Why does zinc react with hydrochloric acid? – …
WebApr 15, 2024 · The reaction of zinc and hydrochloric acid is specifically a combustion reaction, which is also called an exothermic reaction. Exothermic reactions always involve oxygen, and they always generate heat. Reactions that generate heat and light are called burning reactions. WebAnswer (1 of 2): I think most, if not all, reactions that occur ‘spontaneously’ will be exothermic. Some require ‘activation energy’ to get started, like the burning of wood or paper. Chemical energy is converted into heat, in correspondence with the 2nd law of thermodynamics. Ultimately, all ene... gfebs who performs strategic planning
Why copper does not react with hydrochloric acid - Byju
WebWhat does Zn HCl do? 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. WebSolution. in case of copper Copper is below hydrogen in the reactivity series. This means that copper is less reactive than hydrogen and hence cannot displace it from the acidic solution. so, this is the reason copper does not react with hydrochloric acid. WebMar 30, 2024 · Metals to the left of hydrogen in the electrochemical series react with hydrochloric acid. These elements include lithium, potassium, calcium, sodium, … gfebs work notification
