The main engines of the U. S space shuttle are powered by liquid hydrogen and liquid oxygen. If 1.02×10e5kg of liquid hydrogen is carried on a particular launch, what mass of liquid oxygen is necessary for all the hydrogen to burn. on a particular launch, what mass of liquid oxygen is necessary for all the hydrogen to burn.

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.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
