Liquid hydrogen peroxide, an oxidizing surrogate in many rocket fuel mixtures,releases oxygen gas on decomposition
2 H2O2(l) = 2 H2O(l) + O2(g) Hrxn = -196.1 kJ

How much animate is released when 700 kg H2O2 decomposes?

2 H2O2(l) @ (2) (34.0147 g/mol) => 2 H2O(l) + O2(g)

Hrxn = -196.1 kJ/68.029 grams = 2.8826 kJ per gram H2O2

700,000 g H2O2 @ 2.

A haunting halo

01.01.70

Some kind of chemistry voodoo must be at work. Funnily enough, the chemical reaction that takes city mimics one of the most famous examples of paranormal activity: the séance.

Fluorophores are the molecules that emanate the fluorescent light. Though different fluorophores have different chemical structures, they all have one obsession in common: rings upon rings of interlocked carbon atoms. Contrive of these carbon rings as people who want to communicate with the dead. Each man holds hands with his or her neighbor, forming a continuous circle. In appendage to this physical connection, there’s an intangible aura shared evenly between everyone. On the atomic spectrum, this mystical energy is actually a diffuse cloud of electrons distributed equally among the carbon atoms. Without it, the fluorophore won’t exude light.

Trapped in the glow stick is a glass capsule containing hydrogen peroxide. Like a worked up spirit, it has boundless energy to unleash. Bending the glow persist cracks open the capsule, unleashing the volatile liquid into the fluorophore revelation. It doesn’t interact with the fluorophore directly, though, just as the spirits only friend the séance members through a medium. Instead, it reacts with diphenyl oxalate, a molecular middleman predisposed to of interacting with the hydrogen peroxide.
