Question

consider the same reaction: 1 molecule of nitrogen (n₂) reacts with 3 molecules of hydrogen (h₂) to produce some amount of ammonia (nh₃). use the number of atoms in the products to answer the question below. chemical element number of atoms in reactants number of atoms in products h 6 6 n 2 2 during this reaction, how many molecules of ammonia (nh₃) are produced?

Explanation:

Step1: Analyze ammonia composition

Each ammonia ($NH_3$) molecule has 1 nitrogen atom and 3 hydrogen atoms.

Step2: Use nitrogen - atom count

There are 2 nitrogen atoms in the products. Since each $NH_3$ has 1 nitrogen atom, the number of $NH_3$ molecules based on nitrogen - atom count is 2.

Step3: Verify with hydrogen - atom count

Each $NH_3$ has 3 hydrogen atoms. With 2 $NH_3$ molecules, there are $2\times3 = 6$ hydrogen atoms, which matches the hydrogen - atom count in the products.

Answer:

2
