Gaseous End Products

Gaseous forms of nitrogen include ammonia, nitrous oxide, and dinitrogen, which are readily lost to the atmosphere, and comprise approximately 1% of total nitrogen within a wetland. 

Nitrogen is exported from wetland systems via ammonia volatilization under alkaline conditions, where unionized ammonia in its gaseous form can be transported from soil and water column to the atmosphere. Another gaseous loss of nitrogen includes nitrous oxide and nitrogen produced during denitrification and emitted into the atmosphere. 

Other outputs include harvested plant biomass and detrital export (removing the nitrogen stored in the biomass, or simply wetland outflows where nutrients are exported in water and POM leaving wetlands such as in tidal marshes or riparian wetlands).

Explosive Substances vs Thermites. Accdg to Schimank et al, explosive substances are systems whioh are capable of exothermic chemical change, of a high reaction velocity, and which yield spontaneously gaseous end products wholly or in part... 

Thermites are systems capable of exothermic chemical reactions, of great (or relatively great) reaction velocity, but not yielding any gaseous end products. Examples of Thermites Al + Fe, Al + KC1C>3, etc Refs 1)H.Schimank, ZElektrochem 24, 213-14 (1919) 2)W.Bieger H.Schimank, Ibid,... 

Szymanski96 has investigated the effect of plasma formed in the presence of a ferroelectric sample (BaTiOj ceramic) on the decomposition of methane. Gaseous end products were similar to those obtained in other types of electrical discharges suggesting similar mechanisms. However, atomic spectra of Ba and Ti were observed indicating that the ferroelectric sample had been activated by the plasma.

Carbon dioxide and methane are two gaseous end products of decomposition of organic matter under anaerobic conditions, whereas only carbon dioxide is produced under aerobic conditions. Carbon dioxide readily dissolves in water and is partitioned into H2CO3, HCO , and CO as follows ... 

Gaseous end products (carbon dioxide and methane) produced during decomposition process are released into the atmosphere. 

Nitrite added to sterilized acid soils is rapidly converted to gaseous end products such as nitric oxide and nitrous oxide. 

Soil pH clearly influences the rate of denitrification as well as the distribution of gaseous end products. The optimal pH range for denitrification is at or near pH 7.0. The redox zone in wetland soils where nitrogen gas and nitrous oxide are formed is generally between -F150 and -1-250 mV (Figure 16.9).
