Evaluate-document based questionan explosion has just occurred and you and a group of your friends remember hearing oneof your classmates talking about how he has recently ordered a gilbert u-238 atomic energylab (1950-1951). in an effort the authorities you and your friends are trying to determinewhich unstable isotopes the kit contained. this information will the authorities learn howdeadly the explosion is for the surrounding people. 1. identify if the information below isscientifically in determining the identity of the element. 2. given the abundances andrelative masses, identify the unknown element and justify your answer by providinga claim, evidence, and reasoning.

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.
