Ara ello, realiza lo siguiente: 1. Describe con brevedad el ambiente físico y la escenografía. Esta será la descripción de escena que comúnmente aparece en las obras de teatro para ayudar a la compresión del lector.

the answer is

the dependant variable is spilled water

the independent is the heat

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.
