Question

A chemical reaction occurred in a closed container. Which is true of the equation of the reaction as shown below: N2 + 3H2 -> 2NH3

Option 1: A. The mass and molecules of the reactants equal the mass and molecules of the products.
Option 2: B. The volume and mass of the reactants equal the volume and mass of the products.
Option 3: C. The molecules and atoms of the reactants equal the molecules and atoms of the products.
Option 4: D. The atoms and mass of the reactants equal the atoms and mass of the products.

Answer 1

The molecules and atoms of the reactants equal the molecules and atoms of the products.

Step-by-step explanation:

In a chemical reaction, the equation represents the relationship between reactants and products. The given equation: N2 + 3H2 -> 2NH3 indicates that nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3).

Option 3: C. The molecules and atoms of the reactants equal the molecules and atoms of the products is the correct answer. This means that the number of molecules and atoms of each element in the reactants equals the number of molecules and atoms in the products according to the balanced chemical equation.
