Final answer:
The chemical formula Na_2OOCCOO does not correspond to a standard compound, but it seems to indicate sodium oxalate, which has the formula Na2C2O4. The dissociation equation for sodium oxalate in water is Na2C2O4 (s) → 2 Na+ (aq) + C2O42- (aq), yielding two sodium ions and one oxalate ion.
Step-by-step explanation:
The dissociation equation for a compound involves breaking it down into its constituent ions. Using the provided examples, we can see how different ionic compounds dissociate in water. For instance, sodium chloride (NaCl) dissociates into sodium ions (Na+) and chloride ions (Cl-).
However, the compound Na2OOCCOO is not a standard chemical formula, and it seems there might be some confusion or typo. It could be an attempt to express a compound such as sodium oxalate, which has the formula Na2C2O4. The dissociation of sodium oxalate would be represented as:
Na2C2O4 (s) → 2 Na+ (aq) + C2O42- (aq)
In this dissociation equation, the sodium oxalate compound dissociates into two sodium ions and one oxalate ion in aqueous solution.
