MgO, since both have a charge of 2 therefore they cancel each other out.
Magnesium Oxide
Yes. Magnesium oxide will react with water to form magnesium hydroxide.
A compound / element created by a chemical reaction. Example: Magnesium + Oxygen -> Magnesium Oxide The Magnesium Oxide would be the Product.
Magnesium oxide is formed when magnesium metal reacts with oxygen. It is an oxide of magnesium. Magnesium is the metal, and magnesium oxide is the resulting compound formed when magnesium reacts with oxygen.

When water is added to magnesium oxide, magnesium hydroxide is formed. The pH of this solution would be basic, usually around 9-10, due to the presence of hydroxide ions.
== == MgO That would be Magnesium rust. It makes Magnesium off color and cloudy.
That would be Magnesium Oxide (since a single element cannot decompose) which decomposes into Magnesium and Oxygen. Magnesium Oxide --> Magnesium + Oxygen or the balanced chem. equation: 2MgO --> 2Mg + 02
When magnesium reacts with oxygen to form magnesium oxide, the ratio of magnesium to oxygen is fixed according to the chemical equation (2Mg + O2 -> 2MgO). This means that the amount of magnesium oxide that can be formed is limited by the amount of oxygen available, not by the amount of magnesium present. So, increasing the amount of magnesium does not lead to a corresponding increase in magnesium oxide produced.
The formula of the magnesium oxide formed would not change at all if impure magnesium was used, but less of the magnesium oxide would be formed than if the same amount of pure magnesium had been used. Depending on the chemical nature of the impurities, other products might be formed, or the impurity might simply remain as a contaminant of the magnesium oxide.
Did you want the formula? If so it is MgO.
Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.
