Mg(s) + 2HCl(aq.)----->MgCl2(aq.) + H2(g)
I am assuming you are mixing Magnesium and Zinc metals with an acid which would produce Hydrogen gas.
magnesium + dilute acid=magnesium dilute hydroxide and hydrogen
The reaction between hydrochloric acid (HCl) and magnesium (Mg) forms magnesium chloride (MgCl2) and hydrogen gas (H2), which is a chemical change. To reverse this reaction, you would need to separate the magnesium chloride back into its component elements and then convert the hydrogen gas back to magnesium and hydrochloric acid, which is not practical or feasible.
Magnesium chloride is formed in solution and hydrogen is released.
i am not sure but it seems that magnesium or mg + HCl = magnesium cloride MgCl. how would you account for the hydrogen ions? well you would have to balance the equation by 2Mg + 2HCl = 2MgCl + H2. so my answer would by hydocloric acid (HCl) No, that equation is WRONG! The correct equation is: Mg + 2HCl --> MgCl2 + H2. The H2 bubbles away as gas. The valency of Mg is 2+ and that of Cl is 1-.
The reverse reaction of hydrochloric acid and magnesium would be magnesium chloride and hydrogen gas. This can occur through the displacement reaction between the magnesium and hydrogen in the presence of an acidic solution like hydrochloric acid.
When sulfuric acid and magnesium metal are combined, a chemical reaction occurs where hydrogen gas is released. This reaction is exothermic, which means it releases heat. The magnesium metal dissolves in the sulfuric acid, forming magnesium sulfate and hydrogen gas.
hydrogen gas.. and it also produces a salt Mg(s) + H2SO4(aq) ¾ ¾ ® Mg2+(aq) + SO42-(aq) + H2(g)

When magnesium reacts with sulfuric acid, it produces magnesium sulfate, hydrogen gas, and heat. The reaction is exothermic and the hydrogen gas produced can be observed as bubbles. Additionally, magnesium sulfate is a white solid that can form as a precipitate in the solution.
Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)
When a piece of magnesium ribbon reacts with dilute hydrochloric acid, you would observe effervescence (bubbling) as hydrogen gas is released. The magnesium ribbon would dissolve in the acid, producing magnesium chloride solution. The solution may also become warm due to the exothermic nature of the reaction.
a magnesium salt of the acid, and hydrogen gas - water is already present.
Hydrochloric acid would react with the metal magnesium to produce magnesium chloride and hydrogen gas. This reaction involves the acid dissolving the metal to form a salt and releasing hydrogen gas as a byproduct.
Mg + H2SO4 --> MgSO4 + H2 It would appear that this bubbling is hydrogen gas rising to the surface of the solution.
Well, darling, when magnesium is added to a solution of sodium hydrogen sulfate, a chemical reaction occurs. The magnesium will kick sodium to the curb and form magnesium sulfate, while hydrogen gas gets released into the wild blue yonder. It's like a soap opera in a test tube, drama and chemistry all in one!
