Can acidic oxide react with acids?
If not, why?

no

Explanation:

Acidic oxides, or acid anhydride, are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetals or of metals in high oxidation states.

The answer is no!

Acidic oxides, or acid anhydride, are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetals or of metals in high oxidation states.

The molecules in 2,14 mol CO is 1, 29 x 10 ^ 24. See the explanation below, please.

Explanation:

We use the number of Avogadro:

1 mol 6, 02 x10  ^23 molecules

2,14 mol x =(2,14 mol x6, 02 x10  ^23 molecules )/ 1mol

x=1, 29 x 10 ^ 24 molecules
