Which of the following compounds contains a metal? A) CO B) LiCl C) HO D) CH; E) PBr,
The Correct Answer and Explanation is:
The correct answer is B) LiCl.
Here’s the explanation:
To identify which of these compounds contains a metal, let’s analyze each option:
A) CO (Carbon monoxide): This compound consists only of carbon (C) and oxygen (O), both of which are nonmetals. Therefore, CO does not contain a metal.
B) LiCl (Lithium chloride): Lithium chloride is made up of lithium (Li), which is an alkali metal, and chlorine (Cl), a nonmetal. Since lithium is a metal, LiCl contains a metal.
C) HO (Hydroxide): The hydroxide ion consists of oxygen (O) and hydrogen (H), both of which are nonmetals. Therefore, HO does not contain a metal.
D) CH4 (Methane): Methane consists only of carbon (C) and hydrogen (H), which are nonmetals. Hence, CH4 does not contain a metal.
E) PBr3 (Phosphorus tribromide): Phosphorus (P) and bromine (Br) are both nonmetals, so PBr3 does not contain a metal.
To summarize, LiCl is the only compound in the list that contains a metal, lithium, which is classified as an alkali metal in the periodic table.
