Write a molecular form of the equation for the reation CaCl2*2H2O/K2C2O4*H2O

Answer 1

It is very difficult without the medium.

Calcium acetate is very insoluble, however it is hygroscopic, in a non-aquesous envirnoment, it gains water to form Ca(C2O4).H20.

In a water solution, it probably has the forms CaC2O4.xH2O

potassium chloride in an aqueous solution is ions (aq).

So without more information on the reaction environment, this is about all you can get.
