Answer 1

Step-by-step explanation:

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.

The reaction of an acid with a metal:-

diatomic

density

characteristic

presence

chemist

pharmacist

Reaction of hydrogen and oxygen:-

The reaction between a tiny amount of hydrogen and oxygen in the air produces a characteristic 'pop' sound and this serves as test for the presence of hydrogen. You can watch the short video clip in the visit box in the margin to see this 'pop'.
