Em tham khảo nha:
\(\begin{array}{l}
a)\\
2C{H_3}COOH + CaC{O_3} \to {(C{H_3}COO)_2}Ca + C{O_2} + {H_2}O\\
b)\\
{C_2}{H_4} + B{r_2} \to {C_2}{H_4}B{r_2}\\
c)\\
{C_6}{H_6} + B{r_2} \xrightarrow{t^0,Fe} {C_6}{H_5}Br + HBr\\
d)\\
C{H_3}COO{C_2}{H_5} + NaOH \xrightarrow{t^0} C{H_3}COONa + {C_2}{H_5}OH\\
e)\\
C{H_4} + 2{O_2} \xrightarrow{t^0} 2C{O_2} + 2{H_2}O
\end{array}\)
