Question

An acidic oxide is produced by the element ______.

Options

• Na

• C

• Ca

• H

Answer 1

An acidic oxide is produced by the element C.

Explanation:

Carbon (C) is a non-metal, and non-metals typically react with oxygen to form acidic oxides. When carbon dioxide (CO₂) dissolves in water, it reacts to produce carbonic acid (H₂CO₃). In contrast, sodium (Na) and calcium (Ca) are metals that form basic oxides, while hydrogen (H) forms water, which is a neutral oxide.
