Electrons in metals are delocalized and in a free movement.
No. Metals liberate hydrogen gas from acids.
Acids can react with metals to produce hydrogen gas, not oxygen. When acids react with metals, they displace hydrogen gas from the acid.
When metals react with dilute acids, hydrogen gas is evolved. This is because metals displace hydrogen from the acid, resulting in the formation of metal salts and hydrogen gas as a byproduct. The reaction can be represented as metal + acid → metal salt + hydrogen gas.
neither. it is a noble gas
Metals react with acids to produce a salt and hydrogen gas.
Oxygen (O2) is the gas.
Several gasses can react with metals, but due to the fact that you are asking for a single gas, the most likely answer that you will be looking for is Oxygen. Oxygen reacts with many metals (and non-metals).
metals as in elements. or like zinc. or something. from my knowledge, magnets, other metals (sometimes), gas, && liquid.
When metals are put in hydrochloric acid, hydrogen gas is produced as the metal reacts with the acid to form metal chloride and hydrogen gas as a byproduct.
Its a gas
Yes.Yes.Yes.Yes.
Hydrogen gas, H2
