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

Explanation:

Step1: Write the balanced chemical equation

The reaction is $N_2 + 3H_2
ightarrow 2NH_3$.

Step2: Count nitrogen atoms in reactants

In 1 molecule of $N_2$, the number of nitrogen atoms is 2.

Step3: Count hydrogen atoms in reactants

In 3 molecules of $H_2$, since each $H_2$ has 2 hydrogen - atoms, the number of hydrogen atoms is $3\times2 = 6$.

Step4: Count nitrogen atoms in products

In 2 molecules of $NH_3$, the number of nitrogen atoms is 2.

Step5: Count hydrogen atoms in products

In 2 molecules of $NH_3$, since each $NH_3$ has 3 hydrogen - atoms, the number of hydrogen atoms is $2\times3=6$.

Answer:

Chemical element	Number of atoms in reactants	Number of atoms in products
H	6	6
