Chapter 5, Problem 5.56P

Interpretation Introduction

(a)

Interpretation:

To use the color indicators of the molecules and find out the reactants and products

Concept Introduction:

When two reactants add or combine, it forms products and the reaction is a combination reaction.

When a compound breaks down into two or more products, it is said to be a decomposition reaction.

Interpretation Introduction

(b)

Interpretation:

To illustrate the molecular art into a balanced equation

Concept Introduction:

Chemical reaction represents a combination or decomposition of reactants to give new products. The reactions are represented by chemical symbols that represent the elements and compounds with a specific formula.

Interpretation Introduction

(c)

Interpretation:

To classify the reaction as a combination, decomposition, single replacement, double replacement.

Concept Introduction:

When two or more reactants combine to form new products, it is a combination reaction. When the reactant breaks down into two or more new products, it is decomposition. A reaction in which one element reacting with a compound replaces one element in that compound, then it is said to be a single-replacement reaction. A reaction in which the positive ions and the negative ions of the two reactants switch places forming new compounds or products is said to be double displacement reaction.
