Single Replacement Reactions in Chemistry

This video tutorial explains the type of reaction between magnesium (Mg) and copper(II) sulfate (CuSO4), identifying it as a single replacement reaction. The video describes how magnesium, being more reactive, displaces copper from copper sulfate to form magnesium sulfate (MgSO4) and copper. The activity series is used to predict the feasibility of the reaction, highlighting magnesium's higher reactivity compared to copper. The tutorial concludes with a summary of the reaction process.

What type of reaction occurs when magnesium reacts with copper(II) sulfate?

• Single replacement reaction

• Double replacement reaction

• Synthesis reaction

• Decomposition reaction

In a single replacement reaction, what happens to the metal that is replaced?

• It is released as a gas

• It forms a new compound

• It remains in the solution

• It ends up by itself

What is the product formed when magnesium replaces copper in copper(II) sulfate?

• Copper oxide

• Magnesium sulfate

• Magnesium oxide

• Copper sulfate

Which of the following best describes a single displacement reaction?

• A compound breaks down into two or more elements

• Two compounds exchange elements

• One element replaces another in a compound

• Two elements combine to form a compound

What is the general formula for a single displacement reaction?

• AB + CD → AD + CB

• A + BC → AC + B

• A + B → AB

• AB → A + B

How can we predict if a single replacement reaction will occur?

• By checking the solubility of the products

• By using the periodic table

• By measuring the temperature change

• By using the activity series

Why is magnesium able to replace copper in copper(II) sulfate?

• Magnesium is more reactive than copper

• Copper and magnesium have the same reactivity

• Magnesium is less reactive than copper

• Copper is more reactive than magnesium

What happens to copper after magnesium replaces it in the reaction with copper(II) sulfate?

• It forms a new compound with sulfate

• It remains in the solution

• It ends up by itself

• It is released as a gas
