鐵銹 是否等於 Fe2 O3?
發問:
Iron III oxide = Fe2 O3 ; Fe2 O3 = 赤鐵礦 ; 那麽 鐵銹 是否等於 Fe2 O3?
最佳解答:
Yes. During rusting, iron metals will lose electrons. Then iron ions(Fe 2+) then will react with oxygen in air to form iron oxide.(Fe2 O3) Then iron oxide will then hydrodated by water to form iron oxide* n water. (Fe2 O3*n*H2O) 2007-04-29 22:08:16 補充： 赤鐵礦is Fe2O3But since 赤鐵礦 is raw minerals ,there is many impurities.
正確泥講 唔係 Fe2O3 而係 Fe2O3．ｘH2O 因為鐵生銹要水... 所以唔係Fe2O3
