A proper formula for a type of Iron Oxide is F2O3. What is the charge of the Iron (Fe) cation in this formula? A.) Fe^3+
B.) Fe^2+
C.) Fe^2-
D.) F^3-

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
