Displacement Reactions starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Displacement Reactions.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A solution contains both AgNO3 and CuSO4. If a piece of zinc is added, which metals will be displaced?
A strip of metal X is placed in a solution of YSO4. After some time, metal Y is deposited and the solution contains XSO4. What can you conclude about the reactivity of X and Y?
A student adds a strip of zinc to a solution of copper(II) sulfate. What will be observed?
A student adds iron nails to a solution of copper(II) sulfate. After some time, the blue color of the solution fades and a reddish-brown deposit forms. What type of reaction is this?
Describe the role of the reactivity series in predicting displacement reactions.
Describe what happens when a piece of copper is placed in a solution of silver nitrate.
Explain why magnesium can displace zinc from zinc sulfate solution, but copper cannot.
Explain why silver does not react with dilute hydrochloric acid to produce hydrogen gas.
Explain why sodium cannot be displaced from sodium chloride by any other metal.
Write a balanced chemical equation for the displacement reaction between iron and copper(II) sulfate.
Write the balanced chemical equation for the reaction between chlorine gas and potassium iodide solution.
