All those metals which are present below Hydrogen in the reactivity series like Ag , Cu , Au , Pt ,etc.
Yes
Hydrogen. For example: Iron + water = rust + Hydrogen - Fe + (2)O2 = FeO2 + H2
when metal react with an acid it forms a salt and hydrogen gas
Hydrogen gas and metal cations
When a metal does react with water or hydrochloric acid , it drives hydrogen out and take its place
Acids.
Yes
Hydrogen gas is given off when metal reacts with acid. e.g. Zn + 2HCl ------> ZnCl2 + H2
Hydrogen is not a metal. It is a non-metal.
A metal more active than hydrogen in the electromotive series will react with an acid to form hydrogen gas.
Hydrogen. For example: Iron + water = rust + Hydrogen - Fe + (2)O2 = FeO2 + H2
when metal react with an acid it forms a salt and hydrogen gas
Hydrogen gas and metal cations

When carboxylic acid react with metal gives Salt and hydrogen
Hydrogen gas.
The acid may react which the metal to form a salt and release hydrogen gas.
