Question

Consider the following intermediate chemical equations.

C(s) +202(g) → CO(g)
CO(g)+302(g) → CO2(g)
How will oxygen appear in the final chemical equation?
a) O2(g) as a product
b) O2(g) as a reactant
c) O O(g) as a product
d) 2O(g) as a reactant

Answer 1

The 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 option b) O2(g) as a reactant. In the given intermediate chemical equations, the oxygen is initially present as a reactant and is not fully consumed in the reactions. It remains as a reactant in the final equation.
