Question

Consider the half reactions below for a chemical reaction.

Answer 1

Answer:

IT's d on edge

Explanation:

Answer 2

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
