In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use 1/2mv ^2 for the solution but the answer I keep getting is nowhere near correct. Can someone help with this?
Explain the Nuclear Notation? Chemical reactions deal with the number of electrons exchanged or shared. Nuclear reactions, on the other hand, involve protons and neutrons and
