Decomposition Reactions in Chemistry

The video tutorial explains the decomposition reaction of potassium nitrate (KNO3) breaking down into potassium nitrite (KNO2) and oxygen (O2). It describes the general pattern of decomposition reactions, where a compound breaks apart into two or more products. The video also mentions the need to balance the chemical equation and provides a link for further assistance. The tutorial concludes with closing remarks from Dr. B.

What type of reaction is demonstrated when KNO3 breaks down into KNO2 and O2?

• Synthesis reaction

• Decomposition reaction

• Double replacement reaction

• Single replacement reaction

In a decomposition reaction, a compound AB typically breaks down into which of the following?

• AB + B

• A + BC

• AB + C

• A + B

What is the general pattern of a decomposition reaction?

• A + B -> C

• AB + C -> AC + B

• AB -> A + B

• A + B -> AB

Which of the following is true about the reaction of KNO3 breaking down into KNO2 and O2?

• It is a balanced reaction.

• It is a synthesis reaction.

• It is a decomposition reaction.

• It is a single replacement reaction.
