Answer:

2CO(g) + O₂(g) → 2CO₂(g)

Step-by-step explanation:

What is a balanced chemical equation?

  • A balanced chemical equation is one that has equal number of atoms of each element involved in the reaction on both side of the equation.

How do we balance chemical equations?

  • Balancing chemical equations is a try and error process that involves putting appropriate coefficients on the reactants and products in a chemical reaction.

Why is it important to balance chemical equation?

  • Chemical equations are balanced so as to obey the law of conservation of mass.

In this case; the balanced chemical equation for the reaction between carbon monoxide and oxygen gas is given by;

2CO(g) + O₂(g) → 2CO₂(g)

  • This is because there are 2 carbon atoms and 4 oxygen atoms on both the reactant and product side.
