How many carbon dioxide and water molecules will be there on the product side, if the following equation is made balanced
C2H5OH+O2→CO2+H2O
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 2 and 3, respectively.
The balanced chemical equation for the combustion of ethanol (C2H5OH) is:
C2H5OH + 3O2 → 2CO2 + 3H2O
Therefore, on the product side of the balanced equation, there will be 2 carbon dioxide (CO2) molecules and 3 water (H2O) molecules. This shows the stoichiometric balance of carbon, hydrogen, and oxygen atoms on both sides of the equation, ensuring the law of conservation of mass is followed.
