We discussed several different reactions involving acids. for example, acids react easily with metals. when they do, what is one of the products that usually form?

a. water

b. salt

c. hydrogen gas

d. carbon dioxide

e. none of the above

When an acidic material reacts with a metal, they usually form hydrogen gas and a salt. For example, when hydrochloric acid (HCl) reacts with magnesium (Mg), it yields the products hydrogen (H) and magnesium chloride (MgCl). The reaction also leads to the release of heat since it is an exothermic reaction.
