Rau balance HBr + Ba(OH)2 = BaBr2 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug.
Ntawm no, koj yuav ua li cas neutralize hydrobromic acid?
1 Teb
- Lub hydrobromic acid neutralizes calcium carbonate nyob rau hauv ib tug ob peb hloov cov tshuaj tiv thaiv. Cov khoom yog calcium bromide thiab carbonic acid.
- Cov carbonic acid tsis ruaj khov. Nws decomposes tsim carbon dioxide thiab dej.
- Cov tshuaj tiv thaiv yog qhov sib npaug ntawm ob qhov sib npaug saum toj no. 2HBr + CaCO3 → CaBr2 + H2O + CO2
Tsis tas li ntawd, qhov sib npaug tshuaj sib npaug rau cov tshuaj tiv thaiv acid ntawm hydrobromic acid nrog sodium hydroxide yog dab tsi? A) NaOH (aq) + HBr(aq) → H2O(l) + NaBr(aq) B)
Tsis tas li ntawd, hydrobromic acid siv rau dab tsi?
Hydrobromic acid yog mas siv rau Kev tsim cov inorganic bromides, tshwj xeeb tshaj yog cov bromides ntawm zinc, calcium, thiab sodium. Nws yog ib qho tseem ceeb reagent rau tsim organobromine tebchaw. Qee cov ethers yog cleaved nrog HBr. Nws kuj catalyzes alkylation cov tshuaj tiv thaiv thiab tshem tawm ntawm qee yam ores.
Dab tsi yog cov tshuaj formula rau hydrobromic acid suav nrog theem?
Hydrobromic acid yog qhov kev daws teeb meem ntawm hydrogen bromide ( HBr ) nyob rau hauv dej, thiab muaj zog ntxhia kua qaub . Formula thiab qauv : Cov chemical formula ntawm hydrobromic acid (aqueous hydrogen bromide ) yog HBr , thiab nws cov molar loj yog 80.9 g / mol.

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
