Question:

A 0.879g of a sample a CaCl₂*H₂0/K₂C₂O₂ solid salt mixture is dissolved in 150mL of deionized water. A precipitate forms which is then filtered and dried. The mass of this precipitate is 0.284g. The limiting reagent in the salt mixture was later determined to be CaCl₂*2H₂0

(a) write the molecular form of the equation for the reaction.

(b) Write the net ionic equation for the reaction.
