic thiab substrate binding site (1)
Yuav ua li cas koj txiav txim siab qhov kawg tus cwj pwm ntawm ib tug polynomial?
Tom qab ntawd, tus coefficient ntawm lub sij hawm txhuas yuav txiav txim siab tus cwj pwm ntawm polynomial. Yog tias qhov sib txawv (cia hais tias X) yog qhov tsis zoo, ces X hauv lub sijhawm siab tshaj plaws tsim qhov tsis zoo. Peb mam li muab cov coefficient ntawm lub sij hawm coj mus rau qhov tsis zoo los txiav txim qhov kawg tus cwj pwm
Yuav ua li cas koj txiav txim siab ib tug mineral streak?
Mineral Streak Streak yog xim ntawm cov ntxhia thaum itis crushed rau hmoov. Txoj hauv kev yooj yim tshaj plaws los txiav txim siab cov pob zeb hauv av yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Minerals nrog ib tug hardness tsawg tshaj li 7 yuav tawm ib streak.

Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
