Ib feem pua ntawm cov khoom
| Element | Cim | Pawg Feem Xyuam |
|---|---|---|
| Aluminium | Al | 23.062% |
| Cov pa roj carbon | C | 15.399% |
| Oxygen | O | 61.539% |
Yog li ntawd, pes tsawg feem pua ntawm carbon nyob rau hauv aluminium carbonate yog dab tsi?
Cov ntsiab lus ntawm Al2 (CO3) 3
| Element | Cim | Feem pua Mass |
|---|---|---|
| Aluminium | Al | 23.0622 |
| Cov pa roj carbon | C | 15.3990 |
| Oxygen | O | 61.5388 |
Tom qab ntawd, lo lus nug yog, puas yog al2 co3 3 ib qho khoom? Corundum yog ntuj Al2O3. Emery yog ib qho tsis huv crystalline ntau yam ntawm Al2O3.]; Dawb, tsw, crystalline hmoov.
Nrhiav los ntawm reactants (Al 2(CO 3 ) 3 )
| 1 2 | |
|---|---|
| 1 | Al2(CO3)3 → CO2 + Al2O3 |
| 2 | HNO3 + Al2(CO3)3 → H2O + CO2 + Al(NO3)3 |
| 3 | H2O4 + Al2(CO3)3 → H2O + CO2 + Al2(SO4)3 |
Qhov thib ob, qhov molecular loj ntawm al2 co3 3 yog dab tsi?
Aluminium carbonate
