First, we assume that helium behaves as an ideal gas such that the ideal gas law is applicable.
PV = nRT
where P is pressure, V is volume, n is number of moles, R is universal gas constant, and T is temperature. From the equation, if n, R, and T are constant, there is an inverse relationship between P and V. From the given choices, the container with the greatest pressure would be the 50 mL.
We should apply Boyle's Law here given initial pressure, initial volume and final volume.
P1V1= P2V2
(6.5 atm) (13 L) = P2 (3.3 L)
Solve for P2 on your calculator and that should get you to the answer.
Particles in a liquid are more loosely packed there for they have more room to move and can flow around eachother . Hope this helps XD
I believe the answer is Na because it should be sodium which is Na.
The answer is electron.
The nucleus of a neutral potassium atom is "surrounded" by electron.
The neutral potassium atom contains equal number of protons and neutrons, and there are 19 electrons and 19 protons while 20 neutrons.
20 protons and 20 neutrons are there in the nucleus while 19 electrons surrounds the nucleus in different orbits .
