Calculate the enthalpy of the reaction: 2NO(g) + O2(g) --> 2NO2(g)?Calculate the enthalpy of the reaction: 2NO(g) + O2(g) --> 2NO2(g)given the following reactions and enthalpies of formation:1/2 N2(g) + O2(g) --> NO2(g), delta H *A = 33.2 kJ1/2 N2(g) + 1/2O2(g) --> NO(g), delta H *B= 90.2 kJCalculate the enthalpy of the reaction: 4B(s)+3O2(g) --> 2B2O3(s) given the following pertinent information:B2O3(s) + 3H2O(g) --> 3O2(g) + B2H6 (g) delta H *A = +2035 kJ2B(s) + 3H2(g) --> B2H6(g) delta H *B = +36 kJH2(g) + 1/2O2(g) --> H2O(l) delta H *C = -285 kJH2O(l) --> H2O(g) delta H *D = +44 kJCan someone show me step by step? I would be very grateful because I do not understand Hesss law very well.
