Explain how the Law of Conservation of Mass relates to stoichiometry.

19. at high pressures, how does the volume of a real gas compare with the volume of an ideal gas under the same conditions, and why? eman- it is much less because real gas partides are not moving. there is no difference because the gas laws are always obeyed. it is much less because at high pressures the temperature drops. it is much greater because real gas partides take up space.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

State one important difference between a physical change and a chemical change?
