A). Object A, because the shorter the distance between objects result in a stronger gravitational force
The primary condition for a reaction to reach dynamic equilibrium is that "rate of forward reaction must be equal to the rate of reverse reaction." Furthermore, in a state of dynamic equilibrium, it has a unique synthesis wherein reactants are converted to products and vice versa.

Hello!
To know how many moles of iron can be recovered from 100 kg of Fe₃O₄ we'll need to use the
molar mass of Fe₃O₄ and apply the conversion factor to go from kg of Fe₃O₄ to moles of Fe in the following way:
So, theoretically, one could recover
1192,68 moles of Fe from 100 kg of Fe₃O₄
Have a nice day!
It would be S - 35 because people made the short form of each element to make it easier to understand and it is also used all around the world and 35 is the atomic number. Hope this helps ;)
