Has anyone done this experiment before? I need help with the final results. What would happen when I place 2 mL of hydrogen peroxide into 5 test tube, add manganese dioxide powder to the first one, then add sand to the second one, liver to the third one, and ground liver to the fourth one, and billed liver to the fifth one. On a scale of 0-10 how much bubbling occurs in each? What happens at each step? I can’t seem to get mine to work. I need results only. Thanks for any help!
