Examples: magnesium oxide (MgO), magnesium chloride (MgCl2).
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
Magnesium bromide IS a molecule, or more correctly, it is a formula unit. So, magnesium bromide doesn't HAVE any molecules. One formula unit of magnesium bromide has THREE ATOMS, and they are 1 magnesium atom and 2 bromine atoms (MgBr2).
Magnesium sulfate molecules doesn't freeze.
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.
The chemical equation is:2 Mg + O2 = 2 MgO
Magnesium sulfite has 6 water molecules.
No, only it's oxidation state is 2. Don't confuse it.
Magnesium hydroxide Oxides are in general Bronsted bases, and very strong ones at that. Bronsted bases like to pick up hydrogens, and so in the presence of water O2- will pick up a hydrogen from water: O2- + H2O ---> 2 OH- In this particular case since magnesium hydroxide is an insoluble compound you get: MgO + H2O ---> Mg(OH)2
In magnesium sulfate heptahydrate, the term "heptahydrate" means there are seven water molecules associated with each formula unit of magnesium sulfate. So, in one formula unit of magnesium sulfate heptahydrate, there are 7 water molecules.
The answer is 9,3945.1023 molecules.
I believe it is Magnesium Oxide. The 2 should be subscript, denoting the presence of two atoms of magnesium. This is because magnesium has a charge of -1, versus oxygen's typical charge of +2. Two atoms of magnesium balances the compound. No, magnesium oxide would be MgO - the magnesium has an oxidation number (or charge) of +2, compared with -2 for oxygen, so one of each is needed to balance out the molecule. I don't think Mg2O exists.
[well you would show the 2 diffrent particle (oxygen and magnesium) with 1 magnesium particle and 2 oxygen ones attached to it . this is known as MgO2] i believe it is MgO as the electron number is too big to support 2 molecules of oxygen
