When zinc is added to copper sulfate solution, zinc sulfate and copper are produced. Which are the products of the reaction?
Zinc and copper sulfate
Copper and zinc sulfate
copper
sulfate
When zinc is added to copper sulfate solution, zinc sulfate and copper are produced. What is this reaction known as?
Neutralisation
Oxidation
Displacement
Thermal decomposition
When zinc is added to copper sulfate solution, zinc sulfate and copper are produced. Why is the copper displaced?
Because zinc is more reactive than copper
Because the copper is more reactive than zinc
Because they are equal in their reactivity
Copper is unreactive.
