The "diameter" of an n2 molecule is roughly 360 pm. how far (in μm) does one molecule in a sample of pure n2 typically travel before colliding with another n2 molecule, if the gas is held at stp.

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

a is the answer to this question

explanation:

the answers would be

the first one and the second one
