Nitro compounds are explosive because although the diatomic form of nitrogen is very stable—that is, the triple bond that holds N 2 together is very strong, and therefore has a great deal of bond energy—the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and other atoms in nitro compounds are weak by comparison.
In fact, due to long-term impacts on food webs, Nr inputs are widely considered the most critical pollution problem in marine systems. [8] In both terrestrial and aquatic ecosystems, responses to N enrichment vary; however, a general re-occurring theme is the importance of thresholds (e.g., nitrogen saturation ) in system nutrient retention ...
The World Food Programme on Wednesday called the recent Afghanistan earthquakes a 'disaster on top of a disaster,' urging the international community to provide humanitarian aid to the war-torn ...
Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...
As the earthquake hit, the pair vowed to provide humanitarian aid to Turkey and Syria and have raised more than £11,000 on JustGiving to supply victims with blankets, food, baby clothes, heaters ...
Taiwan and its surrounding waters have registered about 2,000 earthquakes with a magnitude of 4.0 or greater since 1980, and more than 100 earthquakes with a magnitude above 5.5, according to the ...
However, the excessive or inefficient use of nitrogen fertilizers can lead to environmental problems such as nitrogen leaching, runoff, and emissions of nitrogen oxides (NOx). [4] Nitrogen leaching occurs when nitrogen compounds, primarily nitrates , move through the soil profile and enter groundwater, potentially contaminating drinking water ...
Flooding could impact food security for more than 5.6 million people across multiple African nations, a new study has found. While these impacts are usually negative, the researchers also ...
