If a chemical equation has the same number of hydrogen atoms on both sides but an unequal number of oxygen atoms, what is the correct conclusion?
Answer and explanation
Correct answer: The equation is unbalanced
A chemical equation is balanced only when the number of atoms of every element is equal on the reactant and product sides. Here, hydrogen is balanced but oxygen is not, so the equation is unbalanced. Option A is incorrect because balancing only one element is not sufficient.
