There are three bond pairs in NF3.The shape of NF3 is trigonal pyramidal.]]> 2020-11-16 04:53:54 UTC https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925762117 PHYSICAL PROPERTIES 2381961 https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925762359 Nitrogen trifluoride, NF3, is a colorless gas. It has a musty, pungent odor. It is slightly soluble in water. It is polar because the molecule forms a pyramidal shape. It melts at − 129 °C and boils at − 206 °C. It can be a potent oxidizer at an elevated temperature. Nitrogen trifluoride is an extremely strong greenhouse gas.]]> 2020-11-16 04:54:02 UTC https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925762359 CHEMICAL PROPERTIES 2381961 https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925762650 Nitrogen trifluoride is nonflammable and is a base. It is non-corrosive gas to steel, stainless steel and nickel. NF3  is a thermally-sensitive reactant, meaning that it will react with different compounds at different temperatures. It is toxic by inhalation and corrosive to tissue. ]]> 2020-11-16 04:54:12 UTC https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925762650 PRODUCERS 2381961 https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925763323 Use of NF3 began in the 1960s and 1970s in specialty applications. For example, it was used as a rocket fuel oxidizer and as a fluorine donor for chemical lasers. More recently, NF3 has grown rapidly in the manufacture of modern electronic devices. It has been used by in the semiconductor, computer chips, photovoltaic cell, and flat-panel display devices. It is also used in certain types of solar panels and chemical lasers. When nitrogen trifluoride is being used, some of it will always escape into the atmosphere. ]]> 2020-11-16 04:54:37 UTC https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925763323 HISTORICAL CHANGES 2381961 https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925763602 The amount of Nitrogen Trifluoride in the atmosphere has greatly increased overtime. In 1992, less than 100 tons were produced. The largest increase in the growth rate occurred between 2000 and 2006, when there was a significant relative rise in NF3 production and use. Now production has grown to an estimated 4,000 tons and is projected to increase significantly. Nitrogen trifluoride is now present in the atmosphere at four times the expected amount, and the atmospheric concentrations of NF3 are rising with a rate of increase of about 11% per year.

Once released into the atmosphere, this gas circulates from the surface to the stratosphere hundreds of times before it is destroyed by solar ultraviolet radiation.]]> 2020-11-16 04:55:05 UTC https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925764104 IMPORTANT CHEMICAL REACTIONS 2381961 https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925764398 Nitrogen trifluoride can react violently with hydrogen, ammonia, carbon monoxide, diborane, hydrogen sulfide, methane, tetrafluorohydrazine, and charcoal. It can have an explosive reaction with chlorine dioxide.

-It oxidizes hydrogen chloride to chlorine:
2 NF3 + 6 HCl → 6 HF + N2 + 3 Cl2
-It converts tetrafluorohydrazine upon contact with metals, but only at high temperatures:
2 NF3 + Cu → N2F4 + CuF2

It is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time (usually 100 years), relative to the emissions of 1 ton of carbon dioxide. Nitrogen trifluoride has a global warming potential of about 17,200. This means that it is 17,200 times more powerful than carbon dioxide in trapping atmospheric heat over a 100-year time span. This is much higher than most other greenhouse gases.]]> 2020-11-16 04:55:26 UTC https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925764702 WHY WE SHOULD CARE ABOUT IT 2381961 https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925764912 Nitrogen trifluoride is now present in the atmosphere at four times the expected level and this level is rapidly rising. This is a major problem for our atmosphere because NF3 is one of the most powerful greenhouse gases. It has a high global warming potential, and will trap heat in the atmosphere for 740 years! We need to draw more attention to this greenhouse gas because it is continuing to be produced at a very high rate due to the rapid growth of electronic devices. If this harmful gas continues to be emitted at this rate, it will greatly increase global warming, which will heat up the Earth's surface, warm our oceans, and have very negative effects on our environment.]]> 2020-11-16 04:55:34 UTC https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925764912 REFERENCE SOURCES FOR INFORMATION 2381961 https://padlet.com/2381961/xo5rexk9u9bwjfac/wish/925765153 https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2008GL035913
