Which compound contains covalent bonds? A. CaBr2CaBr2 B. FeS2FeS2 C. ZnF2ZnF2 D. CO2

The compound that contains covalent bonds is D. CO2.

Here's why:

Covalent bonds are formed when two atoms share electrons. This usually happens between non-metal atoms.

A. CaBr2 - This is an ionic compound formed between the metal Calcium (Ca) and the non-metal Bromine (Br). B. FeS2 - This is also an ionic compound formed between the metal Iron (Fe) and the non-metal Sulfur (S). C. ZnF2 - This is another ionic compound formed between the metal Zinc (Zn) and the non-metal Fluorine (F).

D. CO2 - This is a covalent compound. It is formed between the non-metal Carbon (C) and the non-metal Oxygen (O). Since both are non-metals, they form a covalent bond by sharing electrons.
