Hydrogen gas (H2) is generated by the …

Hydrogen gas (H2) is generated by the following reaction. Ca(s) + 2 HCl(aq) → CaCl2(aq) + H2(g); ΔH = −542.7 kJ/mol When this reaction takes place in a cylinder (fitted with a piston) containing 1.000 mol Ca(s), 542.7 kJ heat is lost to the surroundings. Because a gas is generated, work is done by the system against a constant pressure of 1.140 atm. If the internal energy decreases by 545

Hydrogen gas is then fed into the retort; the retort is externally heated until the metal reaches its temperature of reaction; and the conversion of the metal to its hydride then begins. The exothermic heat resulting from the reaction tends promptly to elevate the temperature still further and the appliion of external heat to the retort is, therefore, discontinued.

Hydrogen sulfide - Wikipedia

Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms. H 2 S also occurs in volcanic gases, natural gas, and in some sources of well water. The human body produces small amounts of H

Depending on the metal alloy composition in lead-acid batteries, a battery being charged can generate two highly toxic by-products. One is arsine (arsenic hydride, AsH 3) and the other is stibine (antimony hydride, SbH 3).Generally, the air levels of these metal hydrides tend to remain well below the current occupational exposure limits during battery charging operations.
