5. 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? a. It is much greater because real gas partides take up space.

b. It is much less because real gas particles are not moving.

c. It is much less because at high pressures the temperature drops.

d. There is no difference because the gas laws are always obeyed.

C. it is much less because at high pressure the temperature drops

let that person have a turn to speak : )

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
