At room temperature its a solid white powder.
... hydrogen gas. This is a displacement reaction in which magnesium displaces hydrogen in water to form magnesium oxide and hydrogen gas.
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).
2HCl + Mg ---------> MgCl2 + H2 Hydrogen chloride + Magnesium -------> Magnesium Chloride + Hydrogen gas
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.
The chemical formula of magnesium chloride is MgCl2 and is not a gas. Magnesium chloride boil at 1 412 0C.
HC2H3O2 is acetic acid. Magnesium will react with water or acids to produce hydrogen gas.
Magnesium is a solid
The word equation for the formation of magnesium oxide from magnesium metal and oxygen gas is: magnesium + oxygen → magnesium oxide.
Nitrogen gas does not react with magnesium under normal conditions. Magnesium is relatively unreactive with nitrogen at room temperature due to the strong triple bond in N2. Heating magnesium to high temperatures in the presence of nitrogen gas can form magnesium nitride (Mg3N2).
The formula for magnesium and hydrogen gas is Mg and H2 respectfully.
The Nobel gas abbreviation for magnesium is Ne.
Burning magnesium will go out in carbon dioxide gas.
Magnesium reacts with acid to produce magnesium ions and hydrogen gas. The magnesium metal dissolves in the acid while releasing hydrogen gas as a byproduct. This reaction is typically fast and exothermic.
... hydrogen gas. This is a displacement reaction in which magnesium displaces hydrogen in water to form magnesium oxide and hydrogen gas.
Magnesium element has no relation with noble gas. But Mg2+ ions and noble gas neon are isoelectronic.
When magnesium oxide is sufficiently heated, oxygen gas is evolved.
