A unrefined demo in chemistry courses involves adding a pint-sized speck of manganese(IV)oxide to a concentrated hydrogen peroxide solution. (H2O2) This produces oxygen gas and steam.

2H2O2 ---> 2H20 + O2
You can create the MnO2 over the arrow to show that it is a catalyst.

Having a rather down-to-three is trying tubes. In the tube at the first survey, was a restoration of zinc and about 1 / 2 mL of CuSO4 keys. Make a notation of observations. In the number two in the test tube add about 1 / 2 ml Ba (NO3) 2 elucidation of about 1 / 2 mL of CuSO4 resolution. Private comments. In the third party proves collecting tube of magnesium ribbon. Add about 1 / 2 mL of HCL decryption. Story comments. Taking account of a Bunsen burner (propane fire, C3H8). Achievements observations of the eruption. Touch the tube first review. Add about 2 mL H2O2 revelation.
