Question

Predict whether each of the following oxides is ionic or molecular: SnO2, Al2O3, CO2, Li2O, Fe2O3, H2O

Answer 1

Answer:

Explanation:

Ionic compounds are formed by combining a metal and a nonmetal.

Molecular compounds are formed by two or more nonmetals.

Answer 2

Answer:

SnO2, Fe2O3,Al2O3,Li2O- ionic

CO2,H2O- molecular

Explanation:

Ionic oxides are formed between oxygen and a metal. The bonds of oxygen to nonmetallic elements often lead to the formation of molecular oxides as seen above.
