The correct statement regarding the chemical equation \(4FeS + 7O_2 → 2Fe_2O_3 + 4SO_2\) is:
**It is balanced because the mass of the reactants equals the mass of the products.**
Chemical equations are balanced when the number of atoms for each element is the same on both sides of the equation, which ensures that the mass is conserved. In this case, the coefficients (4, 7, 2, and 4) ensure that all atoms are accounted for, confirming that it is balanced.
