Matching Oxides with their Hydrates:

To match the formulas of oxides with the names of their corresponding hydrates, we need to understand the chemical formulas and nomenclature of both oxides and hydrates. Let's go through each oxide and its corresponding hydrate:

1. SO3: - The formula SO3 represents sulfur trioxide. - To find the corresponding hydrate, we need to add water (H2O) to the oxide. - The resulting compound is sulfur trioxide hydrate, which can be written as H2SO4. - Therefore, the matching hydrate for SO3 is sulfuric acid (H2SO4).

2. N2O5: - The formula N2O5 represents dinitrogen pentoxide. - To find the corresponding hydrate, we need to add water (H2O) to the oxide. - The resulting compound is dinitrogen pentoxide hydrate, which can be written as HNO3. - Therefore, the matching hydrate for N2O5 is nitric acid (HNO3).

3. K2O: - The formula K2O represents potassium oxide. - To find the corresponding hydrate, we need to add water (H2O) to the oxide. - The resulting compound is potassium oxide hydrate, which can be written as KOH. - Therefore, the matching hydrate for K2O is potassium hydroxide (KOH).

Now, let's match the formulas of the oxides with the names of their corresponding hydrates:

A) SO3 matches with sulfuric acid (H2SO4). B) N2O5 matches with nitric acid (HNO3). C) K2O matches with potassium hydroxide (KOH).
