The temperature will increase the higher the mass of magnesium you add. It will increase the rate of the reaction.
The reaction is exothermic
magnesium + hydrochloric acid = magnesium chloride + water
Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)
Magnesium chloride plus hydrochloric acid is magnesium chloride and hydrogen gas.
Magnesium react easily with hydrochloric acid and magnesium chloride is obtained.
The reaction is exothermic
magnesium + hydrochloric acid = magnesium chloride + water
hydrochloric acid + magnesium => magnesium chloride + hydrogen 2HCl + Mg => MgCl2 + H2
Mg + 2HCl → MgCl2 + H2 magnesium+Hydrochloric acid→magnesium chloride+water (H2O)
Magnesium chloride plus hydrochloric acid is magnesium chloride and hydrogen gas.
Magnesium react easily with hydrochloric acid and magnesium chloride is obtained.
You can prepare hydrogen by adding magnesium to hydrochloric acid. hydrochloric acid + magnesium = magnesium chloride + hydrogen.
Magnesium hydroxide plus hydrochloric acid yields magnesium chloride plus water. Mg(OH)2 + 2HCl = MgCl2 + 2H2O
Magnesium
It could stop because there wasn't enough magnesium or hydrochloric acid for the reaction to go to completion.
Hydrochloric Acid
magnesium chloride + hydrogen
