Ntawm cua sov, ferrous sulphate crystals poob dej thiab anhydrous ferrous sulphate (FeSO4) yog tsim . Yog li lawv cov xim hloov ntawm lub teeb ntsuab mus rau dawb. Ntawm cov cua kub ntxiv, anhydrous ferrous sulphate decomposes tsim ferric oxide (Fe2O3), sulfur dioxide (SO 2) thiab sulfur trioxide (SO3).
Kev soj ntsuam dab tsi thaum ferrous sulphate rhuab?
Ntawm cua sov ferrous sulphate cov crystals poob dej thiab tig lub teeb ntsuab. Ntawm cov cua sov ntxiv Nws decomposes rau ferric oxide (Fe2O3), sulfur dioxide (SO2) thiab sulfur trioxide (SO3).
Thaum ferrous sulphate yog rhuab heev nws tau hloov xim los ntawm?
Kev piav qhia: Thaum ferrous sulfate yog rhuab heev nws undergoes decomposition los tsim ferric oxide raws li ib yam khoom tseem ceeb nrog los ntawm kev hloov xim ntawm ntsuab rau daj.
Thaum ntsuab Xim ferrous sulphate yog cua sov?
Kev piav qhia: Thaum ntsuab xim ferrous sulphate crystals tau rhuab, lub xim ntawm cov siv lead ua hloov vim nws poob dej ntawm crystallisation.
Thaum ferrous sulphate rhuab ces nws tsim tsw ntxhiab ntawm sulfur vim li cas?
Yog li, cov tshuaj tiv thaiv yog decomposition reaction. Yog li, los ntawm cov tshuaj tiv thaiv peb tuaj yeem paub tias peb cov lus teb raug yog kev xaiv D. Vim tias, hauv kev xaiv D, muaj cov decomposition ntawm ferrous sulphate. Thiab nyob rau hauv qhov kev xaiv no, leej fajDioxide thiab trioxide yog tsim los ntawm decomposition ntawm ferrous sulphate.
Pom zoo:
Thaum anisole rhuab nrog nyob zoo cov khoom puas yog?
Thaum alkyl aryl ether yog rhuab nrog HI, lub halogen mus nrog alkyl pawg. Yog li ntawd, ntawm cua sov anisole (methyl phenyl ether) nrog HI, phenol thiab methyl iodidetau. Dab tsi yog cov khoom tsim thaum anisole kho nrog HI? Phenyl iodide thiab methyl iodide.
Thaum tooj liab sulfate pentahydrate rhuab?
- Thaum tooj liab sulphate pentahydrate yog rhuab, nws poob dej ntawm crystallization dej ntawm crystallization Classically, "dej ntawm crystallization" yog hais txog cov dej uas pom nyob rau hauv lub crystalline moj khaum ntawm ib tug hlau complex los yog ib tug ntsev.
Vim li cas thermosetting polymers tsis yaj thaum rhuab?
Thermoset polymers tsis soften thaum rhuab vim cov molecules yog cross-linked ua ke thiab nyob twj ywm nruj. Cov tshuaj sib txuas ua ke tsim nyob rau hauv ib lub polymer, thiab cov duab ntawm cov khoom polymer, cuam tshuam rau nws cov khoom.
Thaum tooj liab rhuab nrog concentrated hno3 nws tsim?
Hint: Thaum tooj liab reacts nrog nitric acid, cupric nitrate yog tsim nrog cov pa lom liab liab xim av nrogcov ntxhiab tsw ntxhiab tsw. Thaum tooj liab yog rhuab nrog concentrated nitric acid nws tsim? Cov tshuaj tiv thaiv ua rau cov roj ntsha liab-xim av nitrogen dioxide thiab cov kua kub, cov ntsiab lus ntawm tooj liab (II) nitrate, uas yog xiav.
Thaum twg ammonium nitrate rhuab?
Thaum ammonium nitrate tau rhuab, nws decomposes exothermically rau nitrous oxide thiab dej. dissociates endothermically rau ammonia thiab nitric acidvapor. Thaum ammonium nitrate tau rhuab heev? Ammonium Nitrate (NH4NO3) thaum rhuab muab Nitrous Oxide (N2O) kuj hu ua luag roj thiab Dej (H2O).
