Conversion of molecules with C=C double bonds can be converted into molecules with a single C-C bond by addition of (reaction with) chlorine gas, Cl2(g). The balanced equation is shown below for reaction of ethylene with chlorine gas to make dichloroethane. Using the bond dissociation energy information provided in the equation, what is the enthalpy of this reaction as written, ΔHr, in kJ/mol?

Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim.An entomologist writes an article in a scientific journal which claims that fewer than 5 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Assuming that a hypothesis test to support this claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
