2 Fe (s) + 3 H 2SO 4 (aq) → Fe 2(SO 4) 3 (s) + 3 H 2 (g). This is an oxidation-reduction (redox) reaction: 6 H I + 6 e - → 6 H 0 (reduction).
The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
The balanced equation for Na and H2so4 is Na+ H2SO4 = na2so4 + h2 it is self balanced The balanced equation for Na and H2so4 is Na+ H2SO4 = na2so4 + h2 it is self balanced ---- The answer above, H2SO4 is sulfuric acid. The formula for hydrochloricacid is HCl. Therefore: the equation is: Na + HCl --> NaCl + H2 The balanced equation would be (by my working): 2Na + 2HCl --> 2NaCl + H2 However, this is just how I would work it out and may again be wrong.

H2SO4 + Fe = FeSO4 + H2
The reaction is:Mg + H2SO4 = MgSO4 + H2
2H2S+3O2 --> 2H2O+2SO2there's your balanced chemical formula.
Mg + H2SO4 ---> MgSO4 + H2
Ba + H2SO4 ---> BaSO4 + H2
Ca + H2SO4 --> CaSO4 + H2
Mg + H2SO4 = MgSO4 + H2
Mg+H2SO4---> MgSO4+H2 is already a properly balanced equation .Magnesium (Mg) + sulphuric acid (H2SO4) will give MgH2SO4 (a corresponding metallic salt) + hydrogen gas.
In the example of an alkali metal (valence +1) with sulfuric acid: 2Na + H2SO4 --> Na2SO4 + H2 In the example of a Group 2 metal (valence +2) with sulfuric acid: Ca + H2SO4 --> CaSO4 + H2
The sought equation is H2SO4 + Zn(OH)2 => ZnSO4 + 2 H2O.
