Nineteenth-century electrolytic cell for producing oxyhydrogen. Oxyhydrogen is a mixture of hydrogen (H 2) and oxygen (O 2) gases.This gaseous mixture is used for torches to process refractory materials and was the first [1] gaseous mixture used for welding.
Nitrogen dioxide is a reddish-brown gas with a pungent, acrid odor above 21.2 °C (70.2 °F; 294.3 K) and becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K). It forms an equilibrium with its dimer, dinitrogen tetroxide (N 2 O 4), and converts almost entirely to N 2 O 4 below −11.2 °C (11.8 °F; 261.9 K). [6]
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
The mechanism of action was alleged to involve "Brown's gas", a mixture of oxyhydrogen with a ratio of 2:1, the same composition as liquid water; which would then be mixed with ambient air (nitrogen, oxygen, argon, etc). [4]

In all, the Congressional Research Service calculates the department manages more than 480 million acres of public lands, 700 million acres of subsurface minerals such as oil and gas, and 1.7 ...
Brown's Gas Vacuum Engine 1823. In patents dated 4 December 1823 and 22 April 1826, [4] Brown proposed to fill a closed chamber with a gas flame, and so expel the air; then he condensed the flame by injecting water, and operated an air engine by exhausting into the partial vacuum so obtained.
