Complete the following chemical equations:

(i) \[{{C}_{2}}{{H}_{5}}OH+{{O}_{2}}\to \]

(ii) \[{{C}_{2}}{{H}_{5}}OH+{{O}_{2}}\xrightarrow[443K]{Conc.{{H}_{2}}S{{O}_{4}}}\]

(iii) \[C{{H}_{3}}COOH\mathrm{  }+\mathrm{  }NaHC{{O}_{3}}\to \]

Answer:

(i) \[{{C}_{2}}{{H}_{5}}OH+7/2\mathrm{ }{{O}_{2}}\to 2C{{O}_{2}}+3{{H}_{2}}O+\text{Energy}\]

(ii) \[{{C}_{2}}{{H}_{5}}OH\xrightarrow[443K]{Conc.\mathrm{ }{{H}_{2}}S{{O}_{4}}}C{{H}_{2}}=C{{H}_{2}}+{{H}_{2}}O\]

(iii) \[C{{H}_{3}}COOH+NaHC{{O}_{3}}\to C{{H}_{3}}COONa+{{H}_{2}}O+C{{O}_{2}}\]
