Question

consider the unbalanced equation for the oxidation of butene. c4h8 + 6o2 → 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 two water molecules two carbon dioxide molecules and four water molecules four carbon dioxide molecules and two water molecules

Explanation:

Step1: Balance the chemical equation

$C_4H_8 + 6O_2
ightarrow 4CO_2+4H_2O$

Step2: Analyze the stoichiometry

From the balanced equation, for 1 molecule of $C_4H_8$, 4 molecules of $CO_2$ and 4 molecules of $H_2O$ are produced.

Answer:

B. four carbon dioxide molecules and four water molecules
