Explanation:
Detailed explanation-1: -The balanced Eqn is : Zn+2HCl→ZnCl2+H2. Was this answer helpful?
Detailed explanation-2: -Zinc metal reacts with hydrochloric acid according to the balanced equation: Zn(s) + 2 HCl(aq)¡ZnCl2(aq) + H2( g) When 0.103 g of Zn(s) is combined with enough HCl to make 50.0 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.5 °C to 23.7 °C.
Detailed explanation-3: -This is an unbalanced equation.
Detailed explanation-4: -Zinc displaces hydrogen from hydrochloric acid so, its a displacement reaction.
