Cov tshuaj mos crystalline thiab cov nrog cov atom loj duanyiam muaj ntau dua entropies vim muaj zog molecular zog thiab teeb meem. Ib yam li ntawd, qhov tseeb entropy ntawm ib yam khoom zoo li nce nrog nce molecular complexity vim hais tias tus naj npawb ntawm cov muaj microstates nce nrog molecular complexity.
Puas entropy nce nrog tus lej ntawm cov molecules?
Entropy feem ntau nce hauv cov tshuaj tiv thaiv uas tag nrho cov khoom lag luam molecules yog ntau dua li tag nrho cov reactant molecules. Ib qho kev zam rau txoj cai no yog thaum cov roj tau tsim los ntawm cov tshuaj tsis muaj zog.
Pob molecules lossis atoms muaj ntau entropy?
Rau ib yam khoom, Ssolid < Sliquid < Sgas hauv ib muab lub cev lub cev ntawm qhov kub thiab txias, entropy feem ntau ntau dua rau cov atoms hnyav dua lossis ntau dua cov molecules.
Yuav ua li cas thiaj muaj qhov nce siab dua?
Entropy yog ib qho kev ntsuas ntawm randomness lossis tsis meej pem hauv ib qho system. Gases muaj siab dua entropy dua li cov kua, thiab cov kua muaj entropy siab dua cov khoom.
Koj paub li cas cov molecule twg muaj ntau entropy?
Qhov entropy ntawm ib yam khoom nce nrog nws qhov hnyav molecular thiab complexity thiab nrog kub. Lub entropy kuj nce ntxiv thaum lub siab los yog concentration ua me. Entropies ntawm cov pa roj ntau ntau dua li cov theem condensed.

Puas yog kev txhaum ntxeev dua siab dua?
Saib tawm ntawm lub vertex nrog lub kaum sab xis θ, sin(θ) yog qhov piv ntawm sab nraud mus rau hypotenuse, thaum cos(θ) yog qhov piv ntawm qhov nyob ib sab sab rau lub hypotenuse . Vim li cas sine sib npaug rau opposite tshaj hypotenuse?
Puas achiral molecules puas muaj enantiomers?
Tsuas yog ua kom pom tseeb, meso compound yog cov molecule uas muaj chiral chaw tab sis kuj muaj lub dav hlau sab hauv ntawm symmetry. Qhov no ua rau cov molecule achiral: nws tsis muaj enantiomer, thiab nws tsis tig dav hlau polarized teeb .
Puas achiral molecules puas muaj stereoisomers?
Achiral Diastereomer (Meso-Compounds) Ob ntawm cov stereoisomers no yog enantiomers thiab qhov thib peb yog achiral diastereomer, hu ua meso compound. Meso compounds yog achiral (optically inactive) diastereomers ntawm chiral stereoisomers. … Tus qauv ntawm meso-tartaric acid yuav raug tshuaj xyuas los ntawm Nyem Ntawm no.
Puas siab dua lossis qis dua bitrate zoo dua?
A tus nqi siab dua feem ntau txhais tau hais tias lub suab zoo dua"Bitrate yuav txiav txim siab lub suab ncaj ncees," hais tias tus tsim khoom thiab tus kws tshaj lij Gus Berry. "Koj tuaj yeem muaj lub suab kaw zoo tshaj plaws ntawm txhua lub sijhawm, tab sis yog tias koj ua si nrog tus nqi qis, nws yuav ua suab tsis zoo rau lwm qhov kawg.
Thaum lub sijhawm rov ua dua tshiab muaj kev rov yug dua tshiab ntawm kev txaus siab?
Renaissance txhais tau tias kev rov yug dua tshiab ntawm kev txaus siab hauv kos duab thiab kev kawm. Kev kos duab cuam tshuam los ntawm cov qauv thiab cov txheej txheem ntawm ancient Greece thiab Rome . Lub Renaissance yog kev rov yug dua tshiab ntawm dab tsi?
