Question
The balanced chemical equation shows a reaction between iron (Fe) and oxygen (O2).
4Fe + 302 → 2Fe2O3
How does the equation show the law of conservation of mass?
(1 point)
• Each element has the same subscript or coefficient on each side.
• The sum of the coefficients and subscripts is the same on both sides.
• The number of reactants is equal to the number of products.
• The number of atoms of each element is the same on both sides.

The correct answer is:
• The number of atoms of each element is the same on both sides.
This reflects the law of conservation of mass, which states that in a chemical reaction, the mass of the reactants must equal the mass of the products, meaning the number of atoms for each element must remain constant throughout the reaction.
