In which situation will a chemical equation not be considered balanced?
Answer and explanation
Correct answer: When the number of atoms of even one element differs on the two sides
According to the law of conservation of mass, a balanced chemical equation has the same number of atoms of each element on the reactant and product sides. If the number of atoms of even one element differs, the equation is unbalanced. Options C and D only state the usual arrangement for writing an equation; they do not by themselves establish that it is balanced.
