Hoàn thành pthh: 1) CaCO3-> CaO (2) CaO->CaC2 (3)CaC2->C2H2 (4)C2H2->C2H4 (5) C2H4->C2H5OH (6)C2H5OH->CH3COOH (7) CH3COOH -> CH3COONa

Em tham khảo nha:

\(\begin{array}{l}
(1)\,CaC{O_3} \xrightarrow{t^0} CaO + C{O_2}\\
(2)\,CaO + 3C \to Ca{C_2} + CO\\
(3)\,Ca{C_2} + 2{H_2}O \to Ca{(OH)_2} + {C_2}{H_2}\\
(4)\,{C_2}{H_2} + {H_2} \xrightarrow{t^0,Pd/PdCO_3} {C_2}{H_4}\\
(5){C_2}{H_4} + {H_2}O \xrightarrow{t^0,H_2SO_4} {C_2}{H_5}OH\\
(6)\,{C_2}{H_5}OH + {O_2} \xrightarrow{\text{ men giấm }} C{H_3}COOH + {H_2}O\\
(7)\,2C{H_3}COOH + 2Na \to 2C{H_3}COONa + {H_2}
