(a)
Interpretation: The contents given should be classified as elements only, compounds only, or elements and compounds.
Concept Introduction: An element is a substance that cannot be broken down into simpler formats. Compounds are substances made up of two or more different chemical elements combines in a fixed ratio.
(a)
Answer to Problem 13STP
The contents in this group can be classified as elements and compounds.
Explanation of Solution
It contains two different types of single balls representing elements and three combined balls denoting compounds.
(b)
Interpretation: The contents given should be classified as elements only, compounds only, or elements and compounds.
Concept Introduction: An element is a substance that cannot be broken down into simpler formats. Compounds are substances made up of two or more different chemical elements combines in a fixed ratio.
(b)
Answer to Problem 13STP
This group of contents can be classified as elements only.
Explanation of Solution
It contains only single balls indicating pure elements, hence it can be classified as elements only.
(c)
Interpretation: The contents given should be classified as elements only, compounds only, or elements and compounds.
Concept Introduction: An element is a substance that cannot be broken down into simpler formats. Compounds are substances made up of two or more different chemical elements combines in a fixed ratio.
(c)
Answer to Problem 13STP
It is an element-only group containing only one type of atom.
Explanation of Solution
The single balls represent pure elements, hence it contains elements only.
(d)

(d)
Answer to Problem 13STP
It is a compound-only group.
Explanation of Solution
It contains combined balls representing triatomic compounds. So it is a compounds-only group.
