Answer 1

\(C_6H_{12}O_6 \xrightarrow{t^o,xt} 2CO_2 + 2C_2H_5OH\\ C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ CH_3COOH + C_2H_5OH \buildrel{{H_2SO_4,t^o}}\over\rightleftharpoons CH_3COOC_2H_5 + H_2O\\ CH_3COOC_2H_5 + H_2O \buildrel{{H_2SO_4}}\over\rightleftharpoons CH_3COOH + C_2H_5OH\\ 2CH_3COOH + Ca(OH)_2 \to (CH_3COO)_2Ca + 2H_2O\)

Answer 2

C6H12O6 => C2H5OH + 2CO2

C2H5OH+O2  CH3-COOH+H2O

CH3COOH+C2H5OH->CH3COOC2H5+H2O(môi trường H2SO4 đặc , nhiệt độ)

CH3COOC2H5+H2O->CH3COOH+C2H5OH(môi trường H2SO4 đặc , nhiệt độ)

2CH3COOH + Ca(OH)2 → (CH3COO)2Ca + 2H2O
