Question

Consider the following intermediate chemical equations: C₅ + O₂ → CO, CO + O₂ → CO₂. How will oxygen appear in the final chemical equation?*

a) O₂(g) as a product
b) O₂(g) as a reactant
c) O₂(g) as a product
d) 2O(g) as a reactant

Answer 1

Oxygen will appear in the final chemical equation as O₂(g) as a reactant.

Step-by-step explanation:

The oxygen will appear in the final chemical equation as O₂(g) as a reactant. In the given intermediate chemical equations, oxygen is consumed as a reactant in the first equation (C₅ + O₂ → CO) and then regenerated as a product in the second equation (CO + O₂ → CO₂). Therefore, in the final chemical equation, oxygen will still be present as a reactant.
