Why does liquid nitrogen exposed to air is a physical change?
Evaporation is a physical change; nitrogen remain nitrogen.
Is liquifying nitrogen a chemical change?
It is a chemical change because it can change back if you refreeze the nitrogen and it changed the chemical.
Is liquid nitrogen that boils AT - 196 degrees Celsius chemical or physical?
Physical change, as it goes from nitrogen liquid to nitrogen gas ... No chemical change takes place.
How many neutrons and protons are in an nitrogen atom?
There are 7 electrons in the stable variation of Nitrogen (the only time nitrogen isn't 7 electrons is when it is an ion, then it has 10 electrons). To find the amount of neutrons, you take the average atomic mass (14.007) and subtract the amount of protons (which is the same as the atomic number in an element, so 7) 14.007-7=7.007, 7.007 is the average amount of neutrons. There are different isotopes (atoms with different numbers of neutrons) however, the most common is 7 neutrons, but there is a Nitrogen atom with 8 neutrons, and there are more variations of isotopes that change the average amount of neutrons.
Why is it an advantage to transport nitrogen as a liquid rather than as a compressed gas?
The key to storing nitrogen as a liquid is that we need to compress and cool the nitrogen to cause it to change state from a gas to a liquid. By doing this, we can store a lot of nitrogen in a small volume compared to trying to store it as a gas.
What does respiration change?
Respiration (breathing) changes the amount of oxygen and carbon dioxide in the lungs
How does respiration change the amount of another gas in the atmosphere?
it doesnt
Which process explains the change in the positions of molecules after five hours?
respiration
What process in the cells of the maggots caused this colour change?
respiration
What danger we have to face if the proportion of oxygen and nitrogen in the air undergo a change?
Difficult respiration if the oxygen is under 20 % followed by death.
What is Certain bacteria change free nitrogen gas into a usable form in a process?
Nitrogen Cyclenitrogen fixationnitrogennitrogen fixationNitrogen-fixing bacteria
Why do the composition of air change when in the presence of a living organism?
Most likely because of biological respiration processes, when vertebrates and invertebrates take in oxygen (as well as air's main component: nitrogen) and expel carbon dioxide. For Plants, it is the reverse process, taking in carbon dioxide from animals and producing oxygen from the process.
Process where certain bacteria change nitrogen gas into nitrates in the soil?
denitrification
Why doesn't the total amount of nitrogen change?
Nitrogen makes up 78% of air, so we obviously breathe it in and because our body doesnt 'NEED' Nitrogen, so however much you inhale, you can exhale the same amount as none of the Nitrogen is used up. hope it helped ;p x
Is boiling nitrogen in a laboratory a physical or chemical change?
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..
Is respiration in animals a reversible change or irreversible change?
No, it isnt. There are chemical reactions while breathing.
Why does liquid nitrogen exposed to air is a physical change?
Evaporation is a physical change; nitrogen remain nitrogen.
