Please tell me the Net Iconic Equations for these Chemical Reactionsf.Zn(s)+2HCl(aq)=ZnCl2(aq)+H2, g.Zn(s)+H2SO4(aq)=ZnSo4(aq)+H2g, h.Cu2+4NH3(aq)=Cu(NH3)4(aq)
Explanation / Answer
f.) Zn(s) + HCl(aq) --> H2(g) + ZnCl2 The balanced equation can be found from half cell reactions: Zn(0) --> Zn(2+) + 2e(-) 2H(+) + 2e(-) --> H2 =================== Zn(0) + 2H(+) --> Zn(2+) + H2 Note that this is also the ionic equation. The full equation is like this: Zn(0) + 2HCl --> ZnCl2 + H2 g)Zn(s) + 2H+(aq) ---> Zn^2+(aq) + H2(g). h) Cu(NH3)4^+2(aq) + CO3^-2 CuCO3(s) + 4NH3
