why doesn''t HNO3 liberate h2 gas when it reacts with …

because Nitric acid(HNO3) is a strong oxidising agent. The Hydrogen gas produced during its reaction with metal gets oxidised to H2O, hence no hydrogen gas is produced. Instead it evolves nitric oxides such as NO2,NO etc.

Review of the Coined Threats of Road Salts and Heavy …

Studies reporting heavy-metal concentrations in soils along roads suggest that heavy-metal contamination varies by country, depending on the nuer of vehicles using the road, the time since road construction, and the types of soil along the road (e.g20032009).

Phosphine and selected metal phosphides (EHC 73, 1988)

Phosphine is manufactured by the hydrolysis of metal phosphides, by the electrolysis of phosphorus in the presence of hydrogen, and by a phosphorus-steam reaction. It is produced incidentally by the hydrolysis of impurities in calcium carbide (in the production of ethyne (acetylene)), in ferrosilicon and spheroidal graphite iron, and in various metallurgical operations.
