Question

pay attention to the types of molecules being addressed here in this part of the reading. binary molecular compounds are molecules composed of two nonmetal elements. which of the following are binary molecular compounds? no₂ libr so₂ co₂ cacl₂

Explanation:

Binary molecular compounds are composed of two non - metal elements.

• \(NO_2\): Nitrogen (\(N\)) and oxygen (\(O\)) are non - metals.
• \(LiBr\): Lithium (\(Li\)) is a metal, so \(LiBr\) is not a binary molecular compound.
• \(SO_2\): Sulfur (\(S\)) and oxygen (\(O\)) are non - metals.
• \(CO_2\): Carbon (\(C\)) and oxygen (\(O\)) are non - metals.
• \(CaCl_2\): Calcium (\(Ca\)) is a metal, so \(CaCl_2\) is not a binary molecular compound.

Answer:

\(NO_2\), \(SO_2\), \(CO_2\)
