Explanation / Answer

Part C:
write the complete ionic equation for the reaction
HCHO2(aq) + NaOH(aq) -->

Since formic acid is a weak acid, it won't dissociate completely into cations and anions like strong acids.
Therefore, the complete ionic equation is:
HCHO2(aq) + Na+(aq) + OH-(aq) ---> H2O(l) + CHO2-(aq).

Part D:
Write the balanced net ionic equation:

Then cancel the spectator ion or ions which are common on both side in the complete ionic equation,
we can get:

HCHO2(aq) + OH-(aq) ---> H2O(l) + CHO2-(aq).

Part E:
Write the balanced complete ionic equation for the reaction:
HC2H3O2(aq) + LiOH --->

Here, also we have acitic acid (HC2H3O2) a weak acid. Therefore, the complete ionic equation is:
HC2H3O2(aq) + Li+ (aq) + OH-(aq) ---> H2O(l) + C2H3O2-(aq)

Part F:
Net Ionic Equation is:
HC2H3O2(aq) + OH-(aq) ---> H2O(l) + C2H3O2-(aq)
