Question

Zinc granules on reaction with hydro chloric acid gives zinc chloride and hydrogen gas.? i) What type of heat change is observed in this reaction and write its name? ii) Write word equation for this reaction(if anyone spams u will be reported)​

Zinc chloride and hydrogen gas are formed, when zinc granules are treated with hydrochloric acid. Similarly, hydrogen gas and zinc nitrate are formed when zinc granules are treated with nitric acid.

1. 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.
2. Negative Enthalpy
