Any help is appreciated.

You may note that in the first reaction, there is 1 mole of NaOH for each H2CO3 and in the second, there are 2 moles of NaOH. The first mole is sufficient to convert the carbonic acid to the bicarbonate. The second mole is needed to covert the bicarbonate to the carbonate.

this is the answer: 2 NaOH + H2CO3 => Na2CO3 + 2 H2O

acid base equilibriums
the second one has 2 eq. of OH(-) so it can do 2 rxns
ignoring spectator ion Na(+)
OH(-) + H2CO3 <==> HCO3(-) + HOH
where OH(-) deprotonates H2CO3
then
2OH(-) +H2CO3<==>CO3(2-) + 2H2O
is actually
OH(-) + H2CO3 <==> HCO3(-) + HOH
and
OH(-) + HCO3(-) <==> HOH + CO3(2-)
