To understand relative reactivities of metal oxides, it is important to understand their relative acidity. Arrange these metal oxides in order of decreasing acidity. Rank from highest to lowest acidity. To rank items as equivalent, overlap them.

ZnO,
Ni2O3,
V2O3,
Cu2O,
MnO

Answer:

MnO > Ni₂O₃ > ZnO> Cu₂O > V₂O₃

Explanation:

To answer this question you must know the smallest ion with the highest charge will be the most acidic. For the oxides:

ZnO: Charge Zn⁺²; radium: 74pm

Ni₂O₃: Charge Ni⁺³; radium: 74pm

V₂O₃: Charge V⁺³; radium: 78pm

Cu₂O: Charge Cu⁺¹; radium: 77pm

MnO: Charge Mn⁺²; radium: 70pm

As the smallest ion is Mn⁺², MnO will be the most acidic, then Ni₂O₃ because is the samllest ion with ZnO but has a highest charge, then Cu₂O and V₂O₃

The order is:

MnO > Ni₂O₃ > ZnO> Cu₂O > V₂O₃

I hope it helps!
