what is the word qusion formagneium+hydrochloric acid - magnesiumchloride+hydrogen
Magnesium hydrochloride
Is it a chemical change.
Magnesium nitrate (salt) and water are produced.
Magnesium oxide is a salt, but nitric acid isn't, and I don't believe that you would get a salt by mixing these two substances. Perhaps you meant to ask what salt is produced by mixing magnesium hydroxide and nitric acid; in that case you would produce the salt magnesium nitrate.
magnesium + hydrochloric acid = magnesium chloride + water
Magnesium hydrochloride
when you mix sulphuric acid with magnesium you create a gas called hydrogen.
Magnesium Oxide and Magnesium Carbonate are very different, Magnesium Oxide is Magnesium fused with Oxygen whereas Magnesium Carbonate is Magnesium fused with Carbon and Oxygen. The suffix "ate" means that an oxygen atom is involved. This added element (carbon) means that there will be a slight change in product. The chemical formula for Magnesium carbonate is MgCO3 whereas Magnesium oxide is MgO. See how there are two extra oxygens and one extra carbon? Add them together and you have CO2 and this is your difference. The difference in mixing magnesium oxide with sulfuric acid rather than mixing magnesium carbonate with sulfuric acid is that sulfuric acid and Magnesium carbonate create CO2 whereas Magnesium Oxide and sulfuric acid do not.

I am assuming you are mixing Magnesium and Zinc metals with an acid which would produce Hydrogen gas.
You can produce hydrogen gas by mixing sulfuric acid and magnesium to form hydrogen gas.
When mixing conc. sulfuric acid and water, add acid to water and not vice-versa as that releases lot of energy resulting in injuries.
The hydraulic acid doesn't exist; you think probable to a hydraulic fluid.
magnesium + hydrochloric acid = magnesium chloride + water
Hydrochloric Acid
