Single Displacement Reactions

The video tutorial explains the type of reaction between zinc and copper sulfate, identifying it as a single displacement reaction. It describes how zinc displaces copper due to its higher reactivity, forming zinc sulfate. The video also discusses the activity series of metals, which helps predict such reactions, and provides an overview of common chemical reaction types.

What type of reaction occurs when zinc reacts with copper sulfate?

• Decomposition reaction

• Double displacement reaction

• Single displacement reaction

• Synthesis reaction

In a single displacement reaction, what happens to the metal that is displaced?

• It forms a new compound

• It is released as a free element

• It decomposes into simpler substances

• It remains bonded to the original compound

What happens to copper in the reaction between zinc and copper sulfate?

• It forms a new compound with zinc

• It remains in the solution

• It is released as a free element

• It decomposes into simpler substances

Which of the following best describes the general formula for a single displacement reaction?

• A + BC → AC + B

• AB → A + B

• AB + CD → AD + CB

• A + B → AB

How can you determine if a single displacement reaction will occur?

• By observing the color change

• By checking the solubility of the compounds

• By comparing the reactivity of the metals involved

• By measuring the temperature change

What is the role of the Activity series in predicting single displacement reactions?

• It lists metals in order of increasing atomic mass

• It ranks metals based on their reactivity

• It shows the solubility of different metals

• It provides the melting points of metals

Why is zinc able to displace copper in the reaction with copper sulfate?

• Zinc has a higher atomic number than copper

• Zinc is denser than copper

• Zinc is more reactive than copper

• Zinc is less reactive than copper

Which metal is more reactive according to the Activity series: zinc or copper?

• Neither is reactive

• Copper

• Both are equally reactive

• Zinc
