giúp mình vs a !!!!!!!!!!!

Em tham khảo nha:

\(\begin{array}{l}
a)\\
2C{H_3}COOH + Ca{(OH)_2} \to {(C{H_3}COO)_2}Ca + 2{H_2}O\\
2C{H_3}COOH + {K_2}O \to 2C{H_3}COOK + {H_2}O\\
2C{H_3}COOH + Zn \to {(C{H_3}COO)_2}Zn + {H_2}\\
2C{H_3}COOH + {K_2}C{O_3} \to 2C{H_3}COOK + C{O_2} + {H_2}O\\
2C{H_3}COOH + 2Na \to 2C{H_3}COONa + {H_2}\\
C{H_3}COOH + {C_2}{H_5}OH \leftrightarrows C{H_3}COO{C_2}{H_5} + {H_2}O\\
b)\\
2{C_2}{H_5}OH + 2Na \to 2{C_2}{H_5}ONa + {H_2}\\
C{H_3}COOH + {C_2}{H_5}OH \leftrightarrows C{H_3}COO{C_2}{H_5} + {H_2}O\\
c)\\
{C_2}{H_5}OH + {O_2} \xrightarrow{\text{ men giấm }} C{H_3}COOH + {H_2}O
\end{array}\)
