A scientist needs 80 mL of 3.6 M hydrochloric acid (HCl). She has a jug of 15.0 M HCl in the stock room. How much of the 15.0 M acid does she need to make her 3.6 M solution?

answer: a chemical reaction

explanation:

im not wrong

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.
