A postulate is a statement recognized as a truth. The kinetic molecular theory has five postulates. Which of the following is NOT a postulate regarding the behavior of ideal gases in terms of kinetic molecular theory? Ideal gas particles are small compared to the space between them.

Particles must not be able to move in any fixed or open container.

Their collisions must be elastic and versatile.

There are no significant interactions among the particles of a gas.

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

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.
