Macluumaad dheeraad ah oo ku saabsan isla'egta O2 + 4Cr (OH)2 H 4H2O + 2Cr2O3

Waa maxay xaaladda falcelinta O2 (oxygen) ee ay la falgasho Cr (OH) 2 ()?

Heerkulka: heerkulka

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 Cr2O3 (chromium(iii) oxide)?

Cr (OH) 2 waxay la falgashaa oksijiin hawada ku jirta

Dhacdada O2 ka dib (oxygen) waxay la falgashaa Cr (OH) 2 ()

Falcelinta O2 (oxi) la falgal Cr (OH) 2 (Crom (II) Hidroksit) soo saaro H2O (nước) , xaalada heerkulka Nhiệt độ

Falcelinta soo saarta walaxda O2 (oxi) (oksijiin)

2KNO3 → 2KNO2 + O2 2Cu (MAYA3)2 → 2CuO + 4MAYA2 + O2 2CaOCl2 → o2 + 2CaCl2

Falcelinta soo saarta walaxda Cr (OH) 2 (Crom (II) Hidroxit) ()

2NaOH + CrCl2 → 2NaCl + Cr (OH)2 Ba (OH)2 + CrSO4 → Cr (OH)2 + BASO4 2NH4OH + CrCl2 → 2NH4Cl + Cr (OH)2

Falcelinta soo saarta walaxda H2O (nước) (biyo)

2H2S + 3O2 H 2H2O + 2SO2 Hcl + NaOH → H2O + NaCl H2SO4 + Na2SO3 → H2O + Na2SO4 + SO2

Falcelinta soo saarta walaxda Cr2O3 (Crom (III) oxit) (chromium (iii) oxide)

2NH3 + 2CrO3 H 3H2O + N2 + Cr2O3 2 (NH4)2Crown4 H 5H2O + N2 + 2NH3 + Cr2O3 O2 + 4Cr (OH)2 H 4H2O + 2Cr2O3
