Question

Please helppp!!!

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?
O O2(g) as a product
O O2(g) as a reactant
O O(g) as a product
O 20(g) as a reactant

Answer 1

Answer: B. O₂(g) as a reactant

Answer 2

O₂(g) as a reactant

Further explanation

In chemical reactions, there is a reaction between reagents and products

Reaction:

aA + bB ⇒ cC

Substances A and B are called a reactants

Substance C is called a product

In the above reaction:

• Reactants: C, O₂ and CO
• Products: CO and CO₂

CO functions as a product in the first reaction and functions as a reactant in the second reaction

In the final chemical equation :

CO(g)+30₂(g) → CO₂(g)

O₂ is on the left so it is called the reactant
