Elemental nitrogen is a colorless gas at room temperature. Under typical conditions, its density is 1.15g/L. Elemental oxygen is also a gas at room temperature. The density of oxygen gas is 1.31g/L. Under extreme
conditions, nitrogen can react with oxygen to produce brown nitrogen dioxide gas.
a. There is only one chemical property in the list above. State what it is. Explain.
b. None of the properties listed is an extensive property. Explain why not.
c. Calculate the volume of 2.50g of nitrogen and the volume of 2.50g oxygen using the densities give here.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
