In a lab about the activity series, a solution of copper(II)chloride is placed in a test tube with zinc metal. If zinc is higher
Tcecarenko [31]

Answer:

Option D, Zinc is higher on the activity series because there is clear evidence of a reaction.

Explanation:

It is very clear that a metal which is higher in activity will replace a metal having lower activity.  

Since, Zinc has higher activity than copper, it is very sure that it in a copper chloride solution it will replace copper and produce zinc chloride solution leaving behind copper as residue.  

Residues of copper is a clear evidence of reaction  

The chemical equation for this reaction would be -

CuCl_2 + 2Zn^+ -----> 2ZnCl + Cu^{2+}

  • In the lake, these nutrients promotes the growth of plants like algae.
  • The excessive growth of algae in the lake disturbs he ecological balance of the lake and causes a dearth of oxygen in it. This phenomenon is said to be called Eutrophication.
  • The reduction in the level of oxygen in the lake causes the animals, like fishes, in it to gradually die.
