Final Answer:
The correct classification of the given compounds is: B) Ionic, Molecular, Ionic, Ionic, Ionic, Ionic, Molecular, Ionic, Molecular, Molecular, Molecular
Step-by-step explanation:
Ionic compounds typically consist of a metal combined with a non-metal, while molecular compounds involve non-metals bonded together. To classify these compounds, consider the elements involved and their typical bonding patterns.
C₂H₄ (Ethylene) is a molecular compound as it consists of non-metallic elements, carbon, and hydrogen bonded together.
H₂O (Water) is a molecular compound made of hydrogen and oxygen.
K₂S (Potassium sulfide) is an ionic compound with a metal (potassium) and a non-metal (sulfur).
CaF₂ (Calcium fluoride) is an ionic compound, formed by a metal (calcium) and a non-metal (fluorine).
Li₂Se (Lithium selenide) is an ionic compound formed by a metal (lithium) and a non-metal (selenium).
Cs₃N (Cesium nitride) is an ionic compound with a metal (cesium) and a non-metal (nitrogen).
N₂O (Nitrous oxide) is a molecular compound composed of nitrogen and oxygen.
NaBr (Sodium bromide) is an ionic compound containing a metal (sodium) and a non-metal (bromine).
NH₃ (Ammonia) is a molecular compound made of nitrogen and hydrogen.
BaSe (Barium selenide) is a molecular compound composed of barium and selenium.
SO₃ (Sulfur trioxide) is a molecular compound consisting of sulfur and oxygen.
CO₂ (Carbon dioxide) is a molecular compound formed by carbon and oxygen.
The classification involves identifying the bonding between the elements in each compound, distinguishing ionic bonds (between metals and non-metals) from molecular bonds (between non-metals). This approach helps determine whether the compound is ionic or molecular based on the elements involved and their bonding patterns.
