Describe how oxidation and reduction involve electrons change oxidation numbers and combine oxidation-reduction reactions

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.

How does the principle of electromagnetism explain the interaction between earth’s magnetic field and the solar wind?

About 3% of the water on earth is freshest. only about 40% of that freshwater is available for human use. why is so much freshwater unavailable for human use?
