I was looking at 2010 sample answers and the reaction for question 28 was confusing, there was no Na2CO3 or HCL in the equation? Is this the wrong equation or the right one? If it's right please explain it for me.

They used an ionic equation (ignore spectator ions).

The equation is:

HCl +Na2CO3 -> H20 + CO2 +NaCl

(That's not balanced though.)
