At high temperatures, ammonium nitrate decomposes into water vapor and nitrous oxide. One molecule of ammonium nitrate produces two molecules of water and one molecule of nitrous oxide. Ball-and-stick models of nitrous oxide and water molecules are shown.

GPT-4o mini · Answer

To determine the number of hydrogen, nitrogen, and oxygen atoms in a molecule of ammonium nitrate (NH4NO3), we can analyze its chemical formula.

The structure of ammonium nitrate is made up of:

Ammonium ion (NH4+) which contains:
- 4 hydrogen (H) atoms
- 1 nitrogen (N) atom
Nitrate ion (NO3-) which contains:
- 3 oxygen (O) atoms
- 1 nitrogen (N) atom

By combining these, we can find the total number of each type of atom in a molecule of ammonium nitrate:

Total Nitrogen atoms = 1 (from NH4) + 1 (from NO3) = 2 nitrogen atoms.
Total Hydrogen atoms = 4 (from NH4) = 4 hydrogen atoms.
Total Oxygen atoms = 3 (from NO3) = 3 oxygen atoms.

Now we fill in the table:

| Ammonium Nitrate Molecule | Number of Hydrogen Atoms | Number of Oxygen Atoms | Number of Nitrogen Atoms | |---------------------------|--------------------------|------------------------|--------------------------| | | 4 | 3 | 2 |

So the final answer is:

Number of Hydrogen Atoms: 4
Number of Oxygen Atoms: 3
Number of Nitrogen Atoms: 2
