Question

Consider the following reaction. how many carbon dioxide molecules will be present once the reaction is complete if the initial reaction vessel contains 8 ch4 molecules and 6 oxygen molecules? (hint: is the equation balanced?)

CH₄ + O₂→ CO₂ + H₂O

Answer 1

The balanced equation is CH₄ + 2O₂ → CO₂ + 2H₂O. For every 1 methane molecule, we get 1 carbon dioxide molecule.

Therefore there will be 8 carbon dioxide molecules.

Step-by-step explanation:

The given reaction is: CH₄ + O₂ → CO₂ + H₂O.

To balance the equation, we need to have the same number of each type of atom on both sides. By balancing the equation, it becomes: CH₄ + 2O₂ → CO₂ + 2H₂O.

From the balanced equation, we can see that for every 1 methane molecule (CH₄), we get 1 carbon dioxide molecule (CO₂). Therefore, if we start with 8 methane molecules, there will be 8 carbon dioxide molecules once the reaction is complete.
