Video: Koj ua li cas sib npaug sodium thiab oxygen?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
Rau balance Na + O2 = Na2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm chemicalequation. Thaum koj paub ntau npaum li cas ntawm txhua hom atom koj tuaj yeem hloov pauv cov coefficients (tus lej nyob rau pem hauv ntej ntawm atoms lossis cov khoom sib txuas) rau tshuav nyiaj li cas qhov sib npaug.
Hais txog qhov no, qhov sib npaug ntawm sodium thiab oxygen yog dab tsi?
Sodium reacts nrog oxygen ua form sodium oxide thiab muaj cov hauv qab no balanced chemicalequation : 4 Na + O2 2 Na2o.
Tsis tas li ntawd, sodium thiab oxygen yog dab tsi? Keeb Kwm Teb: Dab tsi yog cov tshuaj tiv thaiv kab mob sib kis sodium thiab oxygen ? Txij li thaum, sodium yog ib tug heev reactive hlau, nws nyhav rau react nrog oxygen ua form sodium oxide tab sis qhov no yog ib qho tsis ruaj khov thiab sai sai nrog hydrogen tsim sodium hydroxide.
Ib yam li ntawd, yuav ua li cas thaum sodium reacts nrog oxygen?
Kev tshwm sim nrog huab cua, dej, thiab hydrogen Lub corrosion ntawm cov khoom sodium los ntawm oxygen kuj yog accelerated los ntawm lub xub ntiag ntawm me me ntawm impurities nyob rau hauv lub sodium . Hauv huab cua zoo tib yam, sodium hlau reacts tsim a sodium hydroxide zaj duab xis, uas tuaj yeem nqus cov pa roj carbon dioxide los ntawm huab cua, tsim sodium bicarbonate.
Peb yuav sib npaug li cas?
Txoj Kev 1 Ua ib qho piv txwv
- Sau koj qhov kev sib npaug.
- Sau tus naj npawb ntawm atoms rau ib lub caij.
- Txuag hydrogen thiab oxygen rau qhov kawg, vim lawv feem ntau nyob ntawm ob sab.
- Pib nrog ib lub ntsiab lus.
- Siv cov coefficient kom sib npaug ntawm ib qho carbon atom.
- Ntsuas cov hydrogen atoms tom ntej.
- Ntsuas cov pa oxygen atoms.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Koj tuaj yeem qhia tau li cas yog tias ob qhov sib npaug sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv qhov sib npaug seb puas yog ob kab sib npaug los ntawm kev sib piv lawv cov nqes hav. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel. Yog tias txoj kab nqes sib txawv, cov kab tsis sib npaug. Tsis zoo li cov kab sib luag, cov kab perpendicular sib tshuam
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
