Question

ammonia is commonly used as a fertilizer for plants. it is made when nitrogen gas and hydrogen gas react under specific conditions.
consider the following reaction:
1 molecule of nitrogen (n₂) reacts with 3 molecules of hydrogen (h₂) to produce some amount of ammonia (nh₃).
to find the amount of ammonia produced, first determine the number of each type of atom in the products.
hint: during a chemical reaction, atoms are not created, destroyed, or changed from one chemical element to another.

chemical element	number of atoms in reactants	number of atoms in products
n	2

Explanation:

Step1: Apply law of conservation of mass

According to the law of conservation of mass, the number of atoms of each element in the reactants is equal to the number of atoms of that element in the products in a chemical reaction.

Step2: Determine hydrogen - atom count in products

Since there are 6 hydrogen atoms in the reactants (3 molecules of \(H_2\) with 2 hydrogen atoms per molecule), the number of hydrogen atoms in the products is 6.

Step3: Determine nitrogen - atom count in products

Since there are 2 nitrogen atoms in the reactant (\(N_2\)), the number of nitrogen atoms in the products is 2.

Answer:

Chemical element	Number of atoms in products
N	2
