1)Write the BALANCED equation for the reaction
with CORRECT state symbols:
Mg(s) +2HCl(aq)---------->MgCl2(aq) +H2(g)
2)Now rewrite the equation replacing aqueous substances
as they would appear in solution( ie)as ions.Leave
everything else as is in the standard state.
Mg(s) + 2H+ (aq) + 2Cl-(aq)---->Mg2+(aq) +2Cl-(aq) +H2(g)
3)Now cancel ions common to both sides ,that is,spectator
ions.
Cancel the 2Cl-(aq) on each side.
4)Rewrite the equation without what you have canceled.
Mg(s) + 2H+(aq)------>Mg2+(aq) + H2(g).
Good Luck.
The reaction is: Na2CO3 + 2HCl = 2NaCl + CO2 + H2O The net ionic is CO32- + 2 H+ = H2O + CO2
Mg (s) + 2H2O(g) -> Mg(OH)2(aq) + H2(g)

The chemical equation is:Mg+ + 2 OH- = Mg(OH)2(s)
H+ + oh- ---> h2o
The net ionic equation is Zn + 2H+ --> Zn2+ + H2
The net ionic equation for the reaction of 1HF and MGCl2, with 2HF and NHbR, would be approximately 2GCF. This can fluctuate a bit, but will wholly depend on if the NHbR changes at all.
mg + CuCl2 + MgCl2 + Cu Mg + Cu^+2 = Mg^+2 + Cu
The reaction is: Na2CO3 + 2HCl = 2NaCl + CO2 + H2O The net ionic is CO32- + 2 H+ = H2O + CO2
Mg (s) + 2H2O(g) -> Mg(OH)2(aq) + H2(g)
