Mg(s) + N₂(g) --> Mg₃N₂(s)
There is one Mg atom on the reactant side and three Mg atoms on the product side. So to balance the number of Mg on both side of the equation a coefficient 3 is placed before Mg on the reactant side. The number of N atoms are two on both side of the reaction. Therefore the balanced chemical equation is,
2Mg(s) + N₂(g) --> Mg₃N₂(s)

The electron configuration of Mg is 1s²2s²2p⁶3s² or [Ne]3s²
The electron configuration of Mg²⁺ is 1s²2s²2p⁶ or [Ne]
The electron configuration of Ne is 1s²2s²2p⁶
Ne he same electron configuration as a Mg²⁺ ion.

Mg has its valence electron in the 3s shell, but Mg²⁺ has no electron in the 3s shell, the valence electron in Mg²⁺is in the 2p orbital. The size of the 2 shell is smaller than the 3 shell. Hence, Mg²⁺ is smaller than Mg.
The balanced equation for the reaction between magnesium and nitrogen is 3Mg(s) + N2(g) -> Mg3N2(s). Neon has atoms with the same electron configuration as a magnesium ion. When an atom of a metal forms an ion, it loses electrons and has a smaller radius.
51. The balanced equation for the reaction between magnesium and nitrogen is:
3Mg(s) + N2(g) → Mg3N2(s)
52. The magnesium ion has the same electron configuration as a neon atom because both have the electron configuration of 2,8. Therefore, neon is the noble gas with atoms having the same electron configuration as a magnesium ion.
53. When an atom of a metal forms an ion, it loses one or more electrons to achieve a stable electron configuration. This results in a decrease in the size of the ion compared to the neutral atom. The loss of electrons reduces the repulsion between the remaining electrons, causing the ion to have a smaller radius.

The bottle left outside will have the same vapor pressure as the bottle inside the room because they both contain water.
The bottle left outside will have higher vapor pressure than the bottle from the room.
No change to either bottle.
A. High concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues
B. Low concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues
C. High concentration of oxygen in the blood; low concentration of carbon dioxide in the body tissues
D. Low concentration of oxygen in the blood; low concentration of carbon dioxide in the body tissues
Answer:
A. High concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues
Explanation:
Diffusion occurs from a region of higher concentration to a region of lower concentration. Diffusion occurs against a concentration gradient.
High concentration of oxygen in the blood causes oxygen to leave the blood and enter body tissues. High concentration of carbon dioxide in the body tissues causes carbon dioxide to leave body tissues and enter the blood.
Mg3 N2 how do I get my answer
The Lewis dot structure for Mg3N2 represents the ionic bonding between magnesium and nitrogen. Each magnesium atom donates its 2 valence electrons to nitrogen, as represented by zero dots around each Mg and eight around each N.
The student is asking about the Lewis dot structure of Mg3N2, which is commonly known as magnesium nitride. The Lewis dot structure is a graphical representation of the molecule that shows how the electrons are arranged among the atoms of the molecule.
To draw the Lewis dot structure for magnesium nitride, follow these steps:
This process represents the Ionic bonding in Mg3N2.
