The reaction takes place in a closed system. What is true about the carbon atoms in the reaction?

Question

A.
The total mass of the carbon atoms is the same as the total mass of the iron atoms.
B.
The mass of the carbon atoms increases between the reactants and the products of the reaction.
C.
The mass of carbon atoms in the reactants is the same as the mass of carbon atoms in the products.
D.
The total mass of the carbon atoms is the same as the total mass of the oxygen atoms.

Answer 1

The correct answer is:

C. The mass of carbon atoms in the reactants is the same as the mass of carbon atoms in the products.

This statement is true due to the law of conservation of mass, which states that in a closed system, the total mass of reactants must equal the total mass of products. Thus, the mass of specific atoms, such as carbon, must also remain constant throughout the reaction.
