Upper M g (s) plus 2 upper H right arrow upper M g (a q) plus upper H subscript 2 (g).
Mg + 2H⁺ → Mg²⁺ + H₂
Explanation:
The net ionic equation is the sum of the oxidation half reactions.
The half-reactions are:
Mg → Mg²⁺ + 2e⁻ Oxidation half reaction
2H⁺ + 2e⁻ → H₂ reduction half reaction
Combining the reactions gives:
Mg + 2H⁺ + 2e⁻ → H₂ + Mg²⁺ + 2e⁻
Since the electrons are balanced, they cancel out of the equation,
This leaves behind;
Mg + 2H⁺ → Mg²⁺ + H₂

Explanation:
Nh4OH + HCL ---> NH4Cl + H3O
so ph decreases as H3O increases
and OH also decreases
