One the the simplest formulas for students come know and also retain throughout tests or exams is the chemical Formula of Magnesium Oxide. Prior to we obtain into the formula, let"s have actually a look at the MgO compound surname itself. Magnesium oxide, often known together magnesia, is a naturally arising alkaline planet metal oxide the is mainly produced by calcining particular minerals. At high temperatures, that is a solid that is both physically and chemically stable. As a result, it"s commonly employed in refractory materials.

You are watching: What is the correct formula for magnesium oxide

MgO compound Name

Magnesium oxide is created up of the ion Mg2+ and also O2-, which are joined by an ionic connection. However, based upon the valency, we can conclude that the net charge in the molecules is zero and also balanced, v one magnesium and one oxygen atom. As a result, the chemistry formula for Magnesium Oxide is MgO.

Properties the Magnesium Oxide Formula

Molecular formula that magnesium oxide- MgO

Molar mass of magnesium oxygen symbol- 40.3044 g/mol

Density that magnesium oxygen formula- 3.58 g/cm3

Melting Point- 714 °C

Boiling Point- 1090°C

Experiment to show Burning that Magnesium Ribbon Equation

When a item of magnesium ribbon is ignited, that produces light and heat.


This is a simple demonstration that describes the magnesium oxide symbol and the ide of an exothermic procedure and one that produces irradiate energy.

Materials Required:

6-8 cm magnesium ribbon sanded to remove oxide coating

Bunsen burner, charcoal grill lighter or similar



Adjust the flame to light blue ~ lighting the burner. Location the other end of the magnesium ribbon in the flame while holding one end with tongs. Hold the flaming ribbon in ~ arm"s size is recommended. Magnesium burns brightly and also generates a lot of heat.

2Mg + O2 → 2MgO (magnesium ribbon formula)

Magnesium oxidation or burning in air has actually long to be employed in photography and other optical chemicals reactions as a resource of shining light. The power released in this burning is due to the reaction the magnesium through oxygen in the air, as shown in magnesium oxide balanced equation:

Magnesium oxide has actually a warm of formation of -601.83 kJ/mol. As soon as magnesium burns, around 10% the the energy is convert to light, a figure that is unmatched amongst known energy transformations employed in the production of light.


The light from the burn magnesium ribbon is strong enough come inflict momentary blindness. Avoid gazing straight at the resource of light. As soon as magnesium is melted in the air, the produces a lot of heat, which deserve to inflict burns and also start a fire in flammable objects. A dry-powder extinguisher need to be used since a carbon dioxide fire extinguisher will not extinguish burning magnesium.

Procedure for Balancing a Magnesium Oxide Equation:

To recognize the stages needed in balancing a chemical equation, consider the chemical interaction between magnesium and also oxygen.

Let"s start by composing the reaction"s native equation.

Magnesium + Oxygen → Magnesium oxide

Step 2: compose the chemical equation because that the magnesium-oxygen reaction.

Mg + O2 → MgO

Step 3: counting how plenty of times each element appears on both the LHS and RHS of this equation.

Mg + O2 → MgO

This is one unbalanced magnesium oxide equation.

On every side that the equation, there room two oxygen atoms, but one magnesium atom on the reactants" side and two ~ above the product"s side. As a result, on the left-hand side, main point the magnesium atom through two.

The well balanced equation is

2Mg + O2 → 2MgO

The number of atoms in every reactant facet equals the variety of atoms in every product element.

Using the arrow to write particular conditions The reaction takes location in the existence of heat." once magnesium is heated, the reacts through oxygen in the waiting to create magnesium oxide.

Magnesium oxide (MgO), or magnesia, is a white hygroscopic heavy mineral the occurs normally as periclase and is a source of magnesium. MgO is prized as a refractory product that is physically and chemically secure at high temperatures.
