Question

During this reaction, how many molecules of ethanol (C2H6O) are produced?

A) 5 molecules of ethanol
B) 10 molecules of ethanol
C) 15 molecules of ethanol
D) 20 molecules of ethanol

Answer 1

B) 10 molecules of ethanol are produced.

Step-by-step explanation:

The balanced equation for the reaction is:

C2H5OH + 3O2 → 2CO2 + 3H2O

From the balanced equation, we can see that for every molecule of ethanol (C2H5OH) that reacts, 2 molecules of carbon dioxide (CO2) and 3 molecules of water (H2O) are produced. Therefore, the correct answer is B) 10 molecules of ethanol are produced.
