So i have been doing thsi question for about a week now and it's about liquid nitrogen. Here it is.
Liquid nitrogen is used in many low-temperature experiments. It is widely available, and cheaper than gasoline! How much heat must be removed from room temperature (20C) nitrogen gas to...
Hi. Can someone give me a hint to how to calculate total mass of nitrogen in the atmosphere. I've calculated the mass of all the atmosphere, I got the percent by volume of nitrogen to be 78.03 %. I converted the mass of the atmosphere to Liters. I got the volume of nitrogen to be 3.18e21 L and...
If one had no way of eating any protein, but could eat carbohydrates and something which had nitrogen that wasn't a protein, could their body assemble proteins to use, or does that mechanism not exist?
I was just reading something in my chem book about the nitrogen fixation process of bacteria. It said that trees need the bacteria to do this process. As a side thought, I think trees are mostly carbon, and a seed grows relatively fast. I was just wondering where does a seed get this large...
Problem 2. Liquid nitrogen, which has a boiling point of
77 K, is commonly used to cool substances to
low temperatures.
How much energy must be removed from
1.4 kg of gaseous nitrogen at 77 K for it to
completely liquefy? Assume the latent heat
of liquid nitrogen is 2.01 *10^5 J/kg Answer...
My friend and I have a lot of ideas for liquid nitrogen experiments (and we will be safe! :)), but we have no idea where to order it from. If from an online source, try to be specific. If in reality, try to give a little input on the process.
Thanks.
I cannot for the life of me solve this. Maybe one of you can help?
The solubility of N2 in blood at 37 degrees C and at a partial pressure of 0.8atm is 5.6 X 10-4mol/L. A deep-sea diver breathes compressed air with the partial pressure of nitrogen equal to 4.0atm. Assume the the total volume...
