Which of the following compounds contains a metal?
In the world of chemistry, metals play a crucial role in various compounds, offering unique properties and applications. Identifying which compounds contain metals can be an intriguing task, as metals are often found in different forms and combinations. This article aims to explore and identify the compounds that contain metals among a list of given options.
The first compound to consider is sodium chloride (NaCl), commonly known as table salt. Although sodium is a metal, it forms an ionic bond with chlorine, resulting in a salt compound. Therefore, sodium chloride does not contain a metal in its molecular form.
Moving on to the second option, iron(III) oxide (Fe2O3), also known as rust. Iron is a metal, and in this compound, it is present in its +3 oxidation state. Thus, iron(III) oxide is a compound that contains a metal.
The third compound on the list is carbon dioxide (CO2). Carbon is a non-metal, and oxygen is also a non-metal. Therefore, carbon dioxide does not contain a metal.
Next, we have aluminum sulfate (Al2(SO4)3). Aluminum is a metal, and in this compound, it is present in its +3 oxidation state. Hence, aluminum sulfate is a compound that contains a metal.
The fifth compound is potassium nitrate (KNO3). Potassium is a metal, and in this compound, it is present in its +1 oxidation state. Therefore, potassium nitrate is a compound that contains a metal.
In conclusion, among the given compounds, iron(III) oxide, aluminum sulfate, and potassium nitrate contain metals. Identifying these compounds helps us understand the role of metals in various chemical reactions and their applications in everyday life.
