In the mid-1930s, Carus builds a new plant for the manufacture of two growing product lines, manganese sulfate and hydroquinone.
What was that chemical residue that a hand full of engineers claimed was found in the lower level of the twin towers?
Manganese(II) sulfate usually refers to the INORGANIC compound with the formula MnSO4·H2O.
Magnesium is also flammable, burning at a temperature of approximately 2500 K (2200 °C, 4000 °F).
Strange how a chemical plant that produces an inorganic substance that can melt steel to a liquid is over looked. Must be because the general public believes it's only used in crops otherwise with today's regulations those buildings would of had a fire suppression system.
Than you can go down a rabbit hole, periodic chart on hydroquinone and hydroxychloroquine.
