Chemistry
1 answer:
Reil [10]2 years ago
8 0

Answer:

Double replacement or double decomposition

Explanation:

In the reaction below, a double replacement or double decomposition has occurred.

     

          2Na₃PO₄   +   3CaCl₂   →  6NaCl  +  Ca₃(PO₄)₂

This reaction occurs mainly between two ionic substances.

The reaction involves an actual exchange of partners to form new compounds. For example;

             AB  + CD →  AD + CB

One of the following conditions below serves as the driving force for double replacement reactions:

  • Formation of an insoluble compound or precipitate.
  • Formation of water or any other non-ionizing compound
  • Liberation of a gaseous product.

Find the no. Of electron involved in the electro deposition of 63.5g of cu from a solution of cuso4
sp2606 [1]
This is a redox reaction, meaning reduction-oxidation reaction. This represents the reaction in one side of the electrode in an electrolysis set-up. First, we find the oxidation number of Cu in CuSO4:

(ox. # of Cu)+ ox.# of S + 4(ox.# of oxygen) = 0
(ox. # of Cu) + (6) + 4(-2) = 0
ox. # of Cu = 2+

CuSO4 ---> Cu + SO42-
Cu2+ + SO42-  ---->  Cu + SO42-
Cu2+ -----> Cu + 2e-   (net ionic reaction)

The stoichiometric equation would be 2 electrons per mole Copper. Copper has a molar mass of <span>63.5 g/mol. Then, it would only need 2 electrons.
