Oxygen Gas Test |
You put hydrogen peroxide and mangese powder (catalyst), and the product of the two reactants make oxygen and water. Light a stick and the blow it out, and put into the test tube, and the stick will glow more, or completely relight. O2 relights a glowing stick makes test tube smoky manganese fizzes up |
