Question

The reactants of a chemical equation are 3H2 and N2. Which set of atoms must make up the equation's products so that the equation models the law of conservation of mass?

A) 8 H and 2 Na
B) 2 H and 2 Na
C) 6 H and 2 N
D) 4 Hg and 3 N

Answer 1

Option C) 6 H and 2 N is correct for the chemical equation to model the law of conservation of mass with the reactants 3H2 and N2, as it accurately reflects the number of atoms conserved in the production of ammonia.

Step-by-step explanation:

The correct set of atoms that must make up the equation's products to model the law of conservation of mass with the reactants 3H2 and N2 is option C) 6 H and 2 N.

According to the law of conservation of mass, the number of atoms of each element must be the same in the reactants and the products. The balanced chemical reaction for the production of ammonia (NH3) from hydrogen (H2) and nitrogen (N2) gases is N2 + 3H2 → 2NH3, which shows that six hydrogen atoms and two nitrogen atoms are conserved during the reaction.
