Please, please help... neutralization?
I am just really confused. I know that neutralization is a reaction in which an acid reacts with a base to form a salt and water. However, I am just wondering if the reaction between magnesium and hydrochloric acid would be a neutralization reaction because water is not formed. Thank you for answering if you do. :) x

In a neutralization reaction, you are correct, an acid combined with a base will produce a salt plus water. But if you combine magnesium with hydrochloric acid, what you have here is not a neutralization between an acid and a base, but rather what is called a "single-replacement reaction". Magnesium by itself is a simple element, not an acid or a base. Hydrochloric acid is a strong acid. The magnesium dsplaces the hydrogen, combines with the chlorine ion to make magnesium chloride, a salt, and liberates hydrogen gas. There are four types of basic reactions that would be helpful to remember. They are: 1) synthesis, which is this plus that will produce a new compound, 2) decomposition, the exact opposite of the synthesis, 3) the single-replacement, which is what you have here, and 4) the double replacement, where two compounds switch partners.
acid + base --> salt + water
BUT, magnaesium is neither a base nor an acid.
the reaction between magnesium and hydrochloric acid is as follows:
Mg + HCl --> MgCl2 + H2[gas]
