Qhov ntxiv “ pawg ” muab los ntawm lub zog kinetic siab dua. Yog li pawg tsis nce nrog kub.
Kuj nug, molar loj nyob ntawm qhov kub thiab txias?
1 Teb. Zoo, molar loj yog qhov tsis tu ncua thiab ywj pheej ntawm kub thiab siab.
Qhov thib ob, cov dej loj puas hloov nrog qhov kub thiab txias? Thaum nce lossis txo kub , pawg ntawm dej yeej tsis kev hloov , yog ntim thiab yog li ceev uas kev hloov ntawm cua sov los yog txias lub dej . Tab sis dej exhibits exceptional khoom vim hais tias ntawm nce lub kub , ntim ntawm dej thawj txo mus txog rau ib qho tshwj xeeb kub 4 degree celsius.
Kuj Paub, puas muaj cov nyhuv tshav kub?
Pawg . Thaum koj kub qhov kub ntawm cov atoms hauv cov khoom txav nrawm dua. Yog li ntawd yog li cas tus pawg ntawm ib yam khoom hloov.
Lwm lub npe rau molar mass yog dab tsi?
Cov molar loj , tseem hu ua molecular hnyav, yog tus lej ntawm tag nrho pawg nyob rau hauv grams ntawm tag nrho cov atoms uas ua ib tug mole ntawm ib tug tshwj xeeb molecule. Chav tsev siv los ntsuas yog grams ib mole.

Puas yog stoichiometry raws li txoj cai ntawm kev txuag ntawm huab hwm coj?
Lub hauv paus ntsiab lus ntawm stoichiometry yog raws li txoj cai ntawm kev txuag ntawm huab hwm coj. Cov teeb meem tsis tuaj yeem tsim lossis rhuav tshem, yog li qhov loj ntawm txhua lub ntsiab lus tam sim no hauv cov khoom lag luam ntawm cov tshuaj tiv thaiv tshuaj yuav tsum sib npaug rau qhov loj ntawm txhua thiab txhua lub ntsiab lus tam sim no hauv cov reactant
Qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov sib faib coefficient yog dab tsi?
Ib qho inverse linear kev sib raug zoo tau pom ntawm qhov kub thiab txias thiab qhov sib faib coefficient. CEEB TOOM: Nyob rau hauv ib qho kev ntsuas kub, qhov sib faib coefficients isoflurane thiab sevoflurane txo qis thaum qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane
Dab tsi yog qhov feem pua ntawm magnesium los ntawm huab hwm coj hauv magnesium oxide?
Cov feem pua ntawm cov ntsiab lus Element Symbol Mass Percent Magnesium Mg 60.304% Oxygen O 39.696%
Qhov twg yog tus naj npawb atomic thiab huab hwm coj ntawm lub rooj zaum?
Nyob rau sab laug yog tus lej atomic, lossis tus naj npawb ntawm protons. Hauv nruab nrab yog tsab ntawv cim rau lub caij (piv txwv li, H). Hauv qab no yog cov txheeb ze atomic loj, raws li xam rau cov isotopes pom nyob rau hauv lub ntiaj teb
Dab tsi yog qhov kev sib raug zoo ntawm huab hwm coj thiab ntim?
Qhov loj npaum li cas yog qhov hnyav npaum li cas, qhov ntim qhia koj tias nws loj npaum li cas, thiab qhov ntom ntom yog loj faib los ntawm ntim
