Write the MOLECULAR EQUATION between iron and copper (II) sulfate.

Aleksandr-060686 [28]

Answer : The balanced molecular equation will be:

$Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)$

Explanation :

Molecular equation : It is a balanced chemical reaction in which the ionic compounds are expressed as the molecules instead of component ions.

According to the question, when iron react with copper (II) sulfate then it react to give iron (II) sulfate and copper as a product. In this reaction, iron is more reactive metal than the copper metal. So, it can easily displace copper metal form the solution.

The balanced molecular equation will be:

$Fe(s)+CuSO_4(aq)\rightarrow FeSO_4(aq)+Cu(s)$

If you dive out just past the continental slope and look at the living things on the ocean floor which zone are you exploring

mamaluj [8]

Lies just beyond the continental slope is the open ocean zone and it has three subzones namely the epipelagic(sunlit zone), mesopelagic(disphotic zone) and bathypelagic zones(aphotic zone). The oceanic zone covers 65% of the ocean's water and where different types of terrains can be found. From deep trenches, deep sea volcanoes and basins. A variety of sea creatures can also be found on each subzone.
