Metals will release hydrogen gas when reacting with an acid (or in some cases, water). This is because acids contain hydrogen, and many metals are higher on the reactivity series than hydrogen, meaning they will replace it in a compound. For example, zinc reacts with hydrochloric acid
Zn + 2HCl --> ZnCl2 + H2
The zinc replaces hydrogen in the hydrochloric acid, forming zinc chloride and releasing elemental hydrogen in the process.

Do non metals liberate hydrogen gas from dilute. acids?
No. Metals liberate hydrogen gas from acids.

Hydrogen gas.
The gas evolved when metals react with dilute acids?
When dilute acids and metals are mixed you will get Hydrogen gas and salts
Do bases react with metals to produce hydrogen gas?
no.
What is the gas produced when metals react with acids?
Hydrogen
What type of gas is released in reaction between metals and acids?
hydrogen gas is liberated when an acid reacts with a metal.The equation is as follows acid + metal=salt + h2
What gas evolved when acids act on certain metals?
Hydrogen gas, H2
Who reacts with metal bases or acids?
Acids react with metals. Metals are themselves basic in nature. Metals displaces hydrogen from acids to liberate hydrogen gas.
