Carbon dioxide in the atmosphere traps heat from the sun and makes life on Earth possible. Why then should we be concerned about adding carbon dioxide to the atmosphere if it is a natural occurrence and beneficial to life on Earth?

Why is it important to decrease the level of greenhouse gases in the Earth’s atmosphere?

Importance of carbon dioxide academically, personally, and to the society?

Why is carbon monoxide a dangerous air pollutant? How does it affect human health at low levels and at high levels?

While the majority component of air is nitrogen (N2), the gas is very unreactive because of its stability due to the triple bonds that hold the nitrogen atoms together.  Nitrogen gas is, therefore, relatively unavailable for chemical reactions.  One of the few ways to “fix” nitrogen, making a nitrogen compound from the elemental nitrogen in the atmosphere, is the Haber process (aka Haber-Bosch process).  In this reaction, nitrogen gas combines with hydrogen gas to yield ammonia.  The enthalpy (ΔH) of this reaction is 92.22 kJ.   This process was discovered by the German chemist Fritz Haber in the early twentieth century.  Through extensive experimentation, Haber found the conditions that would produce adequate yields (at a temperature of about 500 oC and a pressure of about 200 atm).  This process holds a significant importance today because of its application in the industrial production of ammonia-based fertilizer.  In 1918, Haber received the Nobel Prize in Chemistry for his work.…
