Ammonia gas can be oxidized to nitrogen gas by silver oxide. At high enough concentrations, ammonia can be toxic to aquatic organisms. For example, increased ammonia concentrations may result in increased gill and organ damage, increased fin erosion, or increased mucous secretion in fish; possible changes in behavior include hyperexcitability, hyperventilation and convulsions. Consider the following unbalanced equation: Which of the following reaction mixtures would produce the greatest amount of product, assuming all went to completion? Example of a detailed conceptual diagram for ammonia.

With solid CuO and supply of heat, ammonia is oxidized to nitrogen gas and CuO is reduced to copper. Invertebrates, particularly arthropods, are generally less susceptible than fish. Give an example to support your case. [2][3] China produced 31.9% of the worldwide production, followed by Russia with 8.7%, India with 7.5%, and the United States with 7.1%. This is not meant to be a comprehensive bibliography of references dealing with ammonia, but rather is meant to highlight a few references that may be especially useful. . The NH 3 in the soil then reacts with water to form ammonium, NH 4 . Write a balanced chemical equation for this reation. This step is known as the ammonia synthesis loop (also referred to as the Haber-Bosch process): Due to the nature of the (typically multi-promoted magnetite) catalyst used in the ammonia synthesis reaction, only very low levels of oxygen-containing (especially CO, CO2 and H2O) compounds can be tolerated in the synthesis (hydrogen and nitrogen mixture) gas.
