Chapter 11.2, Problem 22LC

(a)

Interpretation Introduction

Interpretation: To determine the aqueous solution of two ionic compounds.

Concept Introduction: When more than one atom or molecule will get combined, they will form a different kind of atom or molecule. This process is named a chemical reaction.

Answer to Problem 22LC

Double displacement reaction

Explanation of Solution

When two chemicals interact by transferring ions, a double displacement reaction occurs, creating two new molecules. In the twofold displacement process, positive ions trade places with negative ions. In water-soluble ionic compounds, numerous double displacement reactions take arise.

(b)

Interpretation Introduction

Interpretation: To determine the type of chemical reaction.

Concept Introduction: When more than one atom or molecule will get combined, they will form a different kind of atom or molecule. This process is named a chemical reaction.

Answer to Problem 22LC

Decomposition reaction

Explanation of Solution

In a decomposition reaction, a single compound decomposes to form two or more compounds.

(c)

Interpretation Introduction

Interpretation: To determine the type of chemical reaction.

Concept Introduction: When more than one atom or molecule will get combined, they will form a different kind of atom or molecule. This process is named a chemical reaction.

Answer to Problem 22LC

Combination reaction

Explanation of Solution

When more than two atoms get combined and produced a different kind of product is named a combination reaction.

(d)

Interpretation Introduction

Interpretation: To determine the type of chemical reaction.

Concept Introduction: When more than one atom or molecule will get combined, they will form a different kind of atom or molecule. This process is named a chemical reaction.

Answer to Problem 22LC

Combustion reaction

Explanation of Solution

When a chemical reacts with oxygen gas, combustion occurs, and it produces energy in the form of heat and light ${\text{O}}_{\text{2}}$ must be one of the reactants in the combustion processes.
