Hess's law states that "the heat released or absorbed in a chemical process is the same whether the process takes place in one or in several steps." It is important to recall the following rules: 1. When two reactions are added, their enthalpy values are added. 2. When a reaction is reversed, the sign of its enthalpy value changes. Part B 3. When the coefficients of a reaction are multiplied by a factor, the enthalpy value is multiplied by that same factor. Calculate the enthalpy of the reaction 4B(s) + 302 (9)→2B2O3(s) given the following pertinent information: A. B2O3(s) + 3H20(g)→302(g) +B2H6 (9), A;H = B. 2B(s) + 3H2 (g)→B2H6 (g), c. H2 (9) + 02(g)→H2O(1), +2035 kJ mol-1 A, H = +36 kJ mol-1 A,H = -285 kJ mol¬1 A, Hj = +44 kJ mol-1 D. H2 O(1)→H2O(g), Express your answer with the appropriate units. View Available Hint(s) HẢ ?
