Is the reaction between zinc and hydrochloric acid exothermic?
Yes there is bond formation, hence exothermic, negative enthalpy change in rate of reactive (-ve delta H), energy is released.
Acid metal reactions usually produce a salt, in this case, zinc chloride and hydrogen gas. After adding magnesium ribbon/strips to HCl, you will realise that the test tube is warm. That’s due to heat energy which is being released from the reaction.
