Halite muaj cleavage zoo meej thiab a tawv ntawm 2.5 ntawm Mohs tawv nplai. Limestone yog qhov ntau tshaj ntawm cov pob zeb uas tsis yog-clastic sedimentary. Limestone yog tsim los ntawm cov ntxhia calcite (calcium carbonate) thiab sediment.
Hauv qhov no, yog limestone nyuaj lossis mos?
Limestone yog a mos , yooj yim ua haujlwm pob zeb uas muaj tsawg kawg yog 50% calcite, aragonite, thiab / lossis dolomite. Pob zeb tsis muaj technically muaj cov pob zeb MOHS hardness vim lawv yog cov sib xyaw ntawm cov ntxhia.
Ib tug kuj nug, dab tsi yog limestone ntawm Mohs hardness scale? Halite muaj qhov zoo meej cleavage thiab hardness ntawm 2.5 ntawm Mohs hardness nplai. Limestone yog qhov ntau tshaj ntawm cov pob zeb uas tsis yog-clastic sedimentary. Limestone yog tsim los ntawm cov ntxhia calcite ( calcium carbonate ) thiab sediment. Lub hauv paus ntawm limestone yog limy ooze tsim nyob rau hauv dej hiav txwv.
Dab tsi yog qhov hardness ntawm fossiliferous limestone?
| Lub npe | Fossiliferous Limestone |
|---|---|
| Kev ntxhib los mos | Clastic; |
| Kev sib xyaw | Calcite |
| Xim | Lub teeb rau nruab nrab Grey |
| Lwm yam | Pom pom pob txha nyob hauv clastic matrix; Reacts nrog HCl; Hardness < iav |
Qhov kev ntxhib los mos yog limestone?
Limestone yog ib sedimentary pob zeb tsim los ntawm calcium carbonate (CaCO3), feem ntau yog calcite, qee zaum aragonite. Nws kuj tseem yuav muaj ntau ntawm magnesium carbonate (dolomite, (CaMg) (CO3)2). Feem ntau cov limestones muaj granular kev ntxhib los mos, tab sis limestone kuj tuaj yeem loj heev, crystalline lossis yas.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog hardness Yuav ua li cas txiav txim siab hardness ntawm dej?
Hardness ntawm dej yog txiav txim los ntawm titrating nrog ib tug txheej txheem tov ntawm ethylene diamine tetra acetic acid (EDTA) uas yog ib tug complexing neeg sawv cev. Txij li EDTA yog insoluble nyob rau hauv dej, disodium ntsev ntawm EDTA yog siv rau qhov kev sim no. EDTA tuaj yeem tsim plaub lossis rau rau kev sib koom tes nrog cov hlau ion
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
