A mole or fraction of a mole represents a specific <span>number of atoms or molecules. The correct option among all the options that are given in the question is the first option or option "a". The other choices in the question are incorrect. I hope that the answer has actually come to your great help.</span>
<span> Na2CO3 + 2HCl = CO2 + H2O + 2NaCl
this is the double displacement reaction
</span><span>2 Na(+) + CO3(-2) + 2H(+) + 2Cl(-) ------> 2Na(+) + 2 Cl(-) + H2O + CO2
</span>2Na+ and 2Cl- are the spectator ions as they appear on the both sides of equation :
so the net ionic equation can be written as :
CO3(-2) + 2H(+) -------------> <span>H2O + CO2</span>
