they all caceled out when i did it.
thanks.

Mg + 2H+ --> Mg2+ + H2
Only the chloride ions are spectators. The magnesium and hydrogen do not cancel out because they're not the same species on both sides of the equation. Magnesium is atomic and solid on one side, and ionic and aqueous on the other. Hydrogen is ionic and aqueous on one side, and diatomic and gaseous on the other. Chloride, though, is a solvated ion on both sides.

The ionic equation will be like this: Pb2+ 2NO3? + 2Na+ SO4-2 --------> 2Na+ + 2NO3? + PbSO4 (s) right here PbSO4 is sweet, so its not written in words of its ions. yet NaNO3 is dissolved interior the electrolyte so its written in type of its ions. the web ionic reaction may nicely be written as follows: Pb2+(aq) + SO4-2(aq) -----> PbSO4(s) right here we've written purely that area which became previously in ionic type contained in the electrolyte yet after the reaction it has became into an outstanding. Na and NO3 ions are nevertheless modern-day interior the answer even after the reaction, so we choose not write them in a information superhighway ionic reaction..

Mg + 2(H+) --> (Mg2+) + H2
Cloride cancels out due to the fact that it does not change its behavior. the Mg goes from atomic to ionic and the H2 goes from aqueous to gaseous. Hope that helps!

they will give you Mg + 2H(+1)=>Mg(+2) +H2
because Mg solid they will stay Mg(0) cantcancel Mg(+2)
and Hydrogen on right hand side is neutral ( diatomic) can not cancel with ion
good luck
