This occurs because dissolved oxygen is consumed as bacteria and other microbes oxidize ammonia into nitrite and nitrate. Certain human activities and land uses can directly introduce ammonia into aquatic systems, and in many cases ammonia-related impairments are only seen when these direct discharges are present. So make two nitrogen atoms by adding two ammonia. This inhibition can result in increased ammonia accumulation in the aquatic environment, intensifying the level of toxicity to bacteria and aquatic animals (Carmargo and Alonso 2006). Almost every plant built between 1964 and 1992 had large single-train designs with synthesis gas manufacturing at 2535 bar and ammonia synthesis at 150200 bar. answer in g (6 marks QWC), Can someone solve this please? This reaction is a exothermic reaction and it emits -904 kJ mol-1. Many human activities and land uses also decrease riparian and watershed vegetation, which may decrease the amount of nitrogen taken up by terrestrial plants, and further reduce channel complexity due to reduced woody debris inputs.

In contrast, plant material is typically low in nitrogen, and associated decomposers may take up ammonia and reduce its aqueous concentration.
Chemistry of Oxygen (Z=8) - Chemistry LibreTexts For example, Na+ efflux rates are elevated in the presence of ammonia, and fish must increase Na+ influx to remain in Na+ balance. Temperature also affects the toxicity of ammonia to aquatic life. The Red River and Hamilton Harbor both have numerous municipal wastewater treatment plants discharging into them, and have shown high levels of ammonia in the past. Channel alteration and water withdrawals can reduce ammonia volatilization due to changes in water velocities and depths. Ammonia also exerts a biochemical oxygen demand on receiving waters (referred to as nitrogenous biological oxygen demand or NBOD). 0.25 mol SO3 Question: Ammonia gas reacts with oxygen gas, O2 (g), to produce nitrogen dioxide and water. Consider the equation: . I tried it and I got (C), but even my teacher says it's (B). [18] Most of their ammonia came from coal.
