Most nano·zymes react this compound with substrates like ABTS or TMB to trigger a color change. This compound is synthesized in a cycle that combines the elemental gases that reduce and oxidize a quinone (“quinn-own”). Luminol luminesces when it reacts (20[1])with (20[1])this compound. (20[1])This eco-friendly reagent kicks off classroom demos of chemical clock reactions when its reactive atoms are reduced from a minus-one to a (*) minus-two (0[1])oxidation state. Ethers are stored in amber bottles to stop (10[1])them from forming explosive derivatives of this compound. Dis·proportion·ating this compound produces oxygen and water, and breaking its weak single bond forms two hydroxyls. For 10 points, name this compound used in wastewater treatment and antiseptics, which has formula H2O2. ■END■ (10[1])
