Chemical chain Na-NaOH-Na2CO3-NaCL

1) To get the base you need: Na + OH = NaOH (metal ion + hydroxo group)
2) To get salt you need: You can add the acid with the base = salt + water, i.e. H2CO3 + NaOH = Na2CO3 + H2O
3) then we write out the salt and have to see what it will interact with in order to get another, well, i.e. salt + acid = new salt + new acid Na2CO3 + HCl = NaCl + H2CO3
