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 ===================
How were the symbols magnesium and manganese formed?
Magnesium and manganese were formed through stellar nucleosynthesis, where nuclear fusion reactions inside stars convert lighter elements into heavier elements. Both magnesium and manganese were likely formed in supernova explosions, where the intense energy and pressure allowed for the synthesis of these elements.
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!
What is magnesium named after?
Magnesium is named after an ancient Greek city of Magnesia, near where it was first found.
Who found Magnesium?
Magnesium was first isolated by Sir Humphry Davy in 1808. He conducted an experiment using a mixture of magnesia (magnesium oxide) and mercuric oxide, and through electrolysis, he was able to isolate magnesium for the first time.

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.
How was magnesium discovered and by whom was it discovered?
Magnesium (Mg) was first obtained by English chemist Sir Humphry Davy in 1808. He produced it from the electrolysis of a mixture of magnesium oxide and mercuric oxide.

How do you calculate what mass of magnesium chloride is formed when 54.75g of HCl is reacted with sufficient magnesium?
By starting with a balanced equation. Mg + 2HCl -> MgCl2 + H2 when they say sufficient magnesium they imply that magnesium is in excess and HCl limits and drives the reaction, or that both are equal in molarity/mass 54.75 g HCl (1 mole HCl/36.458 g)(1 mole MgCl2/2 mole HCl)(95.21 g/1 mole MgCl2) = 71.49 grams magnesium chloride produced -----------------------------------------------------------
What is the first electron affinity of magnesium and is it exothermic or endothermic?
The first electron affinity of magnesium is exothermic. This means that energy is released when a neutral magnesium atom gains an electron to form a magnesium ion.
Is magnesium oxide a metal or non metal?
magnesium is neather a metal nor a non metal. instead it was discovered on the moon in 1899 on the first space walk. since then it has been used to build flame resistant bridges and the 2010 aero sun probe.

Why magnesium bicarbonate on heating does not give magnesiun carbonate?
Because the second (2) reaction is easier and quicker than the first (1) one will not find much MgCO3 in the reaction mixture, and further the escape of CO2 gas makes the last step irreversable.Mg(HCO3)2 --(1)-> 2MgCO3 + H2O --(2)-> 2MgO + CO2 + H2O(This is the same as saying magnesium carbonate is less stable than Mg-bicarbonate. At the higher temperature of Mg(HCO3)2 decomposition, MgCO3 is decomposed even faster)
