At room temperature its a solid white powder.
Metal.
When magnesium is heated, it undergoes a chemical reaction with oxygen in the air, resulting in the release of a gas called magnesium oxide (MgO).
The noble gas configuration of magnesium is [Ne]3s2.
I am assuming you are mixing Magnesium and Zinc metals with an acid which would produce Hydrogen gas.
The magnesium will react with the acid to produce hydrogen gas and a magnesium salt.
magnesium + dilute acid=magnesium dilute hydroxide and hydrogen
Magnesium nitride is formed when magnesium powder is burned in the presence of nitrogen gas.
Magnesium is a solid
The formula for magnesium and hydrogen gas is Mg and H2 respectfully.
When magnesium oxide is sufficiently heated, oxygen gas is evolved.
The chemical formula of magnesium chloride is MgCl2 and is not a gas. Magnesium chloride boil at 1 412 0C.
Magnesium element has no relation with noble gas. But Mg2+ ions and noble gas neon are isoelectronic.
when you mix sulphuric acid with magnesium you create a gas called hydrogen.
When magnesium is heated, it undergoes a chemical reaction with oxygen in the air, resulting in the release of a gas called magnesium oxide (MgO).
Magnesium Chloride and Hydrogen gas
Magnesium carbonate
Magnesium hydroxide and hydrogen gas
Its the same as normal Magnesium - Mg
