Chapter 1, Problem 19P

Classify each example of molecular art as a pure element, a pure compound, or a mixture.

Interpretation Introduction

(a)

Interpretation:

Whether the given molecular art is a pure compound, mixture, or a pure element needs to be classified.

  

Concept Introduction:

An element is known as the pure substance that cannot be broken down further using chemical methods. The methods are such as electrolysis, cooling, heating, and reactions with other chemical substances.

A compound is known as the pure substance which is made up of more than two different atoms that are bonded chemically to one another. Using chemical methods, a compound can be destroyed. It can be broken down into simpler compounds or into its elements.

A mixture is the combination of more than two dissimilar elemental substances or compounds. The mixture is not a pure substance, but it is the combination of different atoms of elements. Mixtures are of two kinds, Heterogenous and Homogeneous.

Answer to Problem 19P

Molecular art 'a' − Pure element.

Explanation of Solution

As per the definitions of element, compound and mixture:

The pure element is the substance that doesn't separate into simple substances through the chemical procedures.

A pure compound is a substance formed by combinations of two or more elements.

A mixture is made up of the combination of one or more components with several compositions.

Now, based on these definitions, molecular art (a) signifies pure elements.

Interpretation Introduction

(b)

Interpretation:

Whether the below molecular art is pure compound, mixture, or a pure element needs to be determined.

Answer to Problem 19P

Molecular art 'b' − Pure compounds

Explanation of Solution

As per the definitions of element, compound and mixture:

The pure element is the substance that doesn't separate into simple substances through the chemical procedures.

A pure compound is a substance formed by combinations of two or more elements.

A mixture is made up of the combination of one or more components with several compositions.

Now based on these definitions, molecular art (b) signifies pure compounds.
