Atoms want to be stable, that's essentially their only purpose in life.
How, then, does an atom become stable? Well, they either lose all their electrons, or gain electrons so they have 8 (Except for a couple atoms like helium, they just need two electrons).
Magnesium has two valence electrons, and obviously it seems a bit unconventional to try and gain 6 electrons when you could just lose 2. Why spend more effort?
Because it loses 2 electrons, Mg will become (It has lost 2 electrons, and therefore becomes positive)
Good luck! If you have any questions, just ask :))

Answer:
Molecule
Explanation:
when two or more than two non-metal elements are combined then it form Molecule.
Mass of Aluminum = 157.5 g
<h3>Further explanation</h3>
Given
17.5 g of Hydrogen
Required
Mass of Aluminum
Solution
Reaction
2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
mol Hydrogen :
= mass : molar mass
= 17.5 g : 2 g/mol
= 8.75
From the equation, mol Al :
= 2/3 x mol H₂
= 2/3 x 8.75
= 5.83
Mass Al :
= 5.83 x 27 g/mol
= 157.5 g
The solution with a pH of 3 in 100 times more acetic than the solution with a pH of 5. This is because the lower the pH goes, 10x the pH decreases for each pH "level." For example, a solution with a pH of 4 is 10x more acetic than pH of 5.
