Full Answer

This chemical equation represents a reaction between the active metal magnesium and a strong acid. These types of reactions will always produce a salt and hydrogen gas. In this reaction, the salt is magnesium chloride.

Similarly, this is also a single replacement reaction in which the metal takes the place of another element in a compound. In this case, magnesium replaces the hydrogen in the acid, resulting in hydrogen gas being one of the products. The other product or magnesium chloride is a compound that has an atomic weight of 95.211 grams per mole.
