Is the reaction between sodium carbonate and sulphuric acid exothermic or endothermic?

The chemical equation you specify is neither chemically balanced, nor does it relate to the verbal description that precedes it.

I ibelieve you must mean:

Na2CO3 + H2SO4 → Na2SO4 + H2O + CO2

and as to whether it is exothermic or endothermic, I imagine that you are intended to deduce that by experimental means in a laboratory.

That was a spectacularly difficult question to find the answer to. He is quite correct, you do have the wrong equation written out. However, the answer to the question is exothermic. There is a negative delta H. I assume they showed you how to calculate the delta H? Or at least told you that heat is released from the reaction. Either of that information would allow you to conclude that it was an exothermic reaction.

Oh yea, it’s a mistake sorry lol. I did a titration and i need to tell in my write up whether it was exothermic or endothermic but i didn’t really look out if the flask became warm during titration so i’m trying to just find out because i didn’t even check for it. Thank you! :)
