Explanation / Answer

a1) 2HCl(aq) + Co(s) ----> CoCl2(aq) + H2(g) molecular equation

a2) 2H+(aq) + 2Cl-(aq) + Co (s) -----> Co+2(aq) + 2Cl-(aq) + H2(g) ionic equation

a3) 2H+(aq) + Co(s)----> Co+2(aq) + H2(g) net ionic equation

b1) 2HCl(aq) + 2Cs(s)----> 2CsCl(aq) + H2(g)

b2) 2H+(aq) + 2Cl-(aq) + 2Cs(s)----> 2Cs+(aq) + 2Cl-(aq) + H2(g)

b3) 2H+(aq) +2Cs(s)----> 2Cs+(aq) + H2(g)

c1) 2HCl(aq) + Zn(s) ----> ZnCl2(aq) + H2(g)

c2) 2H+(aq) + 2Cl-(aq) + Zn(s) ----> Zn+2(aq) + 2Cl-(aq) + H2(g)

c3) 2H+(aq) + Zn(s) ----> Zn+2(aq) + H2(g)
