Homework Answers
the reactants are Zn and H2SO4 products are ZnSO4 and
H2
the balanced equation is as follows
Zn (s) + H2SO4(aq) --------------------> ZnSO4(aq) + H2(g)
total ionic equation is as follows
Zn(s) + 2 H+(aq) + SO42-(aq) ----------------------->Zn2+(aq) + SO42-(aq) + H2(g)
net ionic equation is as follows
Zn(s) + 2 H+(aq) --------------------------> Zn2+(aq) + H2(g)
oxidised => Zn
reduced => Hydrogen
more reactive = Zn
less reactive = Hydrogen
