Decomposition thiab disassociation xa mus rau cov txheej txheem zoo sib xws, tab sis lawv txawv. Qhov sib txawv tseem ceeb ntawm lawv yog tias cov tshuaj tiv thaiv decomposition feem ntau tsis tuaj yeem thim rov qab thaum cov kev cuam tshuam tsis sib xws reversible thiab muaj nyob hauv qhov sib npaug.
Puas yog cov tshuaj tiv thaiv decomposition thim rov qab lossis tsis rov qab?
Kev daws: Thermal decomposition & thermal dissociation Thermal decomposition yog rhuav tshem ib qho chaw ua ob lossis ntau lub ntsiab lus, lossis rau hauv ob lub tebchaw tshiab nrog kev pab ntawm tshav kub. Cov tshuaj tiv thaiv no yog irreversible Thermal dissociation is breaking a substance into two or simpler substances with help of heating.
Dab tsi yog reversible decomposition tshuaj hu ua?
Kev piav qhia: Ib qho kev hloov pauv hloov pauv hloov pauv tau tshwm sim tsuas yog los ntawm cua sov yog thermal dissociation.
Yuav ua li cas yog 4 yam piv txwv ntawm kev rov qab los?
- Ib qho tshuaj tiv thaiv rov qab. Bunsen burner heats ib lub tais ntawm hydrated tooj liab (II) sulfate.
- Dej tau tawm mus, tawm hauv cov dej tsis muaj tooj liab (II) sulfate.
- Lub tshuab hluav taws xob tau muab tua thiab dej ntxiv siv lub pipette.
- Lub tais tam sim no muaj hydrated tooj liab (II) sulfate dua.
Koj tuaj yeem qhia tau li cas yog tias qhov kev tawm tsam thim rov qab?
Q: Hauv kev sib npaug tshuaj, cov tshuaj tiv thaiv rov qab tau sawv cev nrog ob tus xub, ib qho taw qhia rau txhua qhov kev taw qhia. Qhov no qhia tau tias qhov kev tawm tsam tuaj yeem mus rau ob txoj hauv kev.
