Tshuaj cov tshuaj tiv thaiv nrog barium nitrate :
Ba(NO3)2 = Ba(NO2)2 + O2 (594-620°C), 2Ba(NO3)2 = 2BaO + 4NO2 + O2 (620-670°C). Ba(NO3)2 + 4H(0)(Zn, diluted HCl) = Ba(NO2)2 + 2H2O. Ba(NO3)2 + H2SO4(diluted) = BaSO4↓ + 2HNO3.
Yog li ntawd, dab tsi dissolves barium nitrate?
Thawj koom nrog dissolving barium carbonate nyob rau hauv nitric acid, tso cai rau cov hlau impurities rau precipitate, ces lim, evaporated, thiab crystallized. Qhov thib ob xav tau kev sib txuas barium sulfide nrog nitric acid. Nws tshwm sim ib txwm li cov ntxhia tsis tshua muaj nitrobarite.
Ib sab saum toj no, puas yuav barium nitrate precipitate hauv dej? Koj ua tau pom tias barium sulfate yog teev raws li "s", uas txhais tau hais tias nws ua tsis yaj hauv dej , yog li ntawd nag xob nag cua tawm ntawm kev daws, sib sau ua ke. raws li BaSO4 ↓, uas qhia tias nws yog a nag xob nag cua.
Ua li no, koj sau barium nitrate li cas?
Teb thiab piav qhia: Tus qauv raug rau barium nitrate yog Ba(NO3)2. Cov qauv tshuaj no qhia peb tias ib qho atom ntawm barium yuav khi nrog ob nitrate molecules.
Puas yog barium nitrate yog acid?
Barium nitrate yog ib qho dej soluble crystalline heev Barium qhov chaw siv tau tshaj nitrates thiab qis dua ( acidic ) pH. Txhua yam xim hlau nitrates yog inorganic ntsev ntawm ib tug muab hlau cation thiab cov nitrate anion.

Lub kaum sab xis ntawm qhov cuam tshuam cuam tshuam li cas rau cov tsos ntawm cov ntshav?
Thaum cov ntshav raug cuam tshuam, cov tee dej tau tawg los ntawm huab cua. Thaum cov tee dej no tawm tsam ib qho chaw, cov duab ntawm cov stain hloov nyob ntawm lub kaum sab xis ntawm qhov cuam tshuam, kev tshaj tawm, kev ncua deb thiab hom ntog cuam tshuam. Raws li lub kaum sab xis ntawm qhov cuam tshuam hloov, yog li qhov tshwm sim ntawm qhov tshwm sim stain
Dab tsi yog qhov sib txawv ntawm cov rog yuav cuam tshuam rau kev sib cuam tshuam ntawm cov dej molecules?
1 Teb. Qhov tseeb, dej muaj tag nrho peb hom kev sib xyaw ua ke, nrog qhov muaj zog tshaj plaws yog hydrogen bonding. Txhua yam muaj London dispersion yuam cov kev sib cuam tshuam tsis muaj zog yog ib ntus dipoles uas tsim los ntawm kev hloov ntawm electrons nyob rau hauv ib lub molecule
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Puas yog cov kev cuam tshuam cuam tshuam ib txwm endothermic?
Cov txheej txheem ntawm dissolving yog endothermic thaum tsawg zog tawm thaum dej molecules "daim ntawv cog lus" rau cov kuab tshuaj dua yog siv los rub cov kua sib nrug. Vim tias lub zog tsawg dua yog tso tawm ntau dua li siv, cov molecules ntawm cov tshuaj txav qeeb dua, ua rau qhov kub thiab txias
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?
Kev ua liaj ua teb tuaj yeem cuam tshuam tsis zoo rau peb ib puag ncig, suav nrog kev poob ntawm biodiversity, dej paug, kev hloov pauv huab cua, av yaig thiab muaj kuab paug
