Question

Consider the unbalanced equation for the oxidation of butene. C4H8 + 6O2 mc022-1.jpg CO2 + H2O For each molecule of C4H8 that reacts, how many molecules of carbon dioxide and water are produced? two carbon dioxide molecules and two water molecules four carbon dioxide molecules and four water molecules two carbon dioxide molecules and four water molecules four carbon dioxide molecules and two water molecules

Answer 1

The answer is "four carbon dioxide molecules and four water molecules".

if we balance the equation:
C₄H₈ + 6O₂→CO₂ + H₂O 
C₄H₈ + 6O₂→ 4CO₂ + 4H₂O
Now you see in balanced equation there are four carbon dioxide molecules and four water molecules produced.
