a) SO2 acidic b) Na2O basic c) CO2 acidic d) CaO basic e) no correct answer -wrong
No, it will form a basic solution of Sodium Hydroxide as per the following equation. Na2O + H2O ---> 2NaOH As the solution will have OH- ions so it will be basic. Na2O is a basic oxide and basic oxide dissolve in water to form bases( here NaOH). Acidic oxides dissolves in water to form acids. Alkali metal(group 1 of periodic table) oxides are always basic oxides, but all metal oxides may not be basic( some transition metal oxides are acidic).
Yes, certain metal oxides, mostly from the middle groups of the transition metals are acidic. Chromium and rhenium, for example, both form oxides which are acidic in water.
barium oxide is basic oxide.As Barium is a metal so metal forms basic oxide.

Most metal hydroxides and oxides e.g. K2O and KOH
alloy
Yes. Metals can be dissolved into liquid solutions. Several metals can be dissolved in acidic media such as HNO3 to prepare acidic solutions of these metals.
A metal solution is an alloy.
