Formulas of Oxides for Given Elements

When creating the formulas for oxides of the given elements, it's important to consider that oxygen has a valency of II. Here are the formulas for the oxides of the specified elements:

1. NO (V): - The formula for the oxide of nitrogen with a valency of V is NO2.

2. AlO (II): - The formula for the oxide of aluminum with a valency of II is AlO.

3. Mn O (VII): - The formula for the oxide of manganese with a valency of VII is Mn2O7.

4. Ba O (0): - The formula for the oxide of barium with a valency of 0 is BaO.

5. SO (VI): - The formula for the oxide of sulfur with a valency of VI is SO3.

6. K O (1): - The formula for the oxide of potassium with a valency of 1 is K2O.

7. Pb O (IV): - The formula for the oxide of lead with a valency of IV is PbO2.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
