What happens to the vapor pressure if we mix two volatile liquids (both have measurable vapor pressure)? PTotal = PA + PB = XA P°A + XB P°B

A.
Vapor pressure is smaller than vapor pressure of either pure liquid.
B.
Vapor pressure is larger than vapor pressure of either pure liquid.

C.
Vapor pressure is between vapor pressures of the pure liquids.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
