solution: A sulfuric acid plant produces a considerable amount of heat. This heat is used to generate electricity, which helps reduce operating costs. The synthesis of H2SO4 consists of three main chemical processes: (a) oxidation of S to SO2, (b) oxidation of SO2 to SO3, (c) the dissolving of SO3 in H2SO4 and the subsequent reaction with water to form H2SO4. If the third process produces 130 kJ>mol, how much heat is produced in preparing a mole of H2SO4 from a mole of S

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
