When Acetylene, C₂H₂, a Fuel Used in Welding, Is Burned

Multiple Choice

When acetylene, C₂H₂, a fuel used in welding, is burned in air, two molecules of acetylene combine with five oxygen molecules to form four CO₂ molecules and two H₂O molecules. Select the statement below that is incorrect in regard to this reaction.

A) The balanced equation for the reaction is 2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O.
B) If 8 acetylene molecules react, 12 CO₂ molecules should form.
C) If 12 H₂O molecules are formed, then 30 O₂ molecules must have reacted.
D) If 12 CO₂ molecules are formed, then 6 H₂O molecules should also form.
E) If 24 ethanol molecules react, then 60 oxygen molecules must also react
