Nitric acid and Magnesium?
What type of gas is formed when a small piece of magnesium is added to 2cm of nitric acid in a test tube?

Mg + 2HNO3 --> Mg(NO3)2 + H2
Therefore, hydrogen gas... :)

It depends very much on the concentration of the acid.
Very dilute nitric(V) acid will form hydrogen, but as the concentration of the acid increases there will be increasing amounts of nitrogen oxides.
Test the gas given off with a lighted splint: does it pop? If so there is hydrogen present. Equally, if the gas evolved has a brown tinge then it contains some nitrogen dioxide.

As a basic greneral rule we say that. Metal + Acid -> Salt + Hydrogen Gas. So yes, its hydrogen gas.

It makes hydrogen gas.
