Macluumaad dheeraad ah oo ku saabsan isla'egta SiO2 + 4HF → 2H2O + SiF4

Waa maxay xaaladda falcelinta ee SiO2 (silikon dioxide) ee ay la falgasho HF (hydrogen fluoride)?

Wax macluumaad ah lagama helin isla'egtan kiimikada ah

Sharaxaad: Xaaladaha deegaanka ugu fiican ee falcelinta, sida heerkulka, cadaadiska, kicinta, iyo dareeraha. Catalysts waa walxo deddejiya xawaaraha (xawaaraha) falcelinta kiimikaad iyada oo aan la isticmaalin ama aan ka mid noqon badeecada dhamaadka. Kataliyayaashu wax saameyn ah kuma laha xaaladaha dheellitirka.

Sidee falcelintu u dhici kartaa una soo saari kartaa H2O (biyaha) iyo SiF4 ()?

Dhacdada ka dib SiO2 (silicon dioxide) waxay la falgashaa HF (hydrogen fluoride)

Isle'egtani ma hayso macluumaad gaar ah oo ku saabsan ifafaalaha.

Xaaladdan oo kale, waxaad u baahan tahay oo keliya inaad fiiriso si aad u aragto haddii walaxda sheyga SiF4, oo muuqda dhamaadka falcelinta.

Ama haddii mid ka mid ah walxaha fal-celinta soo socda HF (hydrogen fluoride), oo la waayo

Waa maxay macluumaadka kale ee muhiimka ah ee ay tahay inaad ka ogaato falcelinta

HF si fudud ayey u milmi kartaa silikoon dioxide. HF waxaa loo isticmaalaa in lagu xardho xarafka ama qaababka muraayadda. Sidaa darteed, waxaan u isticmaali karnaa inaan ku qurxinno muraayadda.

Macluumaad dheeraad ah oo ku saabsan maaddooyinka isle'egtu isticmaalaan

Falcelinta SiO2 (Silic dioxit) la falgal HF (Axit Hidrofloric) soo saaro H2O (nước)

Falcelinta soo saarta walaxda SiO2 (Silic dioxit) (silikoon dioxide)

2O2 + SiH4 H 2H2O + Haa2 H2Haa3 → H2O + Haa2 O2 + Si → SiO2

Falcelinta soo saarta walaxda HF (Axit Hidrofloric) (hydrogen fluoride)

2F2 + 2H2O → O2 + 4HF CAF2 + 2HCl → CaCl2 + 2HF F2 + H2 → 2HF

Falcelinta soo saarta walaxda H2O (nước) (biyo)

NaOH + C6H5Br → C6H5ONA + H2O + NaBr 2NaOH + NH4HSO4 H 2H2O + Na2SO4 + NH3 24HNO3 + FeCuS2 → Cu(MAYA3)2 + 10H2O + 2H2SO4 + 18MAYA2 + Fe (MAYA3)3

Falcelinta soo saarta walaxda SiF4 (Silic tetraflorua) ()

2F2 + Haa2 → o2 + SiF4 2F2 + Si → SiF4 Haa2 + 4HF → 2H2O + SiF4
