D. an unbalanced equation

Answer 1

The reaction \( 4\text{Fe} + 3\text{O}_2 \rightarrow 2\text{Fe}_2\text{O}_3 \) represents:

C. a conservation of atoms

In this equation, the number of atoms of each element on the reactant side (4 Fe and 6 O) is equal to the number of atoms of each element on the product side (4 Fe and 6 O). This illustrates the law of conservation of mass, which states that atoms are neither created nor destroyed in a chemical reaction.
