for a process, if the enthalpy change of a system is 1.25 ' 10^5 j and the entropy change is 300.0 j/ can someone me calculate the free energy change of the system at 290 k?

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?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples
