b) AgNO3 + NaCl --> AgCl + NaNO3
c) Pb(NO3)2 + 2NaCl --> PbCl2 + 2NaNO3
d) Zn + H2SO4 --> ZnSO4 + H2

Answer 1

what do u think it is ?

Answer 2

??????????????????

Answer 3

Since you aren't answering I'll show you what my answer is !
I chose d)
\[Zn _{s} +H _{2}SO _{4} \rightarrow ZnSO _{4} + H _{2}\]

Answer 4

there Zn is having 0 oxidation state in the reactant side and it goes to +2 oxidation. And H in reactants side has +1 oxidation and it goes to 0 oxidation state Cuz H2SO4 goes to H2 !

Answer 5

I hope u got it !!!!!! ;)
