A scientist wants to perform a reaction in a vacuum chamber to control the experiment as much as possible and to prevent other
variables from impacting the reaction. The scientist is trying to determine if the reaction is endothermic or exothermic and
measure how much energy is absorbed or given off. Is this a sound approach? Why or why not? In three to five sentences,
explain your reasoning.

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.
