Consider the reaction 2H2(g) + O2(g) → 2H2O(g). The following bond energies have been determined experimentally: H-H 436 kJ/mol O=O 497 kJ/mol H-O 464 kJ/mol A. Suppose we start with 4 mol of hydrogen. How many moles of oxygen are needed to "use up" all of the hydrogen? How many moles of water molecules are produced? n of O2 = n of H2O = B. For the number of moles in part A, what is the difference in chemical energy between the reactants and the products for this reaction? (Give the absolute value only.) |ΔEchem| =
