Answer 1

(1) The molecular equation between Mg & HCl is Mg (s) + 2HCl (aq) MgCl₂ (aq) + H₂(g)

Total ionic equation is Mg (s) + 2H⁺ (aq) + 2Cl^- (aq) Mg²⁺ (aq) + 2Cl^- (aq) + H₂(g)

Net ionic Equation is : Mg (s) + 2H⁺ (aq) Mg²⁺ (aq) + H₂(g)

(2)

The molecular equation between Fe & HCl is 2 Fe(s) + 6 HCl(aq)   2 FeCl₃(aq) + 3 H₂(g)  

Total ionic equation is  2 Fe(s) + 6 H⁺ (aq) + 6Cl^- (aq)   2 Fe³⁺ (aq) + 6Cl^-(aq) + 3 H₂(g)  

Net ionic Equation is :2 Fe(s) + 6 H⁺ (aq)   2 Fe³⁺ (aq) + 3 H₂(g)

(3)

The molecular equation between Cu& HCl is Cu(s) + 2 HCl(aq) CuCl₂(aq) + H₂(g)
