Responses

Each element has the same subscript or coefficient on each side.
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 sum of the coefficients and subscripts is the same on both sides.

The number of atoms of each element is the same on both sides.
The number of atoms of each element is the same on both sides.

The number of reactants is equal to the number of products.

Answer 1

The correct response is:

**The number of atoms of each element is the same on both sides.**

This statement reflects the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. In the balanced equation \(4Fe + 3O_2 \rightarrow 2Fe_2O_3\), the number of iron (Fe) atoms and oxygen (O) atoms is the same on both the reactant and product sides.
