Muaj qhov sib txawv hom ntawm chemical huab cua , qhov tseem ceeb tshaj plaws yog: Kev daws - tshem tawm pob zeb hauv daws los ntawm acidic rainwater. Inparticular, limestone yog huab cua los ntawm cov dej nag uas muaj cov kuab tshuaj CO2, (cov txheej txheem no qee zaum hu ua carbonation).
Hauv qhov no, hom huab cua yog dab tsi?
Huab cua yog qhov tawg ntawm pob zeb ntawm lub ntiaj teb nto, los ntawm kev ua dej nag, qhov kub thiab txias, thiab kev ua haujlwm lom neeg. Nws tsis koom nrog kev tshem tawm cov khoom siv pob zeb. Muaj peb hom huab cua , lub cev, tshuaj lom neeg thiab lom.
Ib tug kuj yuav nug, dab tsi yog qee qhov piv txwv ntawm cov huab cua tshuaj lom neeg? Tsib qhov piv txwv tseem ceeb ntawm cov huab cua huab cua yog oxidation, carbonation, hydrolysis, hydration thiab dehydration.
- Reacting Nrog Oxygen. Cov tshuaj tiv thaiv ntawm pob zeb thiab oxygen yog hu ua oxidation.
- Dissolving hauv Acid.
- Sib tov nrog dej.
- Absorbing dej.
- Tshem Tawm Dej.
Kuj nug, 4 hom tshuaj tiv thaiv huab cua yog dab tsi?
Kawm txog ntau hom tshuaj huab cua xws li hydrolysis, oxidation, carbonation, acid nag thiab acids tsim los ntawm lichens
- Chemical Weathering. Tej zaum koj tau pom tias tsis muaj ob lub pob zeb zoo ib yam nkaus.
- Hydrolysis. Muaj ntau hom chemicalweathering.
- Oxidation.
- Carbonation.
Chemical weathering tshwm sim sai nyob qhov twg?
Cov dej noo nrawm chemical huab cua . Huab cua tshwm sim ceev tshaj plaws hauv cov huab cua kub, ntub dej. Nws tshwm sim qeeb heev hauv huab cua kub thiab qhuav.

Cov txheej txheem ntawm kev tsim cov kev daws teeb meem yog dab tsi?
Kev daws yog tsim thaum ib yam khoom hu ua thesolute 'dissolves' rau hauv lwm yam khoom hu ua hnyav.Dissolving yog thaum lub solute tawg los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. Lawv ua qhov no los ntawm rub tawm cov ions thiab tom qab ntawd ncig cov ntsev molecules
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Vim li cas ho tsis zoo rau kev daws teeb meem los ntawm Raoult Txoj Cai?
Xav txog tib yam A thiab B Cheebtsam los tsim cov kev daws teeb meem tsis zoo, nws yuav qhia qhov tsis zoo sib txawv ntawm Raoult Txoj Cai tsuas yog thaum: Kev sib cuam tshuam ntawm cov kuab tshuaj muaj zog dua li cov kuab tshuaj thiab cov kuab tshuaj hnyav uas yog, A - B> A - A los yog B - B
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Kev sib raug zoo ntawm lub teeb thiab teeb meem yog dab tsi?
Lub teeb thiab teeb meem cuam tshuam rau ib leeg hauv ntau txoj hauv kev. Kev sib cuam tshuam ntawm lub teeb thiab teeb meem txiav txim siab qhov tshwm sim ntawm txhua yam nyob ib puag ncig peb. Lub teeb cuam tshuam nrog cov teeb meem xws li emission thiab nqus. Cov nyhuv photoelectric yog ib qho piv txwv ntawm qhov teeb meem absorbs lub teeb
