question 1
1 pts
one molecule of oxygen gas contains:
a nonpolar covalent bond
a polar covalent bond
a partial negative charge on each o atom
both ionic and covalent bonds

Explanation:

Oxygen gas (\(O_2\)) has a bond between two oxygen atoms. Since the atoms are identical, the electronegativity difference is zero. A nonpolar covalent bond occurs when electrons are shared equally between atoms with no electronegativity difference. A polar covalent bond requires a significant electronegativity difference (not present here). Oxygen atoms in \(O_2\) don't have partial charges (as sharing is equal), and \(O_2\) has only covalent, not ionic, bonds. So the correct option is the one with a nonpolar covalent bond.

Answer:

A. a nonpolar covalent bond
