Mandelic acid has a specific rotation of -158 degrees. What would be the specific rotation of a silution containing 40% (-) mandelic acid and 60% (+) mandelic acid?

the answer would be b i believe

it would be a gas formation

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.
