Na2CO3 + HCl → NaCl + NaHCO3 NaHCO3 + HCl → NaCl + H2O + CO2 The conjugate acid produced from the first equation is so weak that it can accept another proton to form NaCl creating two concentrations of where the [OH]=[H+]
I think I kind of get that
But then how this gets the moles of ethanediocacid I don't know
For questions that ask for equations, particularly fragmentation equations, I always end up drawing out the compound (instead of writing CH3CH2CH2 etc.) will I lose marks?????????
The arrow from the OH bond is where the double dond would be. In other compunds there could be multiple places the double could go which leads to isomers

Sometimes they specifically want a displayed formula as well so it's safe to do so. Unless they speficially ask for the structural formula then you should be ay-okay

they are never clear what they want, whether that be the structural formula or displayed, so i think both are accepted
