because some metals are less reactive than hydrogen.

YES METALS DISPLACES HYDROGEN FROM ACID FOR EX- Zn+H2SO4----->ZnSO4 + H2
acid +metal ->salt+ hydrogen eg sulphuric acid + magnesium -> magnesium sulphate+ hydrogen
hydrogen
salt and hydrogen :)

Nitric acid is an oxidizing agent
zinc magnesium aluminum iron nickel tin lead
Magnesium metal would displace hydrogen from Sulphuric acid and form Magnesium sulphate anh Hydrogen gas would be liberated.
Metal + Acid = Salt + Hydrogen Any metal that reacts with hydrochloric acid will form a metal chloride salt and hydrogen Sodium metal and hydrochloric acid

Metal+Acid=Salt+Hydrogen
Acid + Metal = Salt + Hydrogen
metal + acid -> salt + water metal + oxygen -> metal oxide metal oxide + acid -> salt + water metal + water -> metal hydroxide + hydrogen Metal + Steam -> Metal Oxide + Hydrogen Metal + Acid -> Metal salt + Hydrogen
The answer is during a metal reaction to acid, it makes salt and hydrogen. Another way is Acid + Metal > Metal Salt + Hydrogen
Acid will make a salt of that metal and free hydrogen, from the acid, if that metal is lower then hydrogen in the electro- motive series
acid +metal ->salt+ hydrogen eg sulphuric acid + magnesium -> magnesium sulphate+ hydrogen
