According to Arrhenius theory of acid and base, Acids are those substances which when dissolved in water produces protons, while, Bases are those substances which when dissolved in water produces Hydroxyl Ions.
Example of Arrhenius Bases:
NaOH ₍s₎ → Na⁺ ₍aq₎ + ⁻OH ₍aq₎
LiOH ₍s₎ → Li⁺ ₍aq₎ + ⁻OH ₍aq₎
Result:
The only negative ion produced in water when Arrhenius Base is dissolved is ⁻OH (Hydroxyl Ion).
1.4mL
Explanation:
Given parameters:
Mass of object = 3.5g
density = 2.5g/mL
Unknown:
Volume of the object = ?
Solution:
Density is the mass per unit volume of a body. It is an intensive property that is the same for the same substances.
Density = 
since the volume is unknown; we make it the subject of the formula;
Volume = 
Volume = 
Volume of the object = 1.4mL

Answer:
The answer to your question is Mg loses its valence electrons and acquire a positive charge (Mg⁺²).
Explanation:
Valence electrons are important for an element to attach to another one, metals lose these electrons while nonmetals gain electrons to complete the octet rule.
Magnesium is a metal that loses these electrons so when it becomes an ion Magnesium will have a positive charge Mg⁺².
Answer:
Sulfur is a non mental, because it is consistent with the 3 physical properties listed for nonmetals
