One mole of an ideal gas at T1 = 300.0 K, p1 = 2.4618 atm, and V1 = 10.00 L is isother- mally expanded to V2 = 20.00 L against a constant external pressure of 1.2309 atm. Calculate ∆U, ∆H, q, w, and ∆S. Compare your results for ∆S and q/T and explain whether your results are consistent with the second law of Thermodynamics.

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
