We combine the two equations, like we would any mathematical system of equations. After addition of the two equations, we get:
Mg + 2H⁺(aq) + 2e⁻ → Mg⁺²(aq) + H₂(g) + 2e⁻
Cancelling like terms from both sides
Mg + 2H⁺(aq) → Mg⁺²(aq) + H₂(g)
Water, ALSO if you cant figure out the answer looking up on g00gl3e
Because they are the means by which energy needed for photosynthesis is transported into the plant in form of light ernegy
