Answer

  1. $ \text{C}_2{\text{H}}_5\text{OH}+\text{3O}_2\rightarrow\text{2CO}_2+\text{3H}_2{\text{O}}$
  2. $\text{C}_2\text{H}_5\text{OH}\xrightarrow[443\text{K}]{\text{ }\text{ }\text{Conc.}\text{H}_2\text{SO}_4\text{ }\text{ }\text{ }\text{ }}{\text{C}}_2{\text{H}}_4+\text{H}_2\text{O}$
  3. $\text{CH}_3\text{COOH}+\text{NaH}\text{CO}_3\rightarrow\text{CH}_3\text{COONa}+\text{H}_2\text{O}+\text{CO}_2$
