Magnesium

Pure ionic in Mg(OH)2 = Mg2+ and 2 OH-

The chemical formula for magnesium phosphate is Mg3(PO4)2. This mineral is very important and keeps the human body working properly.

The electron configuration of caesium is: [Xe]6s1.

Yes, milk of magnesia is a heterogeneous mixture. It contains insoluble solid particles of magnesium hydroxide suspended in a liquid, resulting in a mixture with visibly different components that do not fully dissolve.

The molar mass of Magnesium Oxide (MgO) is 40.3044 grams per mole. This means in chemistry terms that there is 1 gram per 6.02 x 1023 molecules of Magnesium Oxide (the ratio for grams to molecules would be 1:6.02 x 1023)

The point of a Grignard reaction is to form a new carbon-carbon bond. To do this, you need a reagent with a relatively negative carbon. This is unusual, since carbon has a fairly low electronegativity - 2.5 - and thus generally has a partial positive charge, rather than a negative one. However, magnesium has an even lower electronegativity, namely, 1.2. The large difference in electronegativity between carbon and magnesium, 1.3, creates a very polar covalent bond between the two when they are bonded to each other. Thus, magnesium is necessary in the Grignard reagent because it creates the partial negative charge on the carbon to which it is bound, allowing the reaction to happen.

Mg(s) | Mg2+(aq) Al3+(aq) | Al(s) and that is how a pro does it

There are over 60 minerals in which magnesium is found. Brucite, carnallite, dolomite, magnesite, olivine and talc are the important commercial ones. Note that magnesium can also be produced from magnesium-containing compounds recovered from brines, sea water and from wells. Links are provided to the relevant Wikipedia articles.

Magnesium = Mg+2

Oxygen = O-2

(Mg+2)+(O-2) = MgO = Magnesium Oxide

so the formula for oxygen + magnesium - oxygen + magnesium oxide

First, the sea water is collected in large basins and heated to evaporate some of the water. This yields a concentrated solution of water and various salts which are mixed with calcium hydroxide (lime) to yield a magnesium hydroxide precipitate. The precipitate is then reacted with hydrochloric acid to yield magnesium chloride. This is then separated into molten magnesium metal and chlorine gas ions through the electrolysis process. The chlorine is reacted with hydrogen to yield hydrochloric acid to be recycled, while the molten magnesium is then cast into ingots.

soluble
Soluble in water.

Zn + 2HCl --- ZnCl2 + H2 Mg + 2HCl --- MgCl2 + H2

Answer will be (mg/L) as CaCO3

units of ppm are the same as mg/L.

Hardness = 2.5(mg Ca/L) + 4.1(mg Mg/L)

In this case: 2.5x78.4 + 4.1x104.5 = 624.45 mg/L

positive ion - magnesium(cation)

negative ion-chloride (anion)

P = CqB^2

Magnesium has two outer shell electrons which are loosely held. This is not a stable configuration. As a result magnesium will lose those two electrons, making the electron shell below that, which has 8 electrons, the new outer shell. An electron shel with 8 electrons is stable.

Hi,

I found your question online and I am looking for it as well. Did you find out where your can get the magnesium chloride powder?

Thank you

+2 for Mg

-2 for O
