Tom qab ntawd, multiply tus lej ntawm qhov tshwm sim ua bythe tus lej ntawm rolls. Txij li thaum peb tsuas yog dov ib zaug, lub tus naj npawb ntawm qhov tshwm sim tau yog 6. Cov lus teb yog qhov qauv qhov chaw yog 1, 2, 3, 4, 5, 6 thiab lwm yam tus lej ntawm qhov tshwm sim tau yog 6.
Tsis tas li ntawd, koj yuav pom qhov tshwm sim ntawm qhov chaw piv txwv li cas?
Nws yog qhov piv ntawm qhov loj ntawm qhov kev tshwm sim qhov chaw tothe loj qauv qhov chaw . Ua ntej, koj yuav tsum tau txiav txim qhov loj ntawm cov qauv qhov chaw . Qhov loj ntawm cov qauv qhov chaw yog tag nrho cov txiaj ntsig tau. For piv txwv , thaum koj dov 1 tuag, tus qauv qhov chaw yog 1, 2, 3, 4, 5, 6.
Qhov thib ob, koj yuav nrhiav tau cov txiaj ntsig tau li cas? Cov khoom ntawm cov no qhov tshwm sim yuav muab tag nrho rau koj qhov tshwm sim rau txhua qhov xwm txheej. Koj tuaj yeem siv Txoj Cai suav suav kom pom qhov tshwm sim ntawm cov xwm txheej. Qhov tshwm sim ntawm ib qho kev tshwm sim yog sib npaug rau qhov piv ntawm qhov zoo qhov tshwm sim mus rau tag nrho cov naj npawb ntawm sib npaug tej zaum yuav ua tau.
Hais txog qhov no, lub hauv paus ntsiab lus twg pab peb txiav txim siab tag nrho cov txiaj ntsig hauv ib qho piv txwv?
Kev suav qhov tseem ceeb Txoj Cai 6 los yog 36 zoo sib xws qhov tshwm sim . Flipping threecoins: Txhua npib muaj 2 qhov sib npaug qhov tshwm sim , yog li ntawd qauv qhov chaw yog 2.
Qhov chaw piv txwv ntawm kev sim yog dab tsi?
Nyob rau hauv probability theory, lub qauv qhov chaw (tseem hu ua qauv piav qhia qhov chaw los yog muaj peev xwm space) ntawm kev sim los yog kev sim random yog cov txheej txheem ntawm txhua qhov tshwm sim lossis cov txiaj ntsig ntawm qhov ntawd kev sim.

Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas koj nrhiav tau tus naj npawb ntawm molecules nyob rau hauv ib tug tshuaj formula?
Multiply Moles los ntawm Avogadro Constant Muab cov naj npawb ntawm moles los ntawm Avogadro tas li, 6.022 x 10^23, los xam cov lej ntawm cov molecules hauv koj cov qauv
Yuav ua li cas koj xam tus naj npawb ntawm qhov tshwm sim?
Lub hauv paus ntsiab lus suav yog txoj cai tseem ceeb rau kev suav cov lej ntawm qhov tshwm sim tau. Yog hais tias muaj p possibilities rau ib qho kev tshwm sim thiab q possibilities rau ib qhov kev tshwm sim thib ob, ces tus naj npawb ntawm possibilities rau ob qhov xwm txheej yog p x q
Yuav ua li cas koj nrhiav tau tus naj npawb ntawm electrons nyob rau hauv ib tug uncharged atom?
Tus naj npawb atomic sawv cev rau tus naj npawb ntawm protons hauv atom lub nucleus. Hauv ib qho atom uas tsis tau them nyiaj, tus naj npawb ntawm cov protons ib txwm sib npaug ntawm cov electrons. Piv txwv li, carbon atoms suav nrog rau protons thiab rau electrons, yog li cov pa roj carbon monoxide yog 6
Yuav ua li cas koj nrhiav tau tus naj npawb ntawm covalent bonds nyob rau hauv ib tug compound?
Tus naj npawb ntawm daim ntawv cog lus rau ib qho atom nruab nrab yog sib npaug rau cov xov tooj ntawm cov hluav taws xob hauv lub plhaub valence tag nrho (2 los yog 8 electrons) rho tawm cov valence electrons. Txoj kev no ua haujlwm vim tias txhua daim ntawv cog lus sib cog lus uas ib qho atom tsim ntxiv lwm lub tshuab hluav taws xob rau lub atoms valence plhaub yam tsis hloov nws cov nqi
