Which two statements are true about energy transformations

In a given chemical reaction, the energy of the products is greater than the energy of the reactants. which statement is true for this reaction?

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
