Transcript text: Identify the sentence below that describes this reaction:
\[
2 \mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2}(\mathrm{~s}) \rightarrow 2 \mathrm{BaO}(\mathrm{s})+2 \mathrm{~N}_{2}(\mathrm{~g})+2 \mathrm{O}_{2}(\mathrm{~g})
\]
a. The decomposition of solid barium nitrate leads to the formation of solid barium oxide, diatomic nitrogen gas, and diatomic oxygen gas.
b. The decomposition of solid barium nitrate leads to the formation of solid barium oxide, nitrogen gas atom, and an oxygen gas atom.
c. The decomposition of solid barium nitrogen oxygen leads to the formation of solid barium oxygen, diatomic nitrogen gas, and diatomic oxygen gas.
d. The decomposition of solid barium (II) nitrate leads to the formation of solid barium (II) oxide, diatomic nitrogen gas, and diatomic oxygen gas.
e. The decomposition of solid barium nitrite leads to the formation of solid barium oxide, diatomic nitrogen gas, and diatomic oxygen gas.
This reaction involves the decomposition of barium nitrate (\(\mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2}\)) into barium oxide (\(\mathrm{BaO}\)), nitrogen gas (\(\mathrm{N}_{2}\)), and oxygen gas (\(\mathrm{O}_{2}\)).
Step 2: Evaluate Each Sentence
Option a: Correctly describes the decomposition of solid barium nitrate into solid barium oxide, diatomic nitrogen gas, and diatomic oxygen gas.
Option b: Incorrectly describes the products as nitrogen gas atom and oxygen gas atom, which should be diatomic molecules.
Option c: Incorrectly names the reactant as barium nitrogen oxygen instead of barium nitrate.
Option d: Correctly describes the decomposition of solid barium (II) nitrate into solid barium (II) oxide, diatomic nitrogen gas, and diatomic oxygen gas.
Option e: Incorrectly names the reactant as barium nitrite instead of barium nitrate.
Step 3: Determine the Correct Sentence
Both options a and d correctly describe the reaction. However, option d provides a more precise chemical nomenclature by specifying "barium (II) nitrate" and "barium (II) oxide."
Final Answer
\(\boxed{\text{d. The decomposition of solid barium (II) nitrate leads to the formation of solid barium (II) oxide, diatomic nitrogen gas, and diatomic oxygen gas.}}\)
