$2Fe(OH)_2+0,5O_2\xrightarrow{{t^o}} Fe_2O_3+2H_2O$
$4Al+3O_2\xrightarrow{{t^o}} 2Al_2O_3$
$Cu(OH)_2\xrightarrow{{t^o}} CuO+H_2O$
$MgCO_3\xrightarrow{{t^o}} MgO+CO_2$
$BaO+H_2O\to Ba(OH)_2$
$Al_2O_3+Ba(OH)_2\to Ba(AlO_2)_2+H_2O$
$Fe_2O_3+3CO\xrightarrow{{t^o}} 2Fe+3CO_2$
$CuO+CO\xrightarrow{{t^o}} Cu+CO_2$
$CO_2+Ba(OH)_2\to BaCO_3+H_2O$
$2CO_2+Ba(AlO_2)_2+4H_2O\to Ba(HCO_3)_2+2Al(OH)_3$
