Dãy 1:
$(C_6H_{10}O_5)_n+nH_2O\xrightarrow{axit} nC_6H_{12}O_6$
$C_6H_{12}O_6\xrightarrow[30-32^oC]{men\ rượu} 2C_2H_5OH+2CO_2$
$C_2H_5OH+CH_3COOH\mathop{\huge{\rightleftharpoons}}\limits^{\small{H_2SO_4đ,t^o}} CH_3COOC_2H_5+H_2O$
$CH_3COOC_2H_5+NaOH\to CH_3COONa+C_2H_5OH$
Dãy 2:
$2Fe+3Cl_2\xrightarrow{t^o} 2FeCl_3$
$FeCl_3+3AgNO_3\to Fe(NO_3)_3+3AgCl$
$Fe(NO_3)_3+3NaOH\to Fe(OH)_3+3NaNO_3$
$2Fe(OH)_3\xrightarrow{t^o} Fe_2O_3+3H_2O$
$Fe_2O_3+3H_2\xrightarrow{t^o} 2Fe+3H_2O$
