Which is the balanced equation for the complete combustion of ethanol (C2H5OH) in oxygen gas?
A) C2H5OH + 7 O2 → 2 CO2 + 3 H2O
B) 2 C2H5OH + 7 O2 → 4 CO2 + 6 H2O
C) 2 C2H5OH + 7/2 O2 → 4 CO2 + 6 H2O
D) C2H5OH + 7 O2 → 4 CO2 + 6 H2O

Final Answer :
B
Explanation :
The balanced chemical equation for the complete combustion of ethanol (C2H5OH) is 2C2H5OH+7O2→4CO2+6H2O2 C_2H_5OH + 7 O_2 \rightarrow 4 CO_2 + 6 H_2O2C2H5OH+7O2→4CO2+6H2O , which matches choice B. This equation ensures that the number of each type of atom on the reactant side equals the number on the product side, fulfilling the law of conservation of mass.
