How were the symbols magnesium and manganese formed?
The chemical symbol of magnesium is Mg - the first and the third letter of magnesium. The chemical symbol of manganese is Mn - the first and the third letter of manganese.
How can you separate magnesium oxide into its elements?
Well, first you would heat magnesium in a crucible over a Bunsen burner, and this will cause the magnesium to react with both the oxygen and nitrogen in the air by the following equations: 2Mg(s) + O2(g) -> 2MgO(s) 3Mg(s) + O2(g) -> Mg3N2(s) Now you will want to purify the solution by getting rid of the MgN. To do that, you add water to the magnesium oxide and magnesium nitride and heat it, causing the water to react with the magnesium nitride by the following reaction: Mg3N2(s) + 6H2O(l) -> 2NH3(g) + 3Mg(OH)2(s) As you continue heating, the ammonia is driven off into the air, and the magnesium hydroxide decomposes by the following formula: Mg(OH)2(s) -> H2O(l) + MgO(s) Thus you are left with only MgO, because the during the heating the water is changed to gas and driven off as well. So all in all you added heat and water! Hope this helps!
How many grams of magnesium nitride can be made from 55.3 grams of magnesium if all the magnesium reacts only with nitrogen?
Balanced equation first. 3Mg + N2 -> Mg3N2 55.3 grams Mg (1 mole Mg/24.31 grams)(1 mole Mg3N2/3 mole Mg)(100.95 grams/1 mole Mg3N2) = 76.5 grams Mg3N2 made ===================
Why is magnesium called magnesium?
It is named for the ancient Greek city of Magnesia, where it was first discovered.
Is there calcium in cement?
Yes,Sorel in 1867 announced the discovery of an excellent cement formed from the combination of magnesium oxide and magnesium chloride solution. This cement type is known by many different names, such as Sorel, magnesite and magnesium oxychloride cement. This cement has many superior properties to Portland cement. However, there are two other known magnesia cements. The first is magnesium oxysulfate (MOS), which is the sulfate analogue of magnesium oxychloride and is formed by the combination of magnesium oxide and magnesium sulfate solution. The second is magnesium phosphate cement (MAP), formed by the reaction between magnesium oxide and a soluble phosphate, such as ammonium phosphate monobasic (NH4H2PO4)

What are compounds called?
I don't think there's an alternative name for them. An individual one is named by putting the metal first, then the non-metal with its ending changed to -ide. Examples: sodium and chlorine make sodium chloride. Magnesium and nitrogen make magnesium nitride.

What is magnesium ionization energy?
The first magnesium ionization energy is 737,7 kJ/mol.

Where magnesium is found?
Magnesium tarnishes slightly in air, and finely divided magnesium readily ignites upon heating in air and burns with a dazzling white flame. Normally magnesium is coated with a layer of oxide, MgO, that protects magnesium from air and water. magnesium is never found free in nature. Magnesium was first isolated by Sir Humphry Davy, an English chemist, through the electrolysis of a mixture of magnesium oxide (MgO) and mercuric oxide (HgO) in 1808. Today, magnesium can be extracted from the minerals dolomite (CaCO3·MgCO3) and carnallite (KCl·MgCl2·6H2O), but is most often obtained from seawater. Every cubic kilometer of seawater contains about 1.3 billion kilograms of magnesium (12 billion pounds per cubic mile).
When was magnesium first used?
Magnesium was mined in Greek times from the Magnesia region in Thessaly. Sir Humphry Davy isolated the metal in 1808 using electrolysis of a mixture of magnesia and mercury oxide. Dr. Antoine Bussy prepared it by heating a combination of magnesium chloride and potassium. Modern production is by electrolysis of brine containing its salts. In biology, plants use magnesium to produce chlorophyll, and human cells use it in the formation of DNA. It is poisonous in its pure form, and highly combustible.
When and how was Magnesium dicsovered?
Magnesium was discovered by Bussy in 1828AD. Magnesium was first isolated by Sir Humphery Davy in 1808AD as an impure metal.
