Yes, best example, copper and hot concentrated sulphuric acid, that is a real nasty vigorous reaction! :D
When acids react with metals they can produce hydrogen.
Many acids will react with bases and, depending on the acid, some metals.
no all metals do not react with hydrochloric acids
For example uranium, mercury, vanadium don't react with water but can react with acids.
Hydrogen gas is produced when acids react with some metals. Protons are reduced as the metal is oxidized.
They do react vigorously.
Vigorously
No, Acids react with metals to form salts.
yes it true
All alkali metals and alkali earth metals below calcium react vigorously with acids.
False
