Answer:
vigorous reaction will occur giving rise of heat as it is an exothermic reaction. If heat is applied then it should be more vigorous.
Reaction is as follows:
Mg(s) + HCl(aq) --> MgCl2(aq) + H2(g)
Magnesium reacts easily withHCl to produce H2 gas and magnesium ions, Mg2+, and heat. The reaction isexothermic, so it heats up quickly.
Mg(s) + HCl(aq) --> MgCl2(aq) + H2(g)
The net ionic equation :
Mg(s) + 2H+ --> Mg2+ + H2(g)
If water is removed from the solution then white crystals of Mgcl2 is obtained.
