Can oxygen exist as a liquid?
Yes, but under atmospheric pressure it must be cooled to 90 Kelvin, about -183 Celsius.
What proteins must always contain what elements?
These elememts are carbon, oxygen, hydrogen, phosphorus and nitrogen.
If the temperature remains constant800 mL of nitrogen at 2.0 ATM must be compressed to what pressure to reach 500 ml?
The pressure is 5,33 at.
What particle in a nitrogen atom must remain the same in order for it to stay a nitrogen atom?
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.
What elements are in magnesium nitride?
Nitride is an ion consisting of a single nitrogen atom with a 3- charge. This must be balanced by a positive ion, usually a metal ion. What metal it is can vary.
Why must nitrogen be used only with a regulator when it is charged into a system?
Nitrogen must also have its pressure regulated before it can be used. The pressure in the cylinder is too great to be connected to a system. If a person allowed nitrogen under cylinder pressure to enter a refrigeration system, the pressure could burst some weak point in the system.

Industrial deep-sea divers must breathe a mixture of helium and oxygen to prevent a disorienting condition known as nitrogen narcosis If a diver's tank is filled with a helium-oxygen mixture to a pre?
Industrial deep-sea divers must breathe a mixture of helium and oxygen to prevent a disorienting condition known as nitrogen narcosis. If a diver's tank is filled with a helium-oxygen mixture to a pressure of 170 atmospheres and the partial pressure of helium is 110 atmospheres, the partial pressure of the oxygen is ? - is the question The answer is 60. Total pressure minus the partial pressure= 170-110= 60.
Is nitrogen hazrdous?
If the air were pure nitrogen we would die. We must have oxygen, but the air is ~80% nitrogen and we don't die because it is not poisonous. For divers, there is a hazard from nitrogen dissolving in the blood at the higher pressures under water.
Can oxygen exist as a liquid?
Yes, but under atmospheric pressure it must be cooled to 90 Kelvin, about -183 Celsius.
The four most important elements that must be present in cell?
Carbon, Hydrogen, Oxygen and Nitrogen.
What proteins must always contain what elements?
These elememts are carbon, oxygen, hydrogen, phosphorus and nitrogen.
How does Oxygen Nitrogen and Xenon generate a compound O2N2Xe?
It should be ONXe but here it is O2N2Xe meaning there are 2 oxygen atoms, 2 nitrogen atoms and 1 Xenon atom. It must be a "special" compound

Which organic compound contains carbon hydrogen oxygen nitrogen and phosphorus?
which of these elements must be in organic compuonds oxygen hydrogen carbon helium or iron
Why must blood be under pressure?
because it can mate
