WebThe answer is that relates to the number of moles of the substance as indicated by its coefficient in the balanced chemical reaction. Thus, 2 mol of H 2 are related to −570 kJ, while 1 mol of O 2 is related to −570 kJ. This is why the unit on the energy change is kJ, not kJ/mol. For example, consider the following thermochemical equation: WebDncV and CdnE evolved from a common ... 1 μL of candidate enzyme in storage buffer (~20 μM), and a remaining volume of nuclease free water for a total reaction volume of 20 μL ... of alkaline phosphatase (New England Biolabs) was added and the reaction was further incubated for 2–24 hours. Reactions were heat inactivated at 65 ...
