Chapter 2, Problem 2.129P

(a)

Interpretation Introduction

Interpretation:

The correct scenes that represent a mixture that fills a container is to be determined.

Concept introduction:

A mixture consists of a combination of two or more compounds or elements or compounds and elements which are physically intermingled. The components of a mixture are not chemically bonded to each other. The components of a mixture do not lose their individual identity. The components of a mixture are not chemically bonded to each other. Therefore, the mixture components can be separated using the physical methods.

(b)

Interpretation Introduction

Interpretation:

The scenes that represent a substance that cannot be broken down into simpler ones, are to be determined.

Concept introduction:

An element can be defined as the simplest type of matter which is composed of only one kind of atom. Hence elements can be represented by symbols. Elements cannot be broken down into simpler substances by any chemical or physical means. Examples are carbon, hydrogen, oxygen, sulfur, chlorine, etc.

(c)

Interpretation Introduction

Interpretation:

The scenes that represent an element with very high resistance to flow are to be determined.

Concept introduction:

An element can be defined as the simplest type of matter which is composed of only one kind of atom. Hence elements can be represented by symbols. Elements cannot be broken down into simpler substances by any chemical or physical means. Examples are carbon, hydrogen, oxygen, sulfur, chlorine, etc.

(d)

Interpretation Introduction

Interpretation:

The scenes that represent a homogenous mixture, are to be determined

Concept introduction:

A mixture consists of a combination of two or more compounds or elements or compounds and elements which are physically intermingled. The components of a mixture are not chemically bonded to each other.

Mixtures can be classified as homogenous and heterogeneous mixtures. Homogenous mixtures are those which have a uniform composition. The components of a homogenous mixture cannot be seen separately through the eyes. Heterogeneous mixtures do not have a uniform composition. The components of a heterogeneous mixture can be seen separately and hence can be easily separated.

(e)

Interpretation Introduction

Interpretation:

The scenes that represent an element that conforms to the walls of its container and displays an upper surface are to be determined.

Concept introduction:

An element can be defined as the simplest type of matter which is composed of only one kind of atom. Hence elements can be represented by symbols. Elements cannot be broken down into simpler substances by any chemical or physical means. Examples are carbon, hydrogen, oxygen, sulfur, chlorine, etc.

(f)

Interpretation Introduction

Interpretation:

The scenes that represent a gas that consists of diatomic particles are to be determined.

Concept introduction:

The matter is anything that has mass and occupies space. The three states of matter are as follows:

Solids – Solids are those substances in which the constituent particles are tightly packed. Solids have a fixed shape and volume.

Liquids – Liquids are those substances in which the constituent particles are loosely packed compared to those of the solids but tighter than those of the gases. Liquids take the shape of the container they fill.

Gases – Gases are those substances in which the constituent particles are free to move around. Gases neither have a definite shape nor a definite volume.

(h)

Interpretation Introduction

Interpretation:

The scene that represents a substance with a $2:1$ ratio of its component atoms is to be determined.

Concept introduction:

The law of definite composition - This law can be defined as; a particular compound maintains an exact universal proportion of elements in its composition, irrespective of the source. The proposal for this law was made by Joseph Proust.

(i)

Interpretation Introduction

Interpretation:

The scenes that represent a  matter that can be separated into its component substances by physical means, are to be determined.

Concept introduction:

A mixture consists of a combination of two or more compounds or elements or compounds and elements which are physically intermingled. The components of a mixture are not chemically bonded to each other. The components of a mixture do not lose their individual identity. The components of a mixture are not chemically bonded to each other. Therefore, the mixture components can be separated using the physical methods.

(j)

Interpretation Introduction

Interpretation:

The scene that represents a heterogeneous mixture is to be determined.

Concept introduction:

A mixture consists of a combination of two or more compounds or elements or compounds and elements which are physically intermingled. The components of a mixture are not chemically bonded to each other.

Mixtures can be classified as homogenous and heterogeneous mixtures. Homogenous mixtures are those which have a uniform composition. The components of a homogenous mixture cannot be seen separately through the eyes. Heterogeneous mixtures do not have a uniform composition. The components of a heterogeneous mixture can be seen separately and hence can be easily separated.

(k)

Interpretation Introduction

Interpretation:

The scenes that represent matter that obeys the law of definite composition are to be determined.

Concept introduction:

The law of definite composition - This law can be defined as; a particular compound maintains an exact universal proportion of elements in its composition, irrespective of the source. The proposal for this law was made by Joseph Proust.
