hi

zinc reacts with HCl according to the eq

Zn + 2HCl ------> ZnCl2 + H2 , delta H= -150 kj

* IF SULPHURIC ACID IS USED INSTEAD HCl ..jow many moles of sulphuric acid react with excess amount of zinc so the change in heat content is -150 kj

You have to try by yourself first.

Besides, it looks like a homework question to me, and this is not a forum for HW.

Write net ionic reaction equation, it should be obvious then. But you seem to be on the right track.
