Cov tshuaj tiv thaiv ua ob dej molecules, yog li ntawd mole ratio nruab nrab oxygen thiab dej yog 1:2, mole ratio nruab nrab dej thiab hydrogen yog 2: 2.
Tsis tas li ntawd, qhov mole piv ntawm co2 rau h2o yog dab tsi?
Cov tshuaj formula qhia peb tus mole ratio . CO2 = 1 CO2 molecule: 1 C atom: 2 O atoms. 1 C12H22O11 molecule: 12 O2 molecules: 12 CO2 molecules: 11 H2O molecules.
Ib tug kuj yuav nug, ua li cas koj xam tus mole ratio? Hloov cov huab hwm coj ntawm txhua lub hauv paus rau moles siv cov molar loj los ntawm lub sij hawm lub sij hawm. Faib txhua mole tus nqi los ntawm tus lej tsawg tshaj plaws ntawm moles xam . Hloov mus rau tus lej uas nyob ze tshaj plaws. Qhov no yog qhov mole ratio ntawm cov ntsiab lus thiab yog sawv cev los ntawm subscripts nyob rau hauv lub empirical formula.
Dhau li ntawm no, qhov piv ntawm h20 yog dab tsi?
1:8
Qhov piv ntawm mole ntawm oxygen rau propane yog dab tsi?
Rau tshuaj propane Peb muaj 3 carbons thiab 8 hydrogen atoms, yog li cov gram-molecular hnyav (312 + 81) = 44g / mol. Cov mole ratio ntawm oxygen rau carbon dioxide yog 5: 3, yog li rau txhua tsib moles ntawm oxygen reacted, peb moles carbon dioxide yog tsim. 1.12 Moles oxygen ⋅4mol Dej 5mol oxygen = 0.89 moles ntawm dej.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov tseeb ntawm thaj chaw saum npoo rau qhov sib piv ntawm cov kab mob nyob?
Raws li qhov loj ntawm lub cev nce, nws thaj chaw saum npoo mus rau qhov sib piv qis. Qhov no txhais tau hais tias nws muaj qhov tsawg dua qhov chaw muaj rau cov khoom sib txawv, yog li tus nqi ntawm diffusion yuav tsis nrawm txaus kom tau raws li nws cov kev xav tau ntawm cov hlwb
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
