Respuesta:
Mg2Ci + H2
Negative
Our numbers are small haha under each letter
The reaction of magnesium with hydrochloric acid produces as products a salt that is magnesium chloride plus hydrogen that is released. Therefore this proportion is false or incorrect.
The reaction of the element magnesium Mg with a strong acid such as HCl is a displacement reaction. A salt is formed which is magnesium chloride MgCl2 plus hydrogen gas that is evolved.
See the reaction
Mg + 2HCl ------- MgCl2 + H2
How it is observed magnesium dioxide MgO2 is not formed because it is not an oxidation reaction. Therefore the indicated proposition is incorrect or false.
