Question

consider the same reaction:
1 molecule of nitrogen (n₂) reacts with 1 molecule of oxygen (o₂) to produce some amount of nitric oxide (no).
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
o	2	2

during this reaction, how many molecules of nitric oxide (no) are produced?

Explanation:

Step1: Analyze the formula of NO

Each NO molecule has 1 N atom and 1 O atom.

Step2: Calculate the number of NO molecules from N atoms

We have 2 N atoms in products. Since each NO has 1 N atom, the number of NO molecules from N atoms is $2\div1 = 2$.

Step3: Verify with O atoms

We have 2 O atoms in products. Since each NO has 1 O atom, the number of NO molecules from O atoms is $2\div1 = 2$. Both give the same result.

Answer:

2
