Question
Potassium (K) is a silvery metal that reacts violently with water. Chlorine (Cl) is a poisonous greenish gas. The compound KCl is likely to:be silvery greenreact violently with waterbe a metallic gashave its own set of properties
Solution
The compound KCl, also known as potassium chloride, is likely to have its own set of properties. When elements combine to form a compound, the compound often has different properties than the individual elements that make it up.
In this case, potassium is a silvery metal that reacts violently with water, and chlorine is a poisonous greenish gas. However, when they combine to form potassium chloride, the resulting compound is a white crystalline solid that is often used in medicine and scientific applications. It does not react violently with water like potassium, nor is it a poisonous gas like chlorine.
So, the properties of KCl are different from the properties of its constituent elements, K and Cl. This is a common phenomenon in chemistry known as emergence, where the whole (the compound) has different properties than the sum of its parts (the individual elements).
