Nitrogen is in group 5A of the Periodic Table and needs 3e to complete the octet rule, Mg is in group 2A of the periodic table and can only give out 2e to complete the octet rule, hence the formula Mg3N2

What are the ions and the correct formula for magnesium oxide?

the ions are 67 and one half since the molecular structuere


Magnesium oxide is an ionic compound represented by the formula unit?

The formula unit of magnesium oxide is MgO, composed of one magnesium ion (Mg2+) and one oxide ion (O2-). It forms a white solid with high melting and boiling points due to its ionic nature. Magnesium oxide is commonly used in agriculture, medicine, and various industrial applications.


What is the mass of 24.6 formula units of magnesium oxide?

To find the mass of 24.6 formula units of magnesium oxide, we first need to determine the molar mass of magnesium oxide. Magnesium has a molar mass of approximately 24.3 g/mol, and oxygen has a molar mass of approximately 16.0 g/mol. Therefore, the molar mass of magnesium oxide (MgO) is 24.3 + 16.0 = 40.3 g/mol. Next, we multiply the molar mass of MgO by the number of formula units (24.6) to find the total mass: 40.3 g/mol x 24.6 = 992.38 grams. Therefore, the mass of 24.6 formula units of magnesium oxide is approximately 992.38 grams.


What compound is magnesium and oxygen make?

Magnesium and oxygen combine to form magnesium oxide (MgO). Magnesium oxide is a white solid that occurs naturally as the mineral periclase. It is commonly used in various industrial applications, including as a refractory material and in the production of ceramics.


What is the number of formula units that are in 5.68 moles of magnesium oxide?

To find the number of formula units of magnesium oxide in 5.68 moles, you first need to determine the formula of magnesium oxide (MgO). Then use Avogadro's number (6.022 x 10^23) to convert moles to formula units. So, in 5.68 moles of MgO, there are approximately 3.43 x 10^24 formula units.
