The reaction above takes place in a closed system. What is true about the mass of the nitrogen atoms in this reaction?
A.
The mass of the nitrogen atoms in the reactants is greater than the mass of the nitrogen atoms in the products.
B.
The mass of the nitrogen atoms decreases in the reactants and increases in the products.
C.
The mass of the nitrogen atoms increases in the reactants and decreases in the products.
D.
The mass of the nitrogen atoms in the reactants is equal to the mass of the nitrogen atoms in the products.

D. The mass of the nitrogen atoms in the reactants is equal to the mass of the nitrogen atoms in the products.
Explanation: In a closed system atoms are neither created nor destroyed (law of conservation of mass). The nitrogen atoms present as N2 are simply rearranged into NH3, so their total mass stays the same.
