What is the absorption spectrum of NITROGEN DIOXIDE?
The absorption spectrum of nitrogen dioxide is in the ultraviolet region, with absorption peaks around 400-500 nm. These peaks correspond to transitions in the molecule that involve the excitation of electrons to higher energy levels. Nitrogen dioxide is a brownish gas due to its absorption properties in the visible range.
Like oxygen, we can also inhale nitrogen. Nitrogen is beneficial for health unless it's liquid nitrogen. Nitrogen helps us dissolve food waste to prevent deadly diseases from forming. The air we're breathing is mainly oxygen but sometimes we're inhaling nitrogen.
What is the importance of the nitrogen and carbon cycle to us?
The importance of the nitrogen and carbon cycle to us is critical to the survival of all living things on Earth. Nitrogen is absorbed by plants in the food creation process known as photosynthesis. The carbon cycle helps to reduce the amount of carbon in the atmosphere and return it to the soil to creat organic material.
How do plants get nitrogen compared to how animals get nitrogen?
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
Nitrogen and oxygen are individual elements with different properties.
Yes - but it usually takes high temperatures to get it to happen - like you get in internal combustion engines...
How many atoms are in 1.00 moles of nitrogen?
There are always the same number of MOLECULES in a mol.
That number is avogadro's number, "6.022×10^23". It's a huge number.
Now if instead of molecules we have single atoms, then you have 6.022×10^23 atoms in a mol. A mol is like saying "You have 6.022×10^23 parts of that." Regardless of what "that" is. I could have a mol of apples but it would be more apples than anyone has ever seen.
So the answer is 1 mol of Nitrogen is 6.022×10^23 atoms.
HOWEVER. Nitrogen as a species tends to be diatomic, so it's a little bit of a trick question. In most circumstances each molecule has 2 atoms (N2) so your answer is double. You have 6.022×10^23 molecules, but 12.044×10^23 atoms. Really the question isn't quite specific enough and you'll have to make a judgement on whether they mean elemental nitrogen or nitrogen as we commonly find it existing in nature.
How is notrogen fixation a necessary part of the nitrogen cycle?
Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that plants can use.
