Answer 2

The reaction you have mentioned is the dehydration of ethanol (C2H5OH) to form ethylene (CH2=CH-CH=CH2). In this reaction, ethanol loses a water molecule to produce ethylene gas.

The balanced chemical equation for this reaction is:

C2H5OH -> CH2=CH-CH=CH2 + H2O

In the reaction, one molecule of ethanol decomposes to form one molecule of ethylene and one molecule of water. Ethanol loses one water molecule, and the remaining carbon and hydrogen atoms rearrange to form the ethylene molecule.

It's important to note that this reaction typically requires specific conditions, such as the presence of a catalyst like sulfuric acid or heat, to facilitate the dehydration process. Without the appropriate conditions, ethanol will not spontaneously convert to ethylene.
