Climate change in Washington The main Global greenhouse Gas released in Washington include carbon dioxide (CO), methane (CH4), nitrous oxide (N2O), and other gases that contribute to global warming. The different emission types are placed into three categories: energy, industrial processes and agriculture. Different greenhouse gases range in their individual impact on global warming. For instance, one pound of nitrous oxide is 296 times more potent than a pound of carbon dioxide in contributing to global warming. This means even small quantities of gases emitted into the environment, like nitrous oxide, can have significant impacts on global warming. For Washington state in particular, energy
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.
