Isooctane (C8H18; d = 0.692 g/mL) is used as the fuel during a test of a new automobile engine. How much energy (in kJ) is released by complete combustion of 10.6 gal of isooctane to gases (ΔH o rxn = −5.44 × 103 kJ/mol)? Enter your answer in scientific notation.

Attach the free body diagram and i will you answer the question.! : d

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.

Ruth ford over turned thomsons model in 1911 with his well known gold foil experiment in which he demonstrated that the atom has a tiny heavy nucleus rutherford designed an experiment to use the alpha particles emitted by a radio active element as probes to the unseen world of atomic structure. hey hope this
