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?
