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 11
A solution contains both AgNO3 and CuSO4. If a piece of copper is added, which metal will be deposited first?
A solution contains both FeSO4 and CuSO4. If a zinc strip is added, which metals will be displaced?
A strip of zinc is placed in a solution of copper(II) sulfate. After some time, the blue color of the solution fades and a reddish-brown deposit forms. Explain the changes observed.
A student adds a piece of magnesium to a solution of lead(II) nitrate. Predict the products and write the balanced equation.
