Answer:
When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide.
Metals react with water to form oxides or hydroxides and release Hydrogen gas.
An acid will react with a metal to form a salt and hydrogen gas. The general word equation for the reaction between an acid and a metal is as follows: acid + metal → salt + hydrogen.
