In a three-reaction system, the first two reactions are endothermic with AH values of AH1=101 kJ and AH2 = 358 kJ, respectively. If the final reaction is exothermic, what is the minimum value of AH3 that would make the overall reaction exothermic? Show your work and explain your reasoning very carefully.

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
