Exploring Types of Chemical Reactions

Which type of reaction involves two or more elements or compounds combining to form a more complex substance?

• Synthesis

• Single Replacement

• Double Replacement

• Decomposition

In a synthesis reaction, what is the general form of the chemical equation?

• A + B → AB

• AB → A + B

• AB + C → AC + B

• AB + CD → AD + CB

What happens to compounds in a decomposition reaction?

• Different atoms in two compounds trade places.

• One element replaces another in a compound.

• They break down into simpler substances.

• They combine to form a more complex substance.

Which of the following is an example of a decomposition reaction?

• AB + CD → AD + CB

• AB → A + B

• A + B → AB

• AB + C → AC + B

In a single replacement reaction, what occurs?

• One element replaces another in a compound.

• Different atoms in two compounds trade places.

• A compound breaks down into simpler substances.

• Two elements combine to form a compound.

Which of the following represents a single replacement reaction?

• AB + CD → AD + CB

• AB + C → AC + B

• AB → A + B

• A + B → AB

Which type of reaction is represented by the equation AB + C → AC + B?

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

What happens in a double replacement reaction?

• One element replaces another in a compound.

• Different atoms in two compounds trade places.

• Two elements combine to form a compound.

• A compound breaks down into simpler substances.

Which of the following is an example of a double replacement reaction?

• A + B → AB
