If a chemical equation has 2 oxygen atoms on the reactant side and 1 oxygen atom on the product side, what is the equation?
Answer and explanation
Correct answer: Unbalanced
In a balanced chemical equation, the number of atoms of each element must be the same on the reactant and product sides. Here, there are 2 oxygen atoms on the left and 1 on the right, so the equation is unbalanced. Option B is incorrect because oxygen atoms, too, must be equal on both sides of a balanced equation.
