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

METHOD: 

 1 . light your bunsen burner 

2 . add your sample of metal to your test tube add 2 mL of acid 

3 . carefully invert the boiling tube above the test tube containing the metal and acid 

    (as shown in the diagram)   

4 . hold the test tube together  for a few minutes allowing time for the inverted boiling tube to fill with gas  

5 . when you think the tube is full your lab partner should light a wooden splint 

6 . carefully but quickly tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube 

hypothesis 

my hypothasis is when we put the metal in the acid it will bubble and pop



observation


when we put the acid in the tube with the metal it bubble and when we lit the splint and added it in the gas it pop the first time it didn't work but after awhile it did


conclusion  over all i like it because it was a fun and it was loud and it was a great experant
