Question

In the unbalanced formula equation CO + O₂ → CO₂ + energy, energy

a. Is absorbed.
b. Can be considered a reactant.
c. Is released.
d. Both (a) and (b)

Answer 1

In the chemical reaction CO + O2 → CO2 + energy, energy is released, indicating that it is an exothermic reaction.

Step-by-step explanation:

In the unbalanced formula equation CO + O2 → CO2 + energy, energy is involved in the chemical reaction. When we see energy listed on the product side of a chemical equation, it implies that energy is released as the reaction proceeds. This type of reaction is known as an exothermic reaction. Hence, in the given reaction, as carbon monoxide (CO) reacts with oxygen (O2) to form carbon dioxide (CO2), energy is released into the surroundings, indicating an exothermic process. In contrast, an endothermic reaction would require energy to be absorbed from the surroundings, and energy would be listed as a reactant.
