How is the complete combustion of ethanol (C2H5OH) in oxygen gas represented?

A) 2 C2H5OH + 2 O2 → 4 CO2 + 6 H2O
B) 2 C2H5OH + 7 O2 → 4 CO2 + 6 H2O
C) C2H5OH + 7 O2 → 4 CO2 + 6 H2O
D) C2H5OH + 4 O2 → 4 CO2 + 6 H2O

Ethanol

A volatile, flammable, colorless liquid, commonly known as alcohol, used in beverages and as a solvent or fuel.

Final Answer :
B
Explanation :
The complete combustion of ethanol (C2H5OH) in oxygen (O2) produces carbon dioxide (CO2) and water (H2O). The balanced chemical equation for this reaction is: 2 C2H5OH + 7 O2 → 4 CO2 + 6 H2O. This corresponds to choice B.
