2 confusing questions..someone please help! 1)Calculate the work (in kJ) done on the system when 2.20 moles of hydrogen gas are produced from the reaction of sodium in excess water at 298 K: 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g) 2)Calculate the change in entropy (in J/K) for the following reaction at 298 K: 2NO(g) +O2(g) → 2NO2(g) Use the data in Appendix II (Tro); Appendix 4 (Zumdahl) (When no amounts are given, it is for the reaction as written in moles. In this case 2 moles NO and 1 mole oxygen produce 2 moles NO2.)
