Emissions & Generation Resource Integrated Database mix, and heat input. eGRID data also include plant identification, location, and structural information. The emissions information in eGRID include carbon dioxide (CO), nitrogen oxides (NO), sulfur dioxide (SO), methane (CH), nitrous oxide (NO),and carbon dioxide equivalent (COe). CO, CH, and NO are greenhouse gases (GHG) that contribute to global warming or climate change. NO and SO contribute to unhealthy air quality and acid rain in many parts of the country. eGRID's resource mix information includes the following fossil fuel resources: coal, oil, gas, other fossil; nuclear resources; and the following renewable resources: hydroelectric (water), biomass (including biogas, landfill gas
Nitrous oxide careful heating of ammonium nitrate at about 250 C, which decomposes into nitrous oxide and water vapour. The addition of various phosphate salts favours formation of a purer gas at slightly lower temperatures. This reaction may be difficult to control, resulting in detonation. The decomposition of ammonium nitrate is also a common laboratory method for preparing the gas. Equivalently, it can be obtained by heating a mixture of sodium nitrate and ammonium sulfate: Another method involves the reaction of urea, nitric acid, and sulfuric acid: Direct oxidation of ammonia with a manganese dioxide-bismuth oxide catalyst has been reported: cf.
