That depends which acid and which metal. Most commonly, the gas produced is hydrogen (H2); however this only applies if the acid is a non-oxidising acid, such as hydochloric acid, sulphuric acid (dilute), acetic acid, hydrobromic acid etc. With nitric acid or chloric acid, both of these are strong oxidising agents and it is unlikely that any hydrogen will be produced (unless the acid is very, very dilute). For instance, with copper and concentrated nitric acid, the principal gaseous product will be nitrogen dioxide (NO2); with copper and dilute nitric acid, you'll get mainly nitric oxide (NO). With chloric acid and copper, the princpal gas given off will be chlorine dioxide (ClO2). Even sulphuric acid can act as an oxidising agent, if concentrated. So, copper and hot, concentrated sulphuric acid will give sulphur dioxide (SO2) as the principal gaseous product.

The hydrogen portion of the acid (usually an ionic compound) reacts with a basic portion on the metal. Water & a salt are often created during the reaction. Thus water vapor (steam) is produced as well as some escaping Hydrogen gas.

Hydrogen or water which depends on concentration of acid and metal involved in reaction

metal + acid = salt (metal salt) + H2 (hydrogen gas)

Hydrogen gas,or H2.
(For the previous posters,hydrogen is technically wrong. Hydrogen is the element H. Hydrogen gas,which is the gas in question, is H2.)
One example equation would be this. 2HCl + Fe = H2 + FeCl2
