Chapter 11.2, Problem 20LC

Interpretation Introduction

Interpretation: To determine the type of chemical reactions.

Concept Introduction: When one kind of atom or molecule will be combined with another kind of chemical reaction, then it will be referred to as a chemical reaction.

Answer to Problem 20LC

There are five types of chemical reactions:

1. Decomposition reaction.
2. Double displacement reaction.
3. Displacement reaction.
4. Combination reaction.
5. Precipitation reaction.

Explanation of Solution

There are five types of chemical reactions:

1)Decomposition reaction:

When one type of molecule will break into smaller molecules, then it will be referred to as a decomposition reaction.

2) displacement reaction:

When one type of molecule is replaced by another type of molecule, then it will be referred to as a displacement reaction.

3) Double displacement reaction.

When more than one type of molecule is replaced by another type of molecule, then it will be referred to as a double displacement reaction.

4) Combination reaction.

One compound is created when two or more other chemicals are combined. This type of reaction is named a combination reaction.

5) Precipitation reaction:

When one or more molecules will react together, they will form a precipitate during the reaction, such type of reaction is named a Precipitation reaction.
