Lub mole yog tus nqi ntawm cov khoom ntawm ib lub cev uas muaj ntau qhov chaw hauv paus raws li muaj cov atoms hauv0.012 kilogram carbon 12; nws lub cim yog "mol". … Nco ntsoov tias lub ntsiab txhais ntawm mole yog ib yam khoom muaj nqis. Peb feem ntau yuav xa mus rau cov moles ntawm cov khoom raws li tus nqi ntawm cov khoom.
mole chemistry yooj yim txhais yog dab tsi?
mole, kuj spelled mol, hauv chemistry, ib tug qauv scientific unit rau ntsuas qhov ntau ntawm cov me me xws li atoms, molecules, los yog lwm yam particles… Lub mole yog yav tas los txhais raws li tus naj npawb ntawm atoms txiav txim siab sim kom pom nyob rau hauv 12 grams ntawm carbon-12.
1 mole yog dab tsi?
Ib mole ntawm ib yam khoom sib npaug rau 6.022 × 10²³ units ntawm cov khoom ntawd (xws li atoms, molecules, lossis ions). Tus naj npawb 6.022 × 10²³ hu ua Avogadro tus lej lossis Avogadro qhov tas li. Lub tswv yim ntawm mole tuaj yeem siv los hloov pauv ntawm huab hwm coj thiab tus lej ntawm cov khoom. Tsim los ntawm Sal Khan.
mole hauv chemistry yog dab tsi nrog piv txwv?
A mole sib raug rau qhov loj ntawm ib yam khoom uas muaj 6.023 x 10 23 cov khoom Lub mole yog chav SI rau tus nqi ntawm ib yam khoom. Nws lub cim yog mol. Los ntawm kev txhais: 1 mol ntawm carbon-12 muaj ib tug loj ntawm 12 grams thiab muaj 6.022140857 x 10 23ntawm carbon atoms (rau 10 tus lej tseem ceeb). Piv txwv.
mole hu ua dab tsi hauv chemistry?
Lub mole yog ib chav tsev siv nyob rau hauv chemistry uas yog sib npaug rau Avogadro tus lej. Nws yog tus naj npawb ntawm carbon atoms hauv 12 grams ntawm cov isotope carbon-12. Lo lus mole los ntawm lo lus molecule. Tsis muaj kev cuam tshuam rau tus tsiaj hu ua mole.

Dab tsi yog qhov tshwm sim hauv chemistry?
Cov reactivity series ntawm hlau yog daim ntawv teev cov hlau kom txo qis reactivity. Feem ntau, qhov ntau reactive ib hlau yog: qhov ntau vigorously nws reacts nrog lwm yam tshuaj. yooj yim dua nws poob electrons los tsim cov ions zoo (cations) Dab tsi yog qhov reactivity series piav nrog piv txwv?
Nyob hauv chemistry dab tsi yog tus neeg sawv cev chelate?
Chelating agents yog organic compounds muaj peev xwm txuas ua ke hlau ions los tsim cov nplhaib zoo li cov qauv hu ua chelates. Los ntawm: Phau ntawv ntawm Toxicology ntawm Kev Ua Tsov Rog Tshuaj Tshuaj, 2009 . Yuav ua li cas yog tus neeg sawv cev chelate?
Lub hauv paus hauv chemistry yog dab tsi?
base, hauv chemistry, txhua yam khoom uas nyob rau hauv cov kua dej yog nplua rau qhov kov, saj iab, hloov xim ntawm cov ntsuas(piv txwv li, tig liab litmus ntawv xiav), reacts nrog acids los tsim cov ntsev, thiab txhawb qee cov tshuaj tiv thaiv kab mob (base catalysis) .
Dab tsi ntawm cov hauv qab no txo qis los ntawm laminating lub hauv paus ntawm lub tshuab hloov pauv?
Dab tsi ntawm cov hauv qab no txo qis los ntawm laminating lub hauv paus ntawm lub tshuab hloov pauv? Hysteresis poob . Lub hom phiaj ntawm laminating cov tub ntxhais hauv lub transformer yog dab tsi? Cov tub ntxhais hlau ntawm lub tshuab hloov pauv yog laminated nrog cov ntawv nyias;
Puas yog inorganic chemistry tib yam li cov chemistry?
Tus Tswv Cuab. Yes it is same. General chemistry=inorganic chemistry and thats all that schools as for . Dab tsi yog qhov txawv ntawm inorganic chemistry thiab general chemistry? Organic, Inorganic thiab Organometallic feem ntau, cov tshuaj lom neeg muaj feem xyuam nrog cov tebchaw uas muaj cov pa roj carbon, thiab inorganic chemistry suav nrog cov tebchaw uas tsis muaj carbon atoms .
