What is the overall equation for this chemical reaction?

1 answer:

3 0

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)

Answer:

Correc option: $Br^- \, , Kr$

Explanation:

size of atom : it says somthing about how many shell present in a particular atom or ion and it can also be evaluated on the basis of radius of atom.

Br^- and Kr has highest number of shell as compared to other group of species .

Na ,S , Mg ,P all are from 3rd period but Kr and Br^- in the 4th period so size of species of this group will more,

Size increases on increasring the shell number
