Question

Ethanol burns in air, balance the equation...

Options:
A. C2H5OH + 3O2 → 2CO2 + 3H2O
B. C2H5OH + 2O2 → CO2 + 3H2O
C. C2H5OH + 4O2 → 2CO2 + 4H2O
D. C2H5OH + O2 → CO2 + H2O

Answer 1

The correct balanced equation for the combustion of ethanol in air is Option A: C2H5OH + 3O2 --> 2CO2 + 3H2O.

Step-by-step explanation:

Option A is the correct balanced equation for the combustion of ethanol in air:

C2H5OH + 3O2 → 2CO2 + 3H2O

In this reaction, ethanol (C2H5OH) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). The balanced equation ensures that there is an equal number of atoms on both sides of the reaction.
