At 2:00 PM, a plant operator notices a drop in pressure in a pipeline transporting a volatile hydrocarbon. The pressure is immediately restored to 7 atmg. At 2:30 PM, a 1.2 inch diameter hole is found in the pipeline and immediately repaired. Provide a worst-case estimate for the total amount of hydrocarbon spilled in kilograms.

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.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
