Question

Which represents the balanced double displacement reaction between Sodium Chloride (Na+Cl-) and Copper Sulfate (Cu2+(SO4)2-) ?

NaCl + Cu(SO4) --> Na2(SO4) + CuCl2

NaCl + Cu(SO4) --> Na(SO4) + CuCl

2NaCl + Cu(SO4) --> Na2(SO4) + CuCl2

NaCl + Cu(SO4) --> Cl(SO4) + NaCu

Answer 1

The correct answer is C. I just took the test. Good Luck! :)

Step-by-step explanation:

Answer 2

The balanced double displacement reaction is as follows.

`2NaCl+CuSO_(4)\rightarrow Na_(2)SO_(4)+CuCl_(2)`

Step-by-step explanation:

The given reactant has sodium,chloride and copper sulfate ions.

In the double displacement reaction, two ionic compounds exchange their cations.

Sulphate and chloride ions are cations these are exchanged sodium and copper elements.

Hence, the balanced double exchange reaction is as follows.

`2NaCl+CuSO_(4)\rightarrow Na_(2)SO_(4)+CuCl_(2)`
