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.\nwater molecule\nnitrous oxide\ngiven that mass is conserved in chemical reactions, how many hydrogen, nitrogen, and oxygen atoms are there in a molecule of ammonium nitrate? move numbers to their correct places in the table.\nammonium nitrate molecule\nnumber of hydrogen atoms number of oxygen atoms number of nitrogen atoms\n1 2 3 4 5
Answer
Explanation:
Step1: Write the decomposition reaction
The decomposition of ammonium nitrate ($NH_4NO_3$) is $NH_4NO_3\rightarrow 2H_2O + N_2O$.
Step2: Count atoms based on conservation
In the products, for hydrogen: In 2 molecules of $H_2O$, there are $2\times2 = 4$ hydrogen atoms. For nitrogen: In 1 molecule of $N_2O$, there are 2 nitrogen atoms. For oxygen: In 2 molecules of $H_2O$ there are 2 oxygen - atoms and in 1 molecule of $N_2O$ there is 1 oxygen - atom, so a total of $2 + 1=3$ oxygen atoms. Since mass is conserved, the number of each type of atom in the reactant (ammonium nitrate) is the same as in the products.
Answer:
| Number of Hydrogen Atoms | Number of Oxygen Atoms | Number of Nitrogen Atoms |
|---|---|---|
| 4 | 3 | 2 |
