Hi, we are looking for a list of moderate- highly endothermic equilibrium reactions which preferably only involve one particular state of all products and reactants involved. We have asked teachers and looked on the internet, but there is not much information. Due to this happening in a school, we also need the chemicals used to be suitable to use in a school lab. Any suggestions would be highly appreciated.

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.
