Question

cho các oxit sau Al2O3 ,FeO,Fe2O3,Fe3O4,PbO,ZnO,MgO.viết pthh(nếu có )khi các oxit trên pư vs 

a.H2

b,CO

c.C

Answer 1

$a\bigg)$

$FeO+H_2\xrightarrow{t^o}Fe+H_2O$

$Fe_2O_3+3H_2\xrightarrow{t^o}2Fe+3H_2O$

$Fe_3O_4+4H_2\xrightarrow{t^o}3Fe+4H_2O$

$PbO+H_2\xrightarrow{t^o}Pb+H_2O$

$ZnO+H_2\xrightarrow{t^o}Zn+H_2O$

$b\bigg)$

$FeO+CO\xrightarrow{t^o}Fe+CO_2$

$Fe_2O_3+3CO\xrightarrow{t^o}2Fe+3CO_2$

$Fe_3O_4+4CO\xrightarrow{t^o}3Fe+4CO_2$

$PbO+CO\xrightarrow{t^o}Pb+CO_2$

$ZnO+CO\xrightarrow{t^o}Zn+CO_2$

$c\bigg)$

$2FeO+C\xrightarrow{t^o}2Fe+CO_2$

$2Fe_2O_3+3C\xrightarrow{t^o}4Fe+3CO_2$

$Fe_3O_4+2C\xrightarrow{t^o}3Fe+2CO_2$

$2PbO+C\xrightarrow{t^o}2Pb+CO_2$

$2ZnO+C\xrightarrow{t^o}2Zn+CO_2$
