Which of the following is a statement of hess's law? if a reaction is carried out in a series of steps, the δh for the reaction will equal the sum of the enthalpy changes for the individual steps. the δh of a reaction depends on the physical states of the reactants and products. the δh for a process in the forward direction is equal in magnitude and opposite in sign to the δh for the process in the reverse direction. the δh for a process in the forward direction is equal to the δh for the process in the reverse direction. if a reaction is carried out in a series of steps, the δh for the reaction will equal the product of the enthalpy changes for the individual steps.

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.
