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) if 12 CO2 molecules are formed, then six H2O molecules will also be formed.
B) if eight acetylene molecules react, 12 CO2 molecules will be formed.
C) the balanced equation for the reaction is 2C2H2 + 5O2 → 4CO2 + 2H2O.
D) If 12 H2O molecules are formed, then 30 O2 molecules must have reacted.
