Answer:
The metal zinc readily reacts with hydrochloric acid to produce hydrogen gas (H2) and zinc chloride (ZnCl2). Every chemical reaction either produces or absorbs heat. In chemistry this effect is described as the reaction enthalpy. The zinc reaction produces the heat and hence has the negative enthalpy.
