Aim  to show that hydrogen gas is produced when a metal reacts with acid.
 Equipment A test tube, a boiling tube, Bunsen burner, wooden splint, a bottle of acid, a piece of metal, safety glasses
Method: 1) light your Bunsen burner
2) add your sample of metal to the test tube, Add 2 ml of acid
3) carefully invert the boiling tube above the test tube containing the metal and acid.
4) hold the test tubes together for a few minuets, allowing time for the inverted boiling tube to fill with gas
5) when you think the tube is full, you partner should light a wooden splint
6) carefully but quickly tip the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

Observation: We first put in the metal and acid the liquid got really hot in the test tube and  one well felt it was ready to have the splint put into it we lit it and put it in the test tube and it made a loud pop noise .

Outline how you could tell a chemical reaction was occurring in the test tube: when we out the splint in the test tube in made a loud pop noise.
