Rau tshuav nyiaj li cas CuO + H2SO4 = CuSO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab. tshuaj sib npaug . 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 tebchaw) rau tshuav nyiaj li cas tus kev sib npaug rau tooj liab (II) oxide + Sulfuric acid.
Hais txog qhov no, dab tsi yog cov tshuaj tiv thaiv ntawm tooj liab oxide thiab sulfuric acid?
Tooj (II) oxide , ib qho khoom dub, thiab tsis muaj xim dilute sulfuric acid teb tsim tawm tooj liab (II) sulfate, muab cov yam ntxwv xiav xim rau cov tshuaj. Los ntawm cov tshuaj no, xiav tooj liab (II) sulfate pentahydrate crystals tuaj yeem tau txais.
Tsis tas li ntawd, qhov sib npaug ntawm tooj liab thiab hydrochloric acid yog dab tsi? Balanced equation: CU + 2 HCl = CUCl2 + H2
| Reaction stoichiometry txwv reagent | ||
|---|---|---|
| Compound | # | Molar Mass |
| HCl | 2 | 36.46094 |
| CUCl2 | 1 | 320.94561 |
| H2 | 1 | 2.01588 |
Thiab cov lus nug yog, puas tooj liab puas nrog sulfuric acid?
tooj liab ua tsis yog teb nrog dilute sulfuric acid raws li nws cov peev xwm txo tau siab dua li ntawm hydrogen. tooj liab ua tsis hloov hydrogen los ntawm tsis-oxidizing kua qaub zoo li HCl los yog dilute H2SO4 . Yog li, thaum tooj liab yog rhuab nrog conc. H2SO4 , ib redox tshuaj tiv thaiv tshwm sim thiab cov kua qaub tau txo kom sulfur dioxide.
Vim li cas koj kub sulfuric acid ua ntej ntxiv tooj liab oxide?
Nws yog los pab cov tshuaj tiv thaiv los ntawm kev muab lub zog rau cov tshuaj tiv thaiv kom muaj kev tawg ntawm cov ntawv cog lus nyob rau hauv Tooj oxide enabling tsim ntawm ionic tebchaw nrog cov kua qaub ions.

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
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
Puas yog tooj liab oxide soluble hauv sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
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
