How can you tell if a metal is reacting with an acid?
gas bubbles are produced

Describe how the reactivity of a metal affects its reaction with an acid.
very reactive metals such as potassium, sodium, and calcium react violently with acids, producing lots of gas bubbles, fire or even explosion.
What happens in a displacement reaction?
a more reactive element displaces a less reactive element from its compound
What is the reaction between an acid and an alkali called?
a neutralisation reaction
