science

aim: to show that hydrogen gas is produced when a metal reacts with acid.

equipment: a test tube,bunsen burner, wooden splint, a bottle, a piece of metal, safety, glasses, a boiling tube.

method: 1:light your bunsen burner.
2:add your sample of metal to your test tube.add 2ml of acid
3:carefully invert the boiling tube above the test tube containing the metal and acid {as shown in the diagram below}
4:hold the test to for a few minutes allowing time for the inverted boiling tube gas.
5:when you think the tube is full .your lab partner should light a wooden splint.
6:carefully but quickly till the boiling tube full of gas upwards and insert the burning splinter into the mouth of the test tube.

hypothesis:that when you put the metal in the acid it will start to pop.
my hypothesis was correct.

observation:  i also seen that when the put the magnesium in with the hci then lit a splint and put it in a tube it made a pop
