Carry out the transformations: glucose-ethanol-potassium ethanoate.

Let’s compose the reaction equations for organic compounds:
С6Н12О5 = 2С2Н5ОН + 2СО2 – fermentation of glucose occurs with the participation of yeast, ethanol is released;
2СН3 – СН2 – ОН + 2K = 2CH3 – CH2 – OK + H2 – substitution, goes with the participation of ethanol and potassium metal, potassium ethylate is obtained.
The given reactions show the connection between carbohydrates and alcohols. The organic salt of potassium ethylate (potassium alcoholate) is used as an adsorbent.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
